TL;DR: In this article, a new salt separator design for the supercritical water (or hydrothermal) gasification (SCWG or HTG) process was tested with two different setups using model solutions with water/2-propanol/Na2SO4/K 2SO4.
Abstract: The production of synthetic natural gas (SNG) via supercritical water (or hydrothermal) gasification (SCWG or HTG) offers the possibility to exploit the energetic content of biomass with a high water content. Separation and recovery of inorganic constituents present in the feed stream is crucial, as these constituents can lead to blocking of the plant, and to fouling and poisoning of the gasification catalyst. In addition, the recovery of salts offers the potential of producing a fertilizer as a valuable by-product. A new salt separator design for the SCWG process was tested with two different setups using model solutions with water/2-propanol/Na2SO4/K2SO4. The separation and recovery efficiency proved to be superior compared to the previously used salt separator. The sulfur recovery increased by a factor of 3.5–7 and the sulfur accumulation decreased by a factor of 2–10 using the novel design.

TL;DR: In this article, the technical feasibility and optimal reactor combination for a simple two-stage methanation process producing substitute natural gas (SNG) was identified for an isothermal fluidized bed at 723-823 K combining a tail end fixed bed.

TL;DR: The road transport sector today is almost exclusively dependent on fossil fuels as mentioned in this paper and it will need to face a radical change if it aims to switch from a fossil-based system to a renewable-b...

TL;DR: In this article, a novel system concept is presented for the thermochemical conversion of very wet biomasses such as sewage sludge and manure, which integrates steam drying, solid oxide electrolysis cells and gasification for the production of synthetic natural gas (SNG).

TL;DR: In this article, a carbonaceous material gasification zone, in series with a (water gas) shift conversion zone, a sulfur compound and carbon dioxide removal zone, and a methanol synthesis zone, was discussed.
Abstract: OF THE DISCLOSURE Methanol and synthetic natural gas are concurrently produced by operating sequentially a carbonaceous material gasification zone, in series with a (water gas) shift conversion zone, in series with a sulfur compound and carbon dioxide removal zone, in series with a methanol synthesis zone and in series with a methanation zone.
