CONVERSION OF METHANE AND LIGHT HYDROCARBONSINTO HYDROGEN CONTAINING GAS ON MEMBRANECATALYTIC SYSTEMSFedotov A., Tsodikov M., Moiseev I.PP-18A.V. Topchiev Institute of Petrochemical Synthesis, Russian Academy of Sciences,Leninsky pr., 29, Moscow, 119991, Moscow, Russia, alexey.fedotov@ips.ac.ruThis work is devoted to study of original membrane catalytic systems (MCS) [1],high active in dry and steam reforming of methane and light hydrocarbons intohydrogen containing gas that can be used in petrochemichal industry or in compactelectric generators.MSC represent porous ceramic membranes prepared by self-propagating hightemperaturesynthesis from high dispersive Ni-Al powder and modified by nano sizemetal oxide La-Ce, Pd-Mn, Pd, Mn [2] and Au-Ni containing precursors using sol-gelmethod. Experiment conditions: T = 350 – 800°C; P = 1.5 – 30 atm; W feed = up to25000 h –1 ; C 1 -C 5 /CO 2 /H 2 O in various proportions.By using MCS in dry methane reforming (DMR) process we have achieved thefollowing syngas productivities: 10500 for La-Ce and 7500 l/h·dm 3 membr. for Pd-Mncontaining MCS; syngas composition (H 2 /СО) was 0,63 and 1,25, respectively;conversion of initial gas mix (CH 4 /СО 2 =1) was ∼ 50% in both cases. We have foundthat on MCS, dry methane reforming is in one order more intensive at moderatetemperatures (350 – 650°C) than in a traditional reactor with a fixed bed layer of thesame catalyst [3]. We have proposed an energy production method using MCS as asyngas generator in a compact integrated scheme based on solid-oxide fuel cells inwhich methane and light hydrocarbons (C 2 -C 4 ), contained in gases of incompletecombustion of hydrocarbon fuels, convert into syngas at high feed rate (∼ 25000 h –1 )by dry-steam reforming process.References:[1].
