Abstract
Feedstock originating from renewable sources is converted to hydrocarbons in diesel fuel distillation range by contacting with a supported catalyst comprising VIII group metal/metals, whereby the consumption of hydrogen is decreased.
Claims28
A method for the selective manufacture of hydrocarbons suitable for diesel fuel pool, which comprises carrying out a decarboxylation/decarbonylation reaction by bringing a feedstock comprising C8-C24 fatty acids, derivatives of C8-C24 fatty acids, or combinations thereof, and optionally a solvent or a mixture of solvents, into contact with a heterogeneous elemental metal catalyst containing one or more Group VIII metals selected from platinum, palladium, nickel, iridium, ruthenium and rhodium on a support selected from oxides, mesoporous materials, carbonaceous supports and structured catalyst supports, at a temperature of 200-400° C. and under a pressure from 0.1 MPa to 15 MPa, to yield as a product hydrocarbons.
The method according to claim1, wherein the elemental metal catalyst contains rhodium.
