Method for processing liquefied materials

Abstract

There is provided a process for hydrotreating a liquid oil stream; wherein the liquid oil stream is a thermochemical decomposition oil stream; the process comprising: (i) a hydrotreatment step comprising hydrotreating the liquid oil stream in a fixed bed reactor at a temperature of less than 250° C., wherein the fixed bed reactor comprises a hydrotreatment catalyst; and (ii) an in-situ catalyst regeneration step such that one or more ammonium salts deposited on the hydrotreatment catalyst are removed from the hydrotreatment catalyst, wherein the in-situ catalyst regeneration step comprises heating the hydrotreatment catalyst with a flushing gas, or mixtures or a flushing gas and oil.
