Development of an efficient catalyst for dehydrogenation of alkanes
Dehydrogenation of alkane with developed catalyst.
Invention Summary:
Olefins (alkenes) are key intermediates in the production of fuels and many commodity chemicals. Alkanes, and particularly light linear alkanes, are increasingly abundant but of limited value. The dehydrogenation of alkanes is therefore an economically very attractive...
