TL;DR: In this article, a process for producing a substitute natural gas, the process comprising the steps of: (1) providing a synthesis gas comprising hydrogen and carbon monoxide; (2) forming a hydrogen-enriched synthesis gas; (3) subjecting the hydrogen-enhanced synthesis gas to a methanation reaction to convert at least a portion of the gas into methane; and (4) recovering from the methane-enhaged gas a methane-containing gas, wherein step(2) comprises providing a hydrogen gas and combining the hydrogen gas with the synthesis gas.

TL;DR: In this article, the authors described a synthesized composite catalyst for methanation, a method for manufacturing the same and a method of use thereof, which consisted of a carrier; and nickel and iron carried in the carrier.
Abstract: The present invention relates to a synthesized composite catalyst for methanation, a method for manufacturing the same and a method of use thereof. According to an embodiment of the present invention, the synthesized composite catalyst for methanation comprises: a carrier; and nickel (Ni) and iron (Fe) carried in the carrier. The synthesized composite catalyst for methanation comprises, with respect to 100 wt% of the catalyst, 35 wt% or more and 45 wt% or less of Ni, 3 to 5 wt% of Fe and the residual carrier.

TL;DR: A hydrogen/oxygen gas blended substitute fuel is provided to save energy and prevent global warming phenomenon by reducing harmful air pollutants such as NOx, soot and smoke, CO, HC etc. and increasing the content of oxygen contained in a combustion fuel at the same time.
Abstract: A hydrogen/oxygen gas blended substitute fuel is provided to save energy and prevent global warming phenomenon by reducing harmful air pollutants such as NOx, soot and smoke, CO, HC, etc. and increasing the content of oxygen contained in a combustion fuel at the same time. A hydrogen/oxygen gas blended substitute fuel comprises 10 to 95% by volume of LNG(Liquefied Natural Gas), LPG(Liquefied Petroleum Gas), SNG(Substitute Natural Gas), coalified gas, or fossil fuel, and 5 to 90% by volume of a hydrogen/oxygen gas mixture in which hydrogen gas and oxygen gas generated by electrolyzing water are mixed at a ratio of 2:1. The substitute fuel is used in city gas, industrial gas, and engines.
