Effects of Feed Composition and Feed Impurities in the Catalytic Conversion of Syngas to Higher Alcohols over Alkali-Promoted Cobalt–Molybdenum Sulfide [PDF]
Industrial & Engineering Chemistry Research, 2011 Alkali-promoted cobalt–molybdenum sulfide is a potential catalyst for the conversion of syngas into higher alcohols. This work is an investigation of how the feed composition influences the behavior of the sulfide catalyst. In a sulfur-free syngas the production of higher alcohols is observed to be optimal with an equimolar mixture of CO and H2 in the ...

Fuel, 2022 Catalytic reforming is a promising technology for the removal of tar from syngas. However, due to the presence of other impurities such as H2S, HCl, HBr, siloxanes, alkali metals, and NH3, the lifetime, activity, and stability of commonly used Ni-based catalysts is limited.

The effect of impurities on syngas combustion [PDF]
Combustion and Flame, 2015 Abstract The effects of chemical impurities on the combustion of syngas were investigated, focusing on CH 4 , a common component of syngas, and trimethylsilanol (TMS), an unstudied impurity related to those common to landfill-based syngas. Ignition properties were systematically investigated at high-pressure low-temperature conditions relevant to gas

A Systematic Review of Syngas Bioconversion to Value-Added Products from 2012 to 2022
Energies, 2023 Synthesis gas (syngas) fermentation is a biological carbon fixation process through which carboxydotrophic acetogenic bacteria convert CO, CO2, and H2 into platform chemicals.

Simultaneous removal of H2S and particulate matter by a multistage dual-flow sieve plate scrubber
Results in Engineering, 2023 In this work, an experimental study has been conducted in a newly designed and developed dual-flow scrubber with three sieve plates for simultaneous removal of hydrogen sulphide and particulate matter (fly-ash) from syngas produced in a gasifier as these

High-Temperature, Dry Scrubbing of Syngas with Use of Mineral Sorbents and Ceramic Rigid Filters
Energies, 2020 In this research, the idea of multicomponent, one-vessel cleaning of syngas through simultaneous dedusting and adsorption is described. Data presented were obtained with the use of a pilot-scale 60 kWth fixed-bed GazEla reactor, coupled with a dry gas ...

BioResources, 2014 Syngas from biomass gasifiers contains impurities such as tars and particulates, which can create difficulties for the downstream processes (e.g., internal combustion engines and the Fischer-Tropsch process).

Ignition delay time measurements behind reflected shock-waves for a representative coal-derived syngas with and without NH 3 and H 2 S impurities [PDF]
Proceedings of the Combustion Institute, 2015 Abstract The composition of a representative coal-derived syngas was determined by averaging 40 practical coal syngas compositions from the literature and corresponds to a departure from many recent studies which only focus on syngas blends containing just CO and H2.
