CATALYTIC REDUCTION OF CARBON DIOXIDE TO METHANE AND WATER
Abstract
A literature search was conducted to determine suitable candidate catalysts for the Sabatier reaction. The test system for evaluating the candidate catalysts material included a reactor sized to handle 2.5 lbs of CO2 per day, equivalent to one-man output. The optimum catalyst was determined to be Ru metal powder, having a bulk density of 85 lb/cu ft, and an average particle diameter of .002-.003 inches. The minimum temperature required with this catalyst to provide over 99% conversion of CO2 was 357 F., at one atmosphere, a H2:CO2 ratio of 4.4 and a space velocity of 310/hr. During a thirty-day duration test with ruthenium metal powder CO2 conversion remained essentially at 99%, and the catalyst remained unchanged. The theoretical equilibrium reaction limitations are discussed in the report.
