Catalytic Production of Branched Small Alkanes from Biohydrocarbons

Squalane, C30 algae‐derived branched hydrocarbon, was successfully converted to smaller hydrocarbons without skeletal isomerization and aromatization over ruthenium on ceria (Ru/CeO2). The internal CH2CH2 bonds located between branches are preferably dissociated to give branched alkanes with very s...

Description
Summary:Squalane, C30 algae‐derived branched hydrocarbon, was successfully converted to smaller hydrocarbons without skeletal isomerization and aromatization over ruthenium on ceria (Ru/CeO2). The internal CH2CH2 bonds located between branches are preferably dissociated to give branched alkanes with very simple distribution as compared with conventional methods using metal‐acid bifunctional catalysts. If you want to hang out, you′ve gotta branch out, alkanes: Selective dissociation of internal CH2CH2 bonds located between branches in squalane proceeds over Ru/CeO2 without skeletal isomerization or aromatization, as compared to conventional methods using metal‐acid bifunctional catalysts. The small alkanes produced are suitable components for biobased liquid fuels because of their branched structures.
