用于生产富甲烷产品气流的改进方法,包括以下步骤:使用2.2至2.9的H2O/燃料重量比和0.80至0.84的基本上纯的氧中的氧与燃料中的碳的原子比部分氧化烃燃料进料以产生主要包含H2的工艺气流,CO和CH 4,其中H2/CO摩尔比为1至2.5,CH 4摩尔%为15或更大,并且颗粒碳为13重量冷却工艺气流并分离H2O、CO2、碳和气态杂质;使所述工艺气流中的H2和CO在催化甲烷化区中一起反应以产生主要包含CH 4并含有选自H2、CO、H2O、CO2及其混合物的气体成分的富甲烷气流;和除去所述H2O和CO2以产生包含约93摩尔%的CH 4的富甲烷产物气流。通过本发明,可生产出每SCF约960 BTU或更高的高热值清洁燃料气或替代天然气。
Improved process for the production of a methane-rich product gas stream comprising the following steps: partial oxidation of a hydrocarbonaceous fuel feed employing a H2O/fuel weight ratio of 2.2 to 2.9 and an atomic ratio of oxygen in the substantially pure oxygen to carbon in the fuel of 0.80 to 0.84 to produce a process gas stream comprising principally H2, CO and CH4 in which the mole ratio H2/CO is 1 to 2.5, the mole % CH4 is 15 or more, and the particulate carbon is 13 weight % (basis carbon in the fuel) or less; cooling the process gas stream and separating H2O, CO2, carbon, and gaseous impurities; reacting together the H2 and CO in said process gas stream in a catalytic methanation zone to produce a methane-rich gas stream principally comprising CH4 and containing gaseous members selected from the group consisting of H2, CO, H2O, CO2, and mixtures thereof; and removing said H2O and CO2 to produce a methane-rich product gas stream comprising about 93 mole percent of CH 4. By means of the subject invention there is produced a high heating value clean fuel gas or a substitute natural gas of about 960 BTU per SCF or more.
