TL;DR: In this article, future demand for non-fossil produced hydrogen and its potential are oriented toward two, to some extent competing goals: on one hand, its direct utilization as a gaseous or liquid energy carrier and, on the other, its use in the manufacture of synthetic natural gas and synthetic liquid energy carriers from coal, tar sands and oil shale.
Abstract: Estimates of future demand for non-fossil produced hydrogen and of its potential are oriented toward two, to some extent competing goals: on one hand, its direct utilization as a gaseous or liquid energy carrier and, on the other, its use in the manufacture of synthetic natural gas and synthetic liquid energy carriers from coal, tar sands and oil shale. At present the second thrust is meeting with more interest because it is viewed as economically feasible at an earlier date, requiring changes in conversion techniques but not changes in usage [10.1–10.3]. However, it is as damaging to the environment as the present fossil energy economy [10.4, 10.9].

TL;DR: For refining pyrolysis products into marketable products such as synthetic natural gas, gasoline, diesel and raw materials for the chemical industry, this paper coupled with the catalytic reforming of the pyrolysate in one process step.
Abstract: For refining pyrolysis products into marketable products such as synthetic natural gas, gasoline, diesel and raw materials for the chemical industry, the pyrolysis of solid fuels and organic wastes is coupled with the catalytic reforming of the pyrolysate in one process step. Acidic mineral catalysts (for example aluminosilicates) are either directly mixed with the fuel or arranged spatially separately in the reaction space. Depending on the composition of the starting products and the desired end products, extraneous steam is fed for reforming.

TL;DR: In this paper, an air preheat burner consisting of a heat absorption pot and a burning cavity formed in the heat absorption Pot is described. And the burning cavity is further provided with an ignition device and a plurality of air nozzles, and an air guide body is arranged above the air inlet and used for guiding air to flow to the inner wall of the heating cavity from the air-inlet.
Abstract: The utility model discloses an air preheat burner installed rapidly. The air preheat burner comprises a heat absorption pot and a burning cavity formed in the heat absorption pot. An air inlet is formed in the bottom of the heat absorption pot, the bottom of the burning cavity is connected with a fuel gas input pipe, the burning cavity is further provided with an ignition device and a plurality of air nozzles, and an air guide body is arranged above the air inlet and used for guiding air to flow to the inner wall of the heat absorption pot from the air inlet. The air preheat burner installed rapidly is suitable for different environments, stable in burning, convenient to install, easy to maintain and suitable for natural gas, substitute natural gas, LPG and mixed gas sources.

TL;DR: In this article, the authors present a process for hydromethanating a carbonaceous feedstock to a methane-enriched raw product stream, and more specifically to processing of solid char byproduct removed from the hydromithanation reactor to improve the carbon utilization and thermal efficiency and economics of the overall process.
Abstract: The present invention relates generally to processes for hydromethanating a carbonaceous feedstock in a hydromethanation reactor to a methane-enriched raw product stream, and more specifically to processing of solid char by-product removed from the hydromethanation reactor to improve the carbon utilization and thermal efficiency and economics of the overall process by co-producing electric power and steam from the by-product char in addition to the end-product pipeline quality substitute natural gas.
