TL;DR: In this article, the Chalmers gasifier provides unique possibilities to investigate the important parameters for this optimization by in-situ measurements in an industrial sized installation, and demonstrates an innovative possibility to retrofit existing heat or heat and power plants for gas production.
Abstract: A cost-effective production of second generation biofuels require highly efficient gasification processes. For Substitute Natural Gas (SNG) to compete with natural gas, a cold gas efficiency of over 80 % related to the biomass dedicated for the gas production is required. Furthermore, as much “instant” methane as possible should be produced already during gasification. To optimize the gasification process towards a distinct product is a challenging task. The Chalmers gasifier provides unique possibilities to investigate the important parameters for this optimization by in-situ measurements in an industrial sized installation. It also demonstrates an innovative possibility to retrofit existing heat or heat and power plants for gas production. The gasifier is designated to research and, therefore, equipped with a multitude of sampling ports spread out over the front of the reactor. By means of different probes, sampling of gas and bed material is possible to acquire information of the progress of the fuel-conversion. A first set of measurement data from sampling of gas and bed material was successfully achieved during the firing season 08/09 and results from these measurements are presented in this paper.

TL;DR: In this article, a process for the production of a pipeline gas of high BTU content from crude oil by hydrogasification of the crude oil is described, which is first vaporized in the presence of hydrogen and then gasified to form an effluent gas containing essentially methane, ethane, aromatic hydrocarbons, hyrogen and hydrogen sulfide.
Abstract: A process for the production of a pipeline gas of high BTU content from crude oil by hydrogasification of the crude oil. The crude oil is first vaporized in the presence of hydrogen and then gasified to form an effluent gas containing essentially methane, ethane, aromatic hydrocarbons, hyrogen and hydrogen sulfide. After separation of the aromatics and hydrogen sulfide from the effluent, the effluent is subjected to cryogenic separation of the hydrogen and a final catalytic conversion of the ethane to methane.

TL;DR: In this article, the characteristics, applications and potential of different processes and reactor types are discussed, and new processes which require minimum feedstock preparation and preferentially producing medium calorific value gas without the use of oxygen, should be developed.

TL;DR: In this article, the CO2 methanation process, which yields synthetic natural gas (SNG) via the synthesis of CO2 and H2 through proton exchange membrane (PEM) water electrolysis using surplus electricity generated from renewable energy, was evaluated and optimized based on techno-economic analyses.
