    • High-methane gas which can be used in place of natural gas is made byA. catalytically cracking liquid hydrocarbons with water vapor at elevated temperatures and pressures to produce a rich gas containing less than 15% hydrogen by volume;B. cooling the rich gas to a temperature below 150.degree. C thereby reducing the water vapor content thereof by condensation;C. separating condensed water from the rich gas;D. thereafter hydrogenating the carbon oxides in the gas by dividing same into two streams, one of the streams being preheated to a temperature of at least 250.degree. C and then being introduced into the first catalyst layer of a hydrogenation zone containing two catalyst layers, the other of the streams being fed at the temperatures produced in cooling step (b) between the catalyst layers of the hydrogenation zone; andE. scrubbing the product gas leaving the hydrogenation zone to remove carbon dioxide.Preferably, the ratio of the two streams is adjusted such that the temperature rise in the second catalyst layer of the hydrogenation zone is less than 50.degree. C and the product gas leaving the hydrogenation zone contains less than 1% hydrogen by volume.
    • 可用于代替天然气的高甲烷气体由A.通过水蒸汽在高温下以液体的形式催化裂化液体碳氢化合物产生含有低于15%氢气的大量气体的压力; B.将大量气体冷却至低于150℃的温度,从而通过冷凝降低其水蒸汽含量; 从丰富的气体分离浓缩水; D.将气体中的碳氧化物加氢分解成两个流,其中一个流经至少250℃的温度,然后被引入含有两个催化剂层的氢化区的第一催化剂层中, 在冷却步骤(b)中在氢化区的催化剂层之间产生的温度下进料另一个; 和E.将产品气体放出加氢区以移除二氧化碳。
