Catalytic coal gasification is being developed as a more efficient and less costly approach to producing methane from coal. With a potassium catalyst all the reactions can take place at one temperature, so that endothermic and exothermic reactions can be integrated in a single reactor. A key aspect of the concept involves continuous recycling of product carbon monoxide and hydrogen to the gasifier following separation of methane. Development of the process has advanced steadily since the basic concept was proposed in 1971. A 23-day demonstration run was recently completed in a process development unit with a coal feed rate of 1 ton per day. The next major step in the program will be to design and construct a large pilot plant to bring the technology to commercial readiness in the late 1980's.
催化煤气化正在被开发为一种更有效率、成本更低的从煤中生产甲烷的方法。使用钾催化剂，所有的反应都可以在一个温度下进行，这样吸热和放热反应就可以在一个单一的反应器中集成。该概念的一个关键方面涉及到在甲烷分离后将产品一氧化碳和氢气连续循环回气化炉。自 1971 年提出基本概念以来，该工艺一直在稳步发展。最近，在一个每天进料 1 吨的工艺开发装置中完成了一次为期 23 天的示范运行。该计划的下一个主要步骤是设计和建造一个大型中试厂，以使该技术在 80 年代末达到商业准备状态。
