By 6 years of researching, we successfully developed the technology of producing 20.4% of lightweight, 9.2% of petrol gas and 70.4% of coke from low quality lignite, by the State invention patent technology of catalytic low temperature thermal cracking method. After simple process, the lightweight fuel oil could be used to substitute diesel oil, the petrol gas could be used to substitute natural gas and the coke is badly needed by the market. Since the reserve of low quality lignite of our country is huge, the price is less than 200 Yuan/ton. The lightweight fuel oil, petrol gas and coke produced by the catalytic low temperature thermal cracking method will gain huge economic benefits.
