Clariant supplies catalysts for Xuzhou Heidi propane dehydrogenation plant

KAYNE Chemical News On December 8, specialty chemicals manufacturer Clariant announced that it has signed an agreement with Xuzhou Haiding Chemical Technology Co., Ltd. to work with its technology partner CB & amp; I to develop a customized CATOFIN catalyst, And build a propane dehydrogenation (PDH) unit. The project includes the technology licensing and engineering design of the unit to be built in Pizhou, Jiangsu Province, China.

The propylene design capacity at Xuzhou Haiding Plant is 600,000 tons / year. The plant will be based on Clariant's CATOFIN catalytic dehydrogenation technology with Clariant's CATOFIN catalyst and heating material (HGM).

CATOFIN is a proven dehydrogenation catalyst that can be used to produce light olefins such as propylene, isobutylene and other olefins. HGM is a patented metal oxide material that can be packed with a catalyst to increase the selectivity and throughput of CATOFIN units. In order to maximize propane conversion and obtain high yields of propylene, the process is operated at reactor pressures and temperatures that are most favorable to thermodynamics and catalysts with high selectivity are used. Among the proven technologies in the market today, Catofin is able to achieve maximum conversion rates and maximum selectivity with its optimized operating conditions.

The 9 global propane dehydrogenation plants using CATOFIN technology have all been successfully put into operation, with an annual output of more than 4.5 million tons of propylene. Factories that use CATOFIN technology typically operate more than 110% of their design capacity, and the factory-line rate approaches 98%.
