Claim:
1. A two-stage process for the conversion of solid particulate biomass material, the process comprising: (i) a first stage comprising the step of subjecting the solid particulate biomass material to a pyrolysis reaction in a first zone of a reactor to produce primary reaction products; (ii) a second stage comprising the step of subjecting at least part of the primary reaction products to a catalytic conversion reaction in a second zone of the reactor, in the presence of a catalyst, to produce secondary reaction products, wherein the first and second zones of the reactor are in fluid communication and further wherein the second zone of the reactor is positioned above the first zone of the reactor; and (iii) wherein the first and second zones each have an internal diameter and wherein the internal diameter of the second zone is less than the internal diameter of the first zone.
