The second phase gasification unit of Ningbo Wanhua Polyurethane Co., Ltd. uses coal as raw material and adopts the "multi-nozzle opposed water-coal slurry gasification technology" independently patented by East China University of Science and Technology. It is designed as a large-scale chemical production unit with an annual output of 80,000 tons of synthetic ammonia and 220,000 tons of methanol. It has two-stage deep sulfur-resistant conversion and an export CO index of 0.8-1.0%.
The conversion section of the unit uses QDB-03 catalyst in all stages and was started in October 2010. The operation results show that the QDB-03 catalyst has good conversion activity and activity stability, meeting the requirements of deep conversion process conditions for catalyst performance.
