Propane Dehydrogenation (PDH)

Propane Dehydrogenation (PDH) is a petrochemical process in the production of propylene from propane which is the second most important starting product in the petrochemical industry after ethylene. A PDH is a catalytic technology (CATOFIN: fixed-bed type of ABB Lummus and OLEFLEX: moving-bed type of UOP) utilised for the conversion of propane into propylene, and various catalysts have been developed to increase the propylene yield over recent decades (monometallic Pt nanoparticles).

Reference Definition by Wikipedia: Propane Dehydrogenation (PDH) converts propane into propene and by-product hydrogen. The propene from propane yield is about 85 m%. Reaction by-products (mainly hydrogen) are usually used as fuel for the propane dehydrogenation reaction. As a result, propene tends to be the only product, unless local demand exists for hydrogen. This route is popular in regions, such as the Middle East, where there is an abundance of propane from oil/gas operations. In this region, the propane output is expected to be capable of supplying not only domestic needs, but also the demand from China, where many PDH projects are scheduled to go on stream. However, as natural gas offerings in the United States are significantly increasing due to the rising exploitation of shale gas, propane prices are decreasing.
