大规模生产氢气和合成气的工艺基本相同。合成气中氢和一氧化碳的比例可能从1到2不等。一个每天生产2.5万桶初级液体燃料的工厂每天需要7亿到8亿立方英尺的合成气。低成本的合成气需要使用价格较低的发电机燃料，这些燃料最好在连续的内部加热过程中使用氧气进行气化。制氧所需的能量的一部分，如果不是全部，可以从合成反应器中放出的热量中获得。主要工艺包括：Winkler，在固定床气化煤粉；Koppers，悬浮气化煤粉；鲁奇，在固定床上加压气化煤粉；Thyssen-Galocsy和Leuna，气化块燃料，并将灰烬作为熔渣处理。关于前述内容，简要讨论了其他方法。得出的结论是，使用悬浮粉状燃料的气化工艺最能满足美国的要求。这将允许使用等级较高的粘结煤或非粘结煤，以及等级较低的亚烟煤或褐煤。
Processes for the large-scale production of hydrogen and synthesis gas are basically identical. The ratio of hydrogen to carbon monoxide in the synthesis gas may vary from 1 to 2. A plant producing 25,000 barrels of primary liquid fuel per day requires from 700,000,000 to 800,000,000 cubic feet of synthesis gas per day. Low-cost synthesis gas requires the use of lower priced generator fuels, which can best be gasified in continuous internally heated processes using oxygen. Part, if not all, of the energy requirements for oxygen production may be obtained from the heat evolved in the synthesis reactors. The principal processes include: Winkler, gasifying fines in a fixed fluidized bed; Koppers, gasifying pulverized coal in suspension; Lurgi, gasifying fines in a fixed bed under pressure; Thyssen-Galocsy and Leuna, gasifying lump fuel and disposing of the ash as a molten slag. Other processes are briefly discussed in relation to the foregoing. It is concluded that American requirements may best be satisfied by gasification processes using pulverized fuel in suspension. These will permit the use of higher rank caking or noncaking coals, as well as the lower rank subbituminous coals or lignite.
