In the beginning of November, the SD paraffin hydrogenation catalyst independently developed by the China Petroleum and Petrochemical Research Institute was successfully used in the 200,000 tons/year high-pressure wax hydrogenation unit of Fushun Petrochemical. The No.58 full-refinery wax product produced by the device, Saybolt color 30, and light stability 3, all the indicators have reached the requirements of the technical agreement indicators, and the product properties all meet the Fushun petrochemical paraffin product factory requirements.
In 2010, after the relocation of the No. 1 Oil Plant of Fushun Petrochemical Company to the No. 2 Oil Plant, a 200,000-ton/year high-pressure wax hydrogenation unit replaced the hydrogenation catalyst. According to the characteristics of Fushun Petrochemical high-pressure paraffin wax and microcrystalline wax hydrogenation, Daqing Chemical Research Center of Petrochemical Institute optimized and improved the preparation process of SD paraffin wax hydrogenation catalyst so that the prepared catalyst can be used under conditions of high airspeed and low hydrogen to oil ratio. Quality meets requirements. In September 2012, a 200,000-ton/year high-pressure wax hydrogenation unit completed the relocation of the plant. In October, the catalyst loading and successful start-up were completed.
In 2005, Fushun Petrochemical Company built the world's largest and only domestic high-pressure paraffin/microcrystalline wax hydrogenation unit. The hydrogenation catalyst has been used in the petrochemical hydrogenation catalyst developed by the petrochemical industry and achieved 54#, 56#, and 58. #, 60 #, 64 #, 66 # paraffin and 70 # microcrystalline wax switching production, product quality to the United States FDA food grade paraffin wax quality standards.
