Metals resulting from plasma pyrolysis can be recovered from the slag and eventually sold as a commodity. Inert slag produced from some processes is granulated and can be used in construction. A portion of the syngas produced feeds on-site turbines, which power the plasma torches and thus support the feed system. [8]
Syngas, or synthesis gas, is a mixture of hydrogen and carbon monoxide, [1] in various ratios. The gas often contains some carbon dioxide and methane . It is principally used for producing ammonia or methanol .
] Pyrolysis gas has a high percentage of heavy tar fractions, which condense at relatively high temperatures, preventing its direct use in gas burners and internal combustion engines, unlike syngas. The process is used heavily in the chemical industry , for example, to produce ethylene , many forms of carbon , and other chemicals from petroleum ...
The resulting syngas can be combusted. Alternatively, if the syngas is clean enough, it may be used for power production in gas engines, gas turbines or even fuel cells, or converted efficiently to dimethyl ether (DME) by methanol dehydration, methane via the Sabatier reaction, or diesel-like synthetic fuel via the Fischer–Tropsch process. In ...
The syngas is an important intermediate for generation of such diverse products as electricity, chemicals, hydrogen, and liquid fuels. The motivation for developing the CLR and CLG processes lies in their advantages of being able to avoid the use of pure oxygen in the reaction, thereby circumventing the energy intensive air separation ...
The process consists of gasification, plasma gas treatment, syngas polishing and gas engine power generation. It will be designed to produce gas for powering vehicles, power, heat and aggregate glass from processing 7500 tonnes of refuse-derived fuel annually. Construction is expected to start during 2016 [12]. [13]
Oil shale gas is produced by retorting (pyrolysis) of oil shale. In the pyrolysis process, oil shale is heated until its kerogen decomposes into vapors of a petroleum-like condensable shale oil, non-condensable combustible oil shale gas, and spent shale—a solid residue. [2]
Initially biomass undergoes pyrolysis process to produce pyrolysis gases and biochar.The volatile organic compounds in pyrolysis gases further undergo gasification process to produce syngas rich in hydrogen and carbon monoxide gases which is further converted in to methanol (CH 3 OH). [3]
