On July 23, 2008, QDB-04 catalyst was successfully applied in the 400,000-ton methanol unit of Shaanxi Shenmu Chemical Industry Co., Ltd.

On June 3, 2008, QDB-04 catalyst was successfully used in the second phase of 100,000 tons of methanol in Shanxi Fengxi Linyi Branch.

The QDB series of new sulfur-tolerant shift catalysts developed by Qingdao Lianxin Chemical Co., Ltd. have excellent catalytic activity, strength and stability and other properties,

Due to the increasing shortage of oil resources, my country's coal chemical industry has entered a rapid development stage,

On February 26, 2008, QDB-03/QDB-04 catalyst was successfully applied in the dual-structure 180,000-ton synthetic ammonia and 300,000-ton urea unit of Yankuang Lunan Fertilizer Plant.

In January 2007, QDB series catalysts and the new pulverized coal gasification low water/gas ratio sulfur tolerant shift technology were successfully applied in the world's first pulverized coal gasification low water/gas sulfur tolerant shift ammonia production unit - Guangxi Liuzhou Chemical Industry Company, filling the gap of pulverized coal gasification.
