ge ch4 process

The process is, typically, much faster than steam reforming and requires a smaller reactor vessel. As can be seen in chemical reactions of partial oxidation, this process initially produces less hydrogen per unit of the input fuel than is obtained by steam reforming of the same fuel. Partial oxidation of methane reaction CH 4 + ½O 2 → CO ...

  • Wafer-scale fabrication of single-crystal graphene on Ge(1

    Nov 01, 2020By directly monitoring the growth process of graphene via atomic force microscopy, it is found that under high CH 4 /H 2 ratio condition new graphene domains ceaselessly nucleate and enlarge during the whole growth process, while under low CH 4 /H 2 ratio condition, the density of graphene domains is saturated at early stage, which causes the formation of single-crystal graphene.Author: Tianbo Wang, Panlin Li, Xudong Hu, Min Gao, Zengfeng Di, Zhongying Xue, Miao Zhang

  • One‐Step Reforming of CO2 and CH4 into High‐Value Liquid

    Aug 25, 2017Recently, Ge and co‐workers investigated the direct C−C coupling of CO 2 and CH 4 to form acetic acid on a Zn‐doped ceria catalyst by density functional theory (DFT) modeling; 1 this is an attractive route as the direct conversion of CO 2 and CH 4 into acetic acid is a reaction with 100 % atom economy [Equation 1].

  • Anaerobic Digestion of Wastewater Sludge

    Overall, the process converts about 40% to 60% of the organic solids to methane (CH4) and carbon dioxide (CO2). The chemical composition of the gas is 60-65% methane, 30-35% carbon dioxide, plus small quantities of H 2, N2, H2S and H2O. Of these, methane is the most valuable because it is a hydrocarbon fuel (giving 36.5 MJ/m3 in combustion).
