| description | The invention relates to a method for producing tar and hydrocarbon fuel products with coal. The method comprises the steps such as pyrolysis, coarse gas purification and desulfuration, methanation reaction, gasification reaction, transformation reaction, purification treatment, sulfur recovery procedure, fine desulfurization treatment and synthesis procedure. According to the method provided by the invention, raw coal is subjected to low-temperature pyrolysis and then subjected to gasification transformation, which not only increases the number of categories of coal chemical products, but also increases the utilization efficiency of raw coal material. The method provided by the invention solves the problem that low-rank coal is hard to gasify and utilize with a wet-process entrained-flow bed, lowers the consumption of raw material in the gasification process, reduces the emission of waste water, lowers the production of greenhouse gas in the process and achieves the purpose of efficient classified and quality-divided utilization of coal resources. |
