Abstract
The present disclosure provides a catalyst composition for conversion of biomass to crude bio oil. The composition comprises at least one metal compound, at least one support and at least one stabilizing/solubilizing agent. Also disclosed are processes for the preparation of catalyst composition, and hydrothermal conversion of biomass to crude bio oil.
Claims24
A catalyst composition for conversion of biomass to crude bio oil;
- said composition comprising:
- i. at least one metal in an amount of 0.1 to 15 wt. %, wherein the metal is selected from the group consisting of group Ib, group IIb metals, group IVb metals, group Vb metals, group VIb metals, group VIIb metals, group VIII metals and noble metals;
- ii. at least one support in an amount of 30 to 96 wt %;
- and
- iii. at least one solubilizing agent in an amount of 4 to 50 wt. %, said solubilizing agent selected from the group consisting of ammonia solution, piperidine, pyrrolidine, morpholine, piperazine hydrate, 2-methylcyclohexyl amine, cyclohexylamine and hexamethyleneimine.

A process for the preparation of a catalyst composition having at least one metal in an amount of 0.1 to 15 wt. %;
- at least one support in an amount of 30 to 96 wt %;
- and at least one solubilizing agent in an amount of 4 to 50 wt. %, said process comprising the following steps:
- a. obtaining at least one support;
- b. preparing at least one dispersion containing at least one metal or metal compound, said metal compound comprises a metal selected from the group consisting of group Ib metals, group IIb metals, group IVb metals, group Vb metals, group VIb metals, group VIIb metals, group VIII metals and noble metals;
- c. adding at least one solubilizing agent to one or more of said at least one dispersion/s;
- d. obtaining a mixture of said at least one dispersion, wherein the one or more of said at least one dispersion/s comprises said at least one solubilizing agent;
- e. impregnating said mixture in said support to obtain a metal impregnated support;
- and
- f. drying the metal impregnated support followed by calcining and reducing to obtain the catalyst composition.
