NOVELTY - Titanium dioxide based sulfur recovery catalyst is composed of 80-90 pts. wt. porous oxide having particle diameter of 150-200 mu m, 10-15 pts. wt. graphene, 5-8 pts. wt. iron oxide, 4-6 pts. wt. manganese dioxide, where porous oxide consists of 20-30 pts. wt. activated alumina, 60-80 pts. wt. titanium dioxide and 40-50 pts. wt. silica. USE - Titanium dioxide based sulfur recovery catalyst. ADVANTAGE - The titanium dioxide based sulfur recovery catalyst reduces cost of catalyst under hydrolysis activity of organic sulfur and antioxidant capacity and improves quantitive catalyst of catalytic conversion efficiency. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing titanium dioxide based sulfur recovery catalyst, which involves mixing porous oxide, graphene, sulfate and manganese sulfate, active alumina, titanium dioxide and silicon dioxide and dissolving in water to prepare ferric sulfate solution and manganese sulfate solution, dispersing graphene in mother liquor solution ultrasonically then adding porous oxide uniformly, mixing solution under continuous ultrasonic action of dropping copper sulfate solution to prepare manganese sulfate solution, mixing manganese sulfate solution and ferric sulfate solution, after finishing dripping, adding ammonium hydrogen carbonate into solution then filtering precipitate and washing by using de-ionized for 3-5 times, after washing precipitate at 80-120 degrees C for 35-50 minute, and drying at 480-530 degrees C for 2-4 hours to obtain finished product of catalyst.
