The amorphous alloy catalytic converter for methanation reaction of carbon monoxide which is included in the hydrocarbon reformed gas which features that the amorphous alloy catalytic converter for methanation reaction of carbon monoxide being included in hydrocarbon reformed gas
PROBLEM TO BE SOLVED: To convert CO, CO2 and H2 in reformed gas of hydrocarbons into methane by their reaction using a catalyst obtd. by subjecting an amorphous alloy consisting of Zr and at least one of Co and Ni as a precursor to oxidation- reduction treatment. ;SOLUTION: An amorphous allay consisting of 20-80 at.% Zr and the balance essentially at least one of Co and Ni is used as a precursor and subjected to oxidation-reduction treatment to obtain the objective amorphous alloy catalyst 1. Reformed gas 6 of hydrocarbons enters a 1st reaction tube 2 from the top and CO, CO2 and H2 in the gas 6 cause exothermic methanation reaction producing methane and water in the presence of the catalyst 1. The gas 6 is then cooled to the original temp. fit for methanation reaction with a cooler 5 in a passage 3 and produced water 7 is separated. The remaining gas enters the upper part of a 2nd reaction tube 2, methanation reaction is caused again in the presence of the catalyst 1 and the gas leaves the tube 2 from the bottom.;COPYRIGHT: (C)1998,JPO
