Adopting the patent technology of non-heat carrier and heat accumulating type revolving bed with medium and low-temperature pyrogenation invented by Shenwu Group, China Coal Pingshuo one million T/Y coal pyrogenation project was constructed at Pinglu Recycling Economy Park, Shouzhou, Shanxi, including one million tons coal pyrogenation, coal gas cooling and purification, PSA hydrogen purification by pyrogenous coal gas and the public and auxiliary facilities. All the hydrogen is transferred to the synthetic ammonia plant, and in addition to self consumption, all the desorption gas is transferred outside; and some of the resources within the plant area can be used to realize the optimized design and save the costs.
