The reporter learned from the Northwest Institute of Chemical Technology last week that an RSB-M high pressure, high vapor pressure, sulfur-resistant shift catalyst suitable for coal-water slurry pressure gasification processes in the coal chemical industry has been successfully applied in large chemical companies and passed Shaanxi Provincial Department of Science and Technology organized inspection and acceptance.
Experts believe that the Northwest Research Institute of Chemical Industry uses special carriers and preparation processes. The independently developed RSB-M sulfur-tolerant shift catalyst is suitable for the process of coal-water-slurry/multicomponent slurry pressurization and gasification. It has good low-temperature conversion activity and is easily vulcanized. High carbon monoxide (CO) conversion, strength and stability advantages. Its activity and anti-hydration performance are significantly better than those of similar catalysts at home and abroad, reaching the international advanced level and providing strong technical support for China's coal chemical industry.
According to Fang Genxiang, deputy chief engineer of Northwest Research Institute of Chemical Industry, RSB-M high-pressure, high-water-vapor and sulfur-tolerant shift catalysts were started from carrier research in 2002. After laboratory research, catalyst amplification preparation, 1200-hour plant sidestream test and industrial trial production , Overcoming key technical challenges in catalyst preparation, and finally succeeded in industrial applications. The project was listed as a major scientific and technological innovation special fund project in Shaanxi Province in 2005.
It is understood that the RSB-M catalyst developed by the Northwest Research Institute of Chemical Industry has formed a production capacity of 500 tons per year. From February 2006 to the present, Shaanxi Weihe Coal Chemical Group Co., Ltd., which has introduced the Texaco coal-water slurry pressure gasification plant in the United States, conducted two industrial trial evaluations and achieved success. RSB-M catalyst in the dehydration 300,000 tons / year ammonia conversion plant conversion section conditions harsh zero shift converter filling operation results show that the converter hot spot temperature is stable, the export CO content is lower (2.42% ~ 4.9%), CO conversion rate Above 85%, it fully meets the process requirements. The catalyst particles remain intact and have good activity and hydration resistance.
