Abstract
A method is disclosed for hydrodeoxygenation of a bio-oil over a catalyst bed in a hydrodeoxygenation reactor, the method including combining a two-phase diluent having a water dew point and a bio-oil at a bio-oil temperature that is from 50° F. less than to 50° F. more than the water dew point. The two-phase diluent includes a liquid phase and a vapor phase, where the liquid phase includes a hydrocarbon and the vapor phase includes hydrogen and water.
Claims19
A method for hydrodeoxygenation of a bio-oil over a catalyst bed in a hydrodeoxygenation reactor (“HDO reactor”), the method comprising
- combining a two-phase diluent having a water dew point of about 210° F. to about 350° F. and the bio-oil at a bio-oil temperature that is from 50° F. less than to 100° F. more than the water dew point, wherein the combining provides a diluted-bio-oil;
- and
- contacting the diluted bio-oil with the catalyst bed under hydrodeoxygenation conditions to provide a catalyst bed outlet product;
- wherein the two-phase diluent comprises a liquid phase and a vapor phase, the liquid phase comprising a hydrocarbon and the vapor phase comprising hydrogen and water.
A method for hydrodeoxygenation of bio-oils over a catalyst bed comprising the steps
- (a) providing a bio-oil;
- (b) providing a two-phase diluent wherein the two phases include a liquid comprising a hydrocarbon and a vapor phase comprising hydrogen and water;
- (c) combining the bio-oil with the two-phase diluent at a bio-oil temperature to provide a diluted bio-oil;
- and
- (d) hydrodeoxygenating the diluted bio-oil over the catalyst bed;
- wherein
- the two-phase diluent is characterized by a water dew point of about 210° F. to about 350° F.;
- and
- the bio-oil temperature is at most 50° F. below the water dew point of the two-phase diluent.
