A process for producing synthesis gas (syngas) comprising the endothermic reaction between CO 2 and H 2 S, wherein the energetic supply is provided by the exothermic oxidation of a small portion of H 2 S to SO 2 according to the following reaction scheme: R2: H 2 S + 1.5 O 2 → ...
This enables the production of hydrogen and solid carbon; the latter may potentially be used to replace hard coal in the coke and steel industries. In an additional innovative catalytic process step, carbon dioxide is combined with the hydrogen obtained from natural gas decomposition to produce syn...
Chemical looping reforming (CLR) of methane is a familiar process for the production syngas or hydrogen, which could be applied as one of the most important energy sources. In this process, reforming of methane takes place in the fuel reactor in contact with lattice oxygen of oxygen carriers ...
• Reversible process • Lower regeneration energy requirement (1.18 – 4 MJ kg CO2-1) • Low concentration of CO2 from flue gas (0.04 – 1.5 vol.%) • Poor selectivity – large pore size • Not suitable for separation at high temperature (> 800 °C) (Aaron and Tsouris, 2011...
Upon reaching a first target temperature, the process is then operated in a production mode to produce a second syngas with a higher CO/CO 2 molar ratio. Operation in a start-up mode until reaching a first target temperature, provides a process that is effective for reducing fouling in ...
(Supplementary Fig.21). The CO production rate drastically reduced after 6 h irradiation (Fig.4c). This may be because of the decomposition of photosensitizer under continuous visible-light irradiation49. Through the compositional engineering of the Co@Si SACs, we achieved an external quantum ...
Process Gas Analysis Fast and accurate measurement for various of gases in different industrial production processes is important. Cubic Instruments could offer syngas analyzers,biogas analyzers, natural gas analyzer and many other process gas analysis solution for optimized process control and quality assur...
sustainability analysis based on Aspen Plus simulator and Microsoft Excel is proposed.Three types of syngas production processes,including Kellogg natural gas steam conversion process,Shell pulverized coal gasification process,Shell residual oil gasification process,are presented to illustrate the proposed ...
2.The process of claim 1 wherein the fermentation zone produces a fermentation stream comprising an ethanol containing stream and the column overhead stream passes to a reaction zone for the production of ethylene. 3.The process of claim 2 wherein the fermentation zone converts syngas components...
An alternative syngas production process that has received extensive attention is the partial oxidation of methane to syngas. (2)CH4+1/2O2→2H2+CO,ΔHr=35.6kJ/mol High yields of syngas have been recorded for this process under various reactor configurations, contact times, and for various metal...
