A propane dehydrogenation plant with an annual production of 600,000 tonnes was put into operation in the county-level city Taixing, east China's Jiangsu Province, May 13, 2023. /China Construction Industrial and Energy Engineering Group
Chinese scientists have made an achievement in the field of chemical engineering, laying the foundation for a new process of propane dehydrogenation, according to Tianjin University on Friday.
Propylene is an important raw material for the manufacture of plastic products, medical supplies, automotive supplies and building materials, which plays an important role in the global petrochemical industry.
Direct propane dehydrogenation is an attractive technology for propylene production, but the reaction process absorbs a lot of heat and produces high carbon dioxide emissions.

The research team from the university tested thousands of catalysts and discovered the influence of catalyst structure on propane conversion.
The team also broke through technical limitations of the common process with direct propane dehydrogenation.
Compared with the common process, the reaction temperature the team proposed can be reduced by 30 to 50 degrees Celsius, and the energy consumption can be reduced by 20 to 30 percent, which is expected to reduce carbon dioxide emissions greatly.
The study was published in the journal Science on Thursday.
