Method and apparatus for converting organic material

A method for converting an organic material feed into a hydrocarbon fuel product, comprising the steps of:

• pressurizing said organic material being in a slurry to a pressure above 225 bar,
• heating said organic material in said slurry to a temperature above 200° C. in the presence of a homogeneous catalyst comprising a compound of at least one element of group IA of the periodic table of elements, wherein the method further comprises the steps of:
• contacting said organic material in said slurry with a heterogeneous catalyst in a reactor, the heterogeneous catalyst comprising a compound of at least one element of group IVB of the periodic table and/or alpha-alumina assuring that said slurry has initially a pH value of above 7, and maintaining the pH value of said slurry containing said organic material in the range 7-14 and,
• re-circulating at least a part of the slurry exiting the reactor by mixing it into the slurry comprising organic material prior to this entering the reactor, and wherein the concentration of said organic material is at least 5% by weight, the conversion of said organic material is at least 90%, and said hydrocarbon fuel product comprises an oil with at least 50% of the feed carbon content,
• pre-treating the slurry at a pressure of 4-15 bar at the temperature of 100-170° C. for a period of 0.5-2 hours, and wherein the step of pre-treating comprises the step of adding additives to the slurry comprising said organic material, and wherein the step of pre-treating comprises the step of adjusting the pH of said slurry comprising said organic material to above 7.
