Fuel processor comprises fuel reformer, water gasshift reactors (HTS and LTS WGSR) and reactor of fine CO removal. The purpose of ourstudy was to increase the efficiency of the last two steps. We suggest to apply a reactor withoptimal temperature profile in the catalyst’s bed for one stage WGSR and prefferential COmethanation process for fine cleaning up of fuel gas from CO. The obstacle of preferential COhydrogenation consists in the presence of about 20 vol. % of CO 2 along with 1 vol. % of CO.Highly effective (active and stable in a wide temperature range, 380-210 o C) Cu- containigcatalyst for WGSR has been developed. With the aim to provide the temperature control in thecatalyst’s layer the thermal conductive catalyst plates (TCP) based on the developed catalyst forcompact WGSR reactors have been prepared and studied. High thermal conductivity of2.5–5 W . (m K) -1 can be achieved, while the effective catalytic activity of TCP is even higherthan that of the commercial size catalyst grains. In the TCP reactor WGSR the fuel gascontaining 12 % of CO can be processed in one stage at GSHV of above 6000 h -1 down to 1 %of residual CO. The TCP shape and the way of arrangement have been optimized.Highly active and selective in kinetic field nickel-containing catalyst NM-1 wasdeveloped for CO prefferential methanation. Special form - permeable composite material(PCM) - has been prepared on the base of NM-1 catalyst (PCM-NM-1), providing the finefuel gas purification to CO concentration 10-20 ppm in the wide range of GHSV from 6000 to17000 h -1 with the selectivity of above 0.5.Acknowledgements.
