Liebgott, H

A process is described for producing high-methane gas. It comprises: catalytically cracking liquid hydrocarbons with water vapor at elevated temperatures and pressures to produce a rich gas containing less than 15 percent hydrogen by volume; cooling the rich gas below its dew point to a temperature below 150/sup 0/C thereby reducing the water vapor content thereof by condensation; separating condensed water from the rich gas; thereafter dividing the rich gas into two streams and feeding same to a hydrogenation zone containing two catalyst layers, and scrubbing the product gas leaving the hydrogenation zone to remove carbon dioxide.
