Abstract
A catalyst and process for the deoxygenation and conversion of bio-derived feedstocks. The catalyst comprises a silica-alumina support having specifically defined physical properties and a molybdenum component but a material absence of nickel. The process involves the processing of a bio-derived feedstock having an oxygen content to yield a conversion product having an exceptional distillation profile and physical properties and a substantially reduced oxygen content.
Claims16
A catalyst useful in the deoxygenation and conversion of bio-derived feedstocks, wherein said catalyst comprises:
- a support, comprising a silica-alumina component, wherein said support has a mean pore diameter in the range of from 40 Å to 200 Å and a nitrogen surface area in the range of from 200 m2/g to 500 m2/g;
- and
- a molybdenum component in an amount such that said catalyst comprises from 5 to 25 wt. % molybdenum, based on the total weight of said catalyst and said molybdenum as metal, regardless of its actual state, and wherein said catalyst has a material absence of nickel.
A catalyst useful in the deoxygenation and conversion of bio-derived feedstocks, wherein said catalyst consists essentially of:
- a silica-alumina support having from 2 to 15 wt. % of silica and from 85 wt. % to 98 wt. % alumina and a mean pore diameter in the range of from 40 A to 200 A and a nitrogen surface area in the range of from 200 m2/g to 500 m2/g;
- and
- molybdenum present in an amount in the range of from 5 to 25 wt. % molybdenum, based on the total weight of said catalyst and said molybdenum as metal, regardless of its actual state.
A process for deoxygenation and conversion of a bio-derived feedstock having an oxygen content, wherein said process comprises:
- contacting said bio-derived feedstock under suitable deoxygenation and conversion process conditions with a catalyst comprising a support comprising a silica-alumina component impregnated with molybdenum, wherein said support has a mean pore diameter in the range of from 40 Å to 500 Å and a nitrogen surface area in the range of from 200 m2/g to 500 m2/g, and wherein said catalyst comprises from 5 to 25 wt. % molybdenum, based on the total weight of said catalyst and molybdenum as metal, regardless of its actual state, and wherein said catalyst has a material absence of nickel and cobalt;
- and
- yielding a conversion product having a reduced oxygen content that is significantly reduced below said oxygen content of said bio-derived feedstock.
