  • Process for the Separation of Gas Products from Waste Tire Pyrolysis

    In recent years, pyrolysis has proven to be an effective thermochemical process for the recycling of waste tires. After pyrolysis, three fractions are obtained:  carbonaceous solids, liquid hydrocarbons, and the so-called noncondensable gases. In this paper, the starting point is the pyrolysis reactor outlet that provides a gas stream with a temperature of 600 ...


  • Advanced Application of Product Gases of Thermal Conversion of Biomass and Waste; Integration With the Fischer-Tropsch Synthesis

    The Netherlands Energy Research Foundation (ECN) is studying the advanced application of product gases from the thermal conversion of biomass and waste (B&W). The Fischer-Tropsch (FT) synthesis is the most promising as it affords diesel-like fuels of high quality and free from sulfur and aromatics. A slurry bubble FT reactor with an iron catalyst is the most suitable for B&W syngases. To optimize ...

  • New methods of hydrogen production are being deployed which are helping increase the efficiency of biomass facilities, creating high value clean energy from sources of waste

    Biomass can easily be converted to hydrogen using decade’s matured, highly reliable technology that is simply applied in non-standard ways. In large scale anaerobic digesters and other biogas projects (including landfill gas) you can maximize the utility of the natural gas product by converting it to high purity hydrogen fuel. In modern gasification plants, operators will effectively be ...

  • Biolimp siloxa for plant for biogas cleaning

    The biogas produced in a digester, landfill or waste water plant is normally treated in order to remove water, H2S, dust and/or CO2. The choice of the cleaning method employed and the compound to be removed depends on the type of end use of the gas. This paper focuses on desing, star up and operation of biogas cleaning plant for removal dangerous component (water, H2S, NH3, siloxane and ...

  • Effects of a zeolite SCR system on comprehensive emissions from a heavy-duty diesel engine

    The effects of a zeolite urea-selective catalytic reduction (SCR) aftertreatment system on a comprehensive spectrum of chemical species from diesel engine emissions were investigated in this study. Representative samples were collected with a newly developed source dilution sampling system after an aging process designed to simulate atmospheric dilution and cooling conditions. Samples were ...

  • Nuclear power: ecologically sustainable or energy hot potato? A case study

    We are facing the prospect of fossil fuels running out. The magnitude of the hydrocarbon resource gap and lack of alternative energy sources leaves us with few choices. The gap between supply and demand must be met through either increased efficiency or increased nuclear/renewable energy production. With the proposed development of ten nuclear power stations, government appears committed to using ...

  • High density polyethylene (HDPE) pyrolysis plant

    Thermal degradation of plastic polymers is becoming an increasingly important method for the conversion of plastic materials into valuable chemicals and oil products. In this work, virgin high-density polyethylene (HDPE) was chosen as a material for pyrolysis. A simple pyrolysis reactor system has been used to pyrolyse virgin HDPE with an objective to optimize the liquid product yield at a ...

  • Fugitive Gas Emissions In The Petroleum & Natural Gas Industry

    Challenge: Fugitive emissions in the petroleum and natural gas industry can come from a variety of sources and are classified as intentional (venting from tanks, compressor vents and stacks) or unintentional (equipment wear and tear, improper assembly, damage or manufacturing defects).  Most of these fugitive gas leaks are considered insignificant or  too small to ...
