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.
Claims6
A deoxygenation catalyst useful in the conversion of bio-derived feedstocks, wherein said catalyst consists essentially of:
- a support, comprising a silica-alumina component, wherein said support has a mean pore diameter in a range of from 40 Å to 200 Å and a nitrogen surface area in a range of from 200 m2/g to 500 m2/g, and exhibits Raman spectral characteristics such that its Raman spectrum has at least one Raman peak within the Raman region of from 1300 cm−1 to 1500 cm−1;
- and
- a molybdenum component in an amount such that said catalyst comprises from 10 wt. % to 20 wt. % molybdenum, calculated as metal, regardless of its actual state, and based on the total weight of said catalyst, wherein said catalyst has a material absence of nickel and a material absence of cobalt, wherein said silica-alumina component of said support comprises from 2 wt. % to 15 wt. % of silica and from 85 wt. % to 98 wt. % alumina, wherein said material absence of nickel is less than 1 wt. % nickel, calculated as metal and based on the total weight of said catalyst, and wherein said material absence of cobalt is less than 1 wt. % cobalt, calculated as metal and based on the total weight of said catalyst.
