In December 2009, the first phase of the annual production of 360,000 tons of methanol unit of Xinneng Phoenix (Tengzhou) Energy Co., Ltd. was successfully completed. The unit uses the "Texaco" water-coal slurry pressurized gasification unit, a sulfur-resistant conversion gas distribution process engineering, and a conversion pressure of up to 6.0Mpa or more, with a water/gas ratio of 1.0-1.1. Because the water/gas and bed hot spot temperatures are high, and the hydrogen sulfide content of the feed gas is low, as low as 700PPm, the problem of catalyst desulfurization has always been the most concerned issue for the plant. The operation results show that the QDB-03 catalyst has a high resistance to low sulfur, and there has been no catalyst desulfurization in the nearly two years of use, which affects the catalyst activity.
