**The specified amount of coal-to-natural gas is not less than 2 billion cubic meters. Most of the planning is 4 billion cubic meters. It seems that the maximum value currently in use is around 1.33 billion.
One can take a look at the several coal-to-natural gas projects that have recently passed environmental impact assessments, as well as those that are already in operation; it’s not difficult to find them
Coal-to-gas production facilities come in various scales; the largest ones in China have a capacity of 1 billion cubic meters per year. This process features a simple flowchart, with the preceding stages such as air separation, gasification, and purification being technologies that are already well-established. As for methane synthesis, the David process is currently the preferred method on a large scale. This company has already applied its second-generation technology in China, with the key improvements lying in the design of the main reactor and the use of second-generation catalysts on an industrial scale.
The total capacity is regulated; it seems that there are documents stating it should be no less than 2 billion cubic meters per year. In China, the typical capacity is 4 billion cubic meters per year, with 4 production lines – though some designs include 3 production lines, in which case the capacity per line would be 1.33 billion cubic meters per year
