Propane to olefins tandem catalysis: a selective route towards light olefins production

Abstract

Combining propane dehydrogenation with propylene metathesis in a single step yields mixtures of propylene, ethylene and butenes, important building blocks for the chemical industry. The open challenges and opportunities in the field are highlighted.

Atomic-scale changes of silica-supported catalysts with nanocrystalline or amorphous gallia phases: implications of hydrogen pretreatment on their selectivity for propane dehydrogenation

“… 6,7 Furthermore, the FCDh (fluidized catalytic dehydrogenation of propane) process, which uses a PtGa/Al 2 O 3 catalyst is currently at the initial phase of its industrial deployment. 8 …”

Linker micro-regulation of a Hofmann-based metal–organic framework for efficient propylene/propane separation

“…Propylene (C 3 H 6 ), produced by steam cracking, 1 catalytic cracking, 2 and other methods is significant in the petrochemical industry for the manufacture of polypropylene, plastics, and resins. However, its saturated counterpart, propane (C 3 H 8 ), has similar physicochemical properties and molecular size (C 3 H 8 : 6.80 × 4.20 × 4.60 Å; C 3 H 6 : 6.44 × 4.65 × 4.16 Å) and is inevitably co-produced during such processes, making the C 3 H 6 /C 3 H 8 separation a challenging task (Table S1 †).…”

Uncovering selective and active Ga surface sites in gallia–alumina mixed-oxide propane dehydrogenation catalysts by dynamic nuclear polarization surface enhanced NMR spectroscopy

“… 1,2 More recently, a PtGa/Al 2 O 3 catalyst has been developed for the use in the FCDh (fluidized catalytic dehydrogenation) process, which allows energy usage (and therefore the carbon footprint) of PDH to be reduced. 3 However, the role of platinum in PtGa catalysts is currently debated, ranging from a promoter of coordinately unsaturated Ga 3+ active sites, 4 to the active phase itself, such as site-isolated Pt atoms in metallic PtGa alloyed nanoparticles. 5 …”
