Taylor - Biomass Gasification Process Technology
As the first step in the Taylor Biomass Gasification Process, The Taylor Sorting and Separating Process receives the waste streams, removes and recycles appropriate material, where commodity markets exist and prepares the biomass fraction of the waste stream for gasification. In municipal waste streams, biomass includes paper, fiber, food residuals, leather, some textiles and wood products. In its advanced separating process,
Taylor removes painted and pressure treated woods ...
Taylor removes painted and pressure treated woods due to potential environmental concerns during gasification. These two materials will continue to go to Alternative Daily Cover (ADC) markets until new markets are identified for these two wood products. Small quantities of plastics present in the waste stream are acceptable feed materials for the Taylor gasification process. PVC is removed from the fuel stream using advanced infra-red technology. Developed through years of expertise and regarded as a trade secret, this highly-effective process minimizes or eliminates potential environmental issues by removing (for recycling or disposal), in-organics and household hazardous waste, painted or treated wood, brick, gypsum, dirt and fines, electronics, and other materials that are not appropriate biomass. The Taylor Sorting and Separating Process succeeds in producing a cost-effective and stable supply of biomass feedstock, overcoming one of the major market obstacles to successful commercialization of promising gasification technologies. Most existing facilities are built to use only one type of biomass. TBE’s innovative solution utilizes the entire spectrum of biomass.
Part B: The Taylor Gasification Process
As the second step in the Taylor Energy Solution, the patent-pending Taylor Gasification Technology uses indirect heat and the biomass feedstock prepared by Part A to efficiently produce a Medium heating value gas. Unlike the low heating value gas produced in air-blown gasifiers, the gas produced through the Taylor Gasification Process can serve as a direct substitute for natural gas, or can be used as a fuel for engines, gas turbines, or as a synthesis gas (syngas) for the production of chemicals or hydrogen. The Taylor Gasification Process has significant and important impact for the future of electric power, transportation fuel, and alternative treatment for mixed solid waste (MSW) and construction and demolition debris (C&D). TBE’s solution makes significant improvements over other more conventionalgasification technologies and radically improves the characteristics of the valuable synthesis gas.
Part C: Diversity of Product Slate
Historically, biomass has merely been used for heating. Today's developing energy technologies are broadening the uses of biomass well beyond simple combustion for heating. The flexibility of biomass as an input to conversion processes provides the ability to generate a wide range of energy products. If a medium calorific value gas, such as that produced in the Taylor gasification process, is generated from the biomass as the primary step in the conversion process, the potential product slate is virtually limitless. Potential end uses of this medium gas can include such diverse products as gaseous products that can substitute directly for natural gas, liquid fuel products such as ethanol, Fischer Tropsh liquids or direct gasoline substitutes, chemical intermediates such as acetic acid or methanol, fertilizers, polymeric materials, gasoline additives such as DME, and other products currently produced from petroleum sources. In addition other products ranging from fuel gas to steam, electric power, or hydrogen can readily and economically be produced from gasification-generated synthesis gas.
The Taylor Energy Solution as a unique integration of three separate components (Part A, Part B and Part C), designed as one integrated system.None of the generic component technologies in the three separate processes systems are new. The unique Taylor approach, however provides significant enhancements and innovation to each segment of the overall integrated process system and effectively the A, B & C components to solve the future challenges of waste disposal and alternative energy generation.
The Taylor Biomass Gasification Process What is it, how does it work, what are its advantages?What is it?
- An environmentally clean method to separate biomass and recyclables from waste such as Construction and Demolition (C&D) debris and Municipal Solid Waste (MSW) and efficiently produce renewable, sustainable, alternative electricity from biomass
- An indirectly heated biomass gasification process
- No air or oxygen in the gasification reactor – removes almost all toxic residue
- Uses compact circulating fluidized bed reactors
- Includes in-situ (within the main process) residual tar conversion into additional useful syngas
- Simplified and more effective gas cleanup
- Improved heat recovery
- Organics reduced in waste water (and waste water recycled for process use)
- High energy syngas composition eliminating the need for further scrubbing
- Provides high hydrogen concentrations without additional downstream processes
- Potential for hydrogen recovery in the future
- Gas suitable for synthesis applications (production of transportation jet fuels or chemicals)
How does it work?
- In the process, a circulating, catalytically active, heat carrying material (sand) is used to rapidly heat the incoming biomass, convert it to syngas, and convey unconverted biomass (char) from the gasification reactor into an associated combustor.
- In the gasification reactor, biomass from the sorting and separating system is surrounded by sand and steam. No air or oxygen is added so there are no combustion reactions taking place, providing minimal emissions and environmental impact. The biomass is rapidly converted into medium calorific value synthesis gas at a temperature of approximately 1500F.
- Unconverted biomass (char), and the cooled sand, pass through the gasification reactor and then are separated from the synthesis gas.
- The synthesis gas continues on to the gas conditioning reactor, while the sand is conveyed into the associated combustion reactor.
- In the gas conditioning reactor, steam in the product gas reacts with condensable materials in the gas (tars) to produce carbon monoxide, hydrogen, and low molecular weight hydrocarbons such as methane and benzene, all used for power generation or the production of chemical products. In addition, some carbon monoxide is converted into hydrogen by reaction with steam.
- In the combustion reactor, hot air is introduced which consumes the char and, in the process, reheats the sand to approximately 1800F. In the combustion reactor all remaining carbon is consumed, resulting in a carbon-free ash (about 10% of biomass processed in gasifier).
- The reheated sand is separated from the flue gas (exhaust) and returned to the gasifier.
- Ash is removed from the exhaust, resulting in a high temperature (1800F) clean flue gas stream, available for heat recovery.
- The process operates at essentially atmospheric pressure, simplifying the feeding and handling of the incoming biomass.

- The proposed 300 dry tons per day Taylor Biomass Energy (TBE) gasification project in Montgomery will reduce our fossil fuel dependency by approximately 240,000 barrels or 10,000,000 gallons of oil per year, producing 24MW gross renewable, alternative energy.
- The current Taylor-Montgomery plant is union affiliated with The International Laborers Union. The project currently employees 35 employees. The biomass gasification expansion will add approximately 70 new union jobs.
- The expanded Montgomery project will require the payment of approximately $1.8 i n new taxes to the local town, school and fire district according to the Town Assessor’s office.
- The Montgomery project proposes to take the MSW from Orange County municipalities, and County Waste Co., which will deliver the waste to the Montgomery project, reducing long haul trucking. There it will be sorted, separated, recycled as feasible, and prepared as organic biomass for silo storage before the biomass gasification process.
- This will produce renewable, alternative energy, generated locally and distributed into a nearby electric power substation eliminating the need for new electric transmission power lines and corridors through the area.
- The Montgomery project has township building and zoning permits; New York State DEC environmental permits; and a 20-year contract to sell all electric power produced to the New York State Power Authority.
- The project will utilize a project union labor agreement for construction by its engineer, procure, construct (EPC) contractor.
- The TBE process stops wasting our waste which is a valuable resource; and it stops creating permanent large mountains of waste and overflowing landfills.
- The TBE process is a more environmentally friendly method of processing our waste, with clean, green sustainability.
- We are one of the first counties in the world to have a private company take in the municipal waste stream plus construction and demolition debris within its normal service area (30-mile radius), and to recycle 97% of it into remanufactured products (including electricity).
