Abstract

A process for converting a solid biomass material is provided. The solid biomass material is contacted with a catalytic cracking catalyst at a temperature of more than 400° C. in a riser reactor to produce one or more cracked products. The riser reactor is an external riser reactor with a curve and/or low velocity zone at its termination and wherein a part of the catalytic cracking catalyst has deposited in the curve and/or low velocity zone.

First claim

What is claimed is:

1. A process for converting a solid biomass material, comprising
contacting the solid biomass material with a catalytic cracking catalyst at a temperature of more than 400° C. in a riser reactor to produce one or more cracked products, wherein the riser reactor is an external riser reactor with a curve and/or low velocity zone at its termination and wherein a part of the catalytic cracking catalyst has deposited in the curve and/or low velocity zone.

2. The process of claim 1 wherein the solid biomass material is fed to the riser reactor as a mixture of solid biomass material and steam.

3. The process of claim 1 wherein the riser reactor comprises a riser reactor pipe having a diameter that increases in a downstream direction.

4. The process of claim 1 wherein a fluid hydrocarbon feed is fed into the riser reactor.

5. The process of claim 1 wherein the solid biomass material is supplied at the bottom of the riser reactor.

6. The process of claim 1 wherein the riser reactor comprises a bottom section and a riser reactor pipe and wherein the bottom section has a larger diameter than the riser reactor pipe.

7. The process of claim 1 wherein the external riser reactor comprises a riser reactor pipe, which riser reactor pipe is curved at the end or which riser reactor pipe has a low velocity zone at its upper end.

8. The process of claim 7 wherein the riser reactor pipe is connected via the curve or low velocity zone to a downstream crossover pipe.

9. The process of claim 1 wherein the fluid hydrocarbon feed is introduced to the riser reactor at a location where the solid biomass material already had a residence time in the range from equal to or more than 0.1 seconds to equal to or less than 1 seconds.

10. The process of claim 1 wherein the ratio between the residence time for the solid biomass material to the residence time for the fluid hydrocarbon feed (residence solid biomass:residence hydrocarbon ratio) lies in the range from equal to or more than 1.01:1 to equal to or less than 2:1.

11. The process of claim 1 wherein the solid biomass material is introduced to the riser reactor at a location with temperature T 1 and the fluid hydrocarbon feed is introduced to the riser reactor at a location with temperature T 2 and temperature T 1 is higher than temperature T 2 .

12. The process of claim 1 wherein the one or more cracked products is/are subsequently fractionated to produce one or more product fractions.

13. The process of claim 12 wherein the one or more product fractions obtained by fractionation are subsequently hydrodeoxygenated to obtain one or more hydrodeoxygenated products.

14. The process of claim 12 wherein the one or more product fractions are blended with one or more other components to prepare a biofuel and/or a biochemical.

15. The process of claim 13 wherein the one or more hydrodeoxygenated product fractions are blended with one or more other components to prepare a biofuel and/or a biochemical.
