A method for processing carbonaceous material in a reactor. Carbonaceous material, such as sawdust, plant residues from forestry or agricultural processes, municipal solid waste and refuse derived fuel, is fed into the riser section (10) of a reactor (10-15) in which it is contacted with inorganic particulate material and reactor walls at an elevated temperature essentially in the absence of oxygen in order to convert the carbonaceous material at least mainly into gaseous processed products, whereby a gas phase is obtained, containing fluidization gas and processed products. According to the invention a dense suspension is formed into the riser space (10) of the reactor, containing based on the particle number 7x108 to 3x1011 particles/m3 (about 2x107-1x1010 particles/ft3), and the mass ratio between the particulate matter bringing heat into the reactor and the carbonaceous material is in the range of 1:1 to 10:1. By the invention, the mixing of the heat transfer medium and the feed is improved, and coarser and less uniform feed can be used than conventionally.
