Green coal, Quebec company poised to scale up biocoal technology
Near the St. Lawrence River, a stone’s throw away from the Gentilly nuclear power plant, the old LaPrade mill in Bécancour, Que., has come back to life. In one of the old concrete pools designed to produce heavy water, Airex Energy is testing its unique torrefaction process. Their goal: develop a large-scale biocoal technology made with forest biomass and agriculture waste. ...

Simultaneous removal of aqueous Zn2+, Cu2+, Cd2+, and Pb2+ by zeolites synthesized from low-calcium and high-calcium fly ash
In this study, zeolites were synthesized from low-calcium (LCZ) and high-calcium (HCZ) fly ash, respectively. Subsequently, the zeolites were tested for their removal effectiveness for four aqueous cations, namely, Zn2+, Cu2+, Cd2+, and Pb2+, as a function of contact time, pH value, adsorbent dosage, and initial concentration of heavy metals. Both zeolites were characterized by X-ray ...

Fly Ash & the Lightweight Aggregate Market
In 2015, the global fly ash market was estimated to be valued at 40 billion USD. A recent industry analysis by Research Nester anticipates the market will reach an estimated 70 billion USD by the end of 2023 – a 7.1% CAGR owing to increasing urbanization and a boost in construction projects. Along with bottom ash (BA) and flue gas desulfurization gypsum (FGD gypsum, or synthetic gypsum), ...

Continuous biosorption of nickel from aqueous solution using Chrysanthemum indicum derived biochar in a fixed-bed column
The biosorption capability of Chrysanthemum indicum to remove nickel ions from aqueous solution in a fixed-bed column was examined in this study. Native C. indicum flower waste was improved for its biosorptive potential by pyrolysis to obtain its biochar form and, thereby, both raw (CIF-R) and biochar (CIF-BC) forms of the flower were used for Ni(II) removal. Fixed bed column studies were ...

Offshore Wind Versus Solar in the Eastern US: An Unexpected Rivalry
Less than a decade ago, offshore wind energy and solar PV were similarly priced energy sources. Unsubsidized installed costs for both exceeded $5 per watt, or more than double that for land-based wind. Despite their cost, both technologies were seen as the best hopes for supplying urban centers with green power, especially in the BOSNYWASH (Boston-New York-Washington, DC) corridor of the eastern ...

Preparation of carbon-coated Fe3O4 porous particles and their adsorption properties of iron (III) ion
Carbon-coated Fe3O4 porous particles were synthesized with phenolic resin as a carbon source using impregnating pyrolysis. The magnetic property, phase structure, pore structure, and surface morphology of the pyrolysis products were characterized by vibrating specimen magnetometer, X-ray diffraction, Brunauer–Emmett–Teller (BET), and scanning electron microscopy, respectively. Also, the ...

As renewable electricity is added to the grid, are power markets misfiring?
When increasing megawatt-hours of variable solar and wind energy began coursing through the grid, the initial concern was an operational one—could grid reliability be maintained. But it turns out those megawatt-hours are creating market challenges, as well. What needs to be done to right the markets? Travis Kavulla, vice chairman of the Montana Public Service Commission, and Albert Cheung, ...

Best Biomass Carbonation Machine Currently Available
Whenever a chemical process called pyrolysis occurs, it can create a couple different products that are really profitable. Typically, plastic or rubber tires are utilized, but in addition there are ways to convert biomass to the same kind of products. There may be a whole lot biomass in the present day that may be produced through the process of harvesting lumber, all of which simply goes toward ...

Nuclear Waste Incineration (France) - Case Study
Nuclear waste incineration trials 1996 Glosfume successfully provided a pilot filter to carry out various trials on nuclear waste incineration. The filter was designed to operate under vacuum and passed all of the stringent requirements of French Nuclear Fuels. Similar filters have subsequently been used on several sites throughout France, contributing to reduced waste disposal costs and ...

Mobile Incinerators - Reaching the Places others Cannot
The new series of mobile incinerators from INCINER8 have widespread applications in waste management. These incinerators are used in farms, camps and shared facilities, and also help in controlling diseases in remote areas. The natural secondary burn characteristics of the primary chamber are considered to be one of the unique features of this range. This model is custom designed in a manner ...

Laboratory investigation of hydraulic characteristics of fly ash as a fill material from the aspects of pollutant transport
Depending on the usage of fly ash, it is necessary to determine its environmental parameters, such as the potential for pollutant transport/leaching after its built-in. This study presents a methodology for determination of transport parameters (filtration coefficient, effective porosity, longitudinal dispersivity, and the mean residence time) from experimental data collected from column ...

Why is Energy-from-Waste slow to catch on in the U.S.?
Nithin Coca reports in TriplePundit that Energy-from-Waste (EfW) is growing fast in Europe and parts of Asia. But it’s relatively stagnant here in the United States. In fact, the percentage of waste we burn for energy is actually slightly down in the past five years. What’s holding the U.S. back from this potentially sustainable solution? This stagnation is even more surprising when ...

Biomass and Integration in Future Energy Systems and the Bioeconomy
Biomass was the primary source of materials and energy until the industrial revolution set off a series of major changes around two hundred years ago. In the industrialized world fossil fuels became the primary source for energy in the forms of electricity and heat and provided almost all fuels for transport. However, biomass continued to maintain an important role in the economies in both ...

Cenospheres - Case Study
The problem: A cenosphere is a lightweight, inert, hollow sphere made largely of silica and alumina and filled with air or inert gas, typically produced as a byproduct of coal combustion at thermal power plants. On average 0.5% of the fly ash generated in a coal fired power station boiler are Cenospheres. When fly ash is wet discharged in to ash ponds/lagoons cenospheres float on the water ...

Rice Husk Charcoal Machinery That You Will Get At A Lower Price
Producing charcoal is actually a major industry. It really is easy to create charcoal utilizing a process called pyrolysis. Special machinery is produced that will be able to not just chip up all of the wood that will be process, yet it is then sent into a pyrolysis plant or machine which can help make the charcoal. This can be done for both a small and enormous-scale. There is always will be a ...

Why Are CHP Closing All Over The World?
Burning of coal nowadays has become a big problem. The main reason for this is a rapid increase of mankind. So, China burns half of coal in the world. Since 2000 the share of coal in world energy production has increased from 25 to 30%, and the Chinese economy is responsible for 82% of this growth. In Beijing, it is customary to use individual heat sources such as electric heaters and the like. ...
