Abstract
A process for upgrading a bio-oil stream is disclosed. The process comprises discharging spent hydrotreating catalyst fines from a hydrotreating reactor. The hydrotreating catalyst fines comprise a metal from Group IVB, Group VB, Group VIB, Group VIIB, and Group VIII metals on an inorganic support. A bio-oil stream is reacted with hydrogen in the presence of the spent hydrotreating catalyst fines in a bio-oil reactor to produce an upgraded bio-oil stream. The spent hydrotreating catalyst fines can be characterized by a D90 particles size of about 1000 microns.

A process for upgrading a bio-oil stream comprising:
- reacting a bio-oil stream with hydrogen in the presence of hydrotreating catalyst fines comprising a metal from Group IVB, Group VB, Group VIB, Group VIIB, or Group VIII on an inorganic support in a reactor to produce an upgraded bio-oil stream, wherein the hydrotreating catalyst fines have a D90 particle size of about 1000 microns;
- and
- separating said spent hydrotreating catalyst from said upgraded bio-oil stream.
A process for upgrading a bio-oil stream comprising:
- reacting a bio-oil stream with hydrogen in the presence of spent hydrotreating catalyst fines comprising a metal from Group IVB, Group VB, Group VIB, Group VIIB, or Group VIII on an inorganic support in a reactor to produce an upgraded bio-oil stream, wherein the hydrotreating catalyst fines have D90 particles size of about 1000 microns in the reactor;
- and
- separating the spent hydrotreating catalyst from said upgraded bio-oil stream.
A process for upgrading a bio-oil stream comprising:
- reacting a bio-oil stream with hydrogen in the presence of spent hydrotreating catalyst fines comprising a metal from Group IVB, Group VB, Group VIB, Group VIIB, or Group VIII on an inorganic oxide support in a reactor to produce an upgraded bio-oil stream, wherein the reactor is operated at a temperature of about 300° C. (572° F.) to about 500° C.;
- and
- separating said spent hydrotreating catalyst from said upgraded bio-oil stream.
