## Abstract

The present invention provides a process for producing liquid hydrocarbon products from a feedstock comprising at least one of a solid biomass-containing feedstock and a solid biomass-derived feedstock and in the range of from 50 to 15000 ppmw of chlorides, said process comprising the steps of: a) incorporating a chloride trap material into said feedstock to provide a combined feedstock/chloride trap material; b) densifying the combined feedstock/chloride trap material to form densified feed in the form of pellets or briquettes; c) contacting said densified feed with a hydropyrolysis catalyst composition and molecular hydrogen in a hydropyrolysis reactor vessel at a temperature in the range of from 350 to 600° C. and a pressure in the range of from 0.50 to 7.50 MPa to produce a product stream comprising a deoxygenated hydrocarbon product, H2O, H2, CO2, CO, C1-C3 gases, char and catalyst fines; and d) removing all or a portion of said char and catalyst fines from said product stream.

## Claims

### Claim 1

A process for producing liquid hydrocarbon products from a feedstock comprising at least one of a solid biomass-containing feedstock and a solid biomass-derived feedstock and in the range of from 50 to 15000 ppmw of chlorides, the process comprising:
a) incorporating a chloride trap material into the feedstock to provide a combined feedstock/chloride trap material;
b) densifying the combined feedstock/chloride trap material to form a densified feed in the form of pellets or briquettes;
c) contacting the densified feed with a hydropyrolysis catalyst composition and molecular hydrogen in a hydropyrolysis reactor vessel at a temperature in the range of from 350 to 600° C. and a pressure in the range of from 0.50 to 7.50 MPa to produce a product stream comprising a deoxygenated hydrocarbon product, H2O, H2, CO2, CO, C1-C3 gases, char and catalyst fines; and
d) removing all or a portion of the char and catalyst fines from the product stream.

### Claim 2 (depends on 1)

The process according to claim 1, wherein the densified feed is in the form of material with a longest length no more than 5 mm.

### Claim 3 (depends on 1)

The process according to claim 1, wherein the densified feed is subjected to a size reduction step before being provided to the hydropyrolysis reactor vessel.

### Claim 4 (depends on 1)

The process according to claim 1, wherein the feedstock comprises municipal solid waste.

### Claim 5 (depends on 1)

The process according to claim 1, wherein the feedstock comprises at least one of paper and cardboard.

### Claim 6 (depends on 1)

The process according to claim 1, wherein the feedstock comprises a chlorine-containing plastic.

### Claim 7 (depends on 1)

The process according to claim 1, wherein the feedstock comprises in the range of from 500 to 8000 ppmw of chlorides.

### Claim 8 (depends on 1)

The process according to claim 1, wherein the chloride trap material comprises at least one of oxides, hydroxides, carbonates and bicarbonates of alkali and alkaline earth metals.

### Claim 9 (depends on 1)

The process according to claim 1, wherein after removal of the char and cooling, the deoxygenated hydrocarbon product together with the H2, CO, CO2, H2O, and C1-C3 gases from the hydropyrolysis step are contacted with one or more catalyst compositions in a hydroconversion reactor.

### Claim 10 (depends on 8)

The process according to claim 8, wherein the chloride trap material comprises at least one of NaHCO3, Na2CO3, Ca(OH)2, CaO, MgO and CaCO3.
