Process of treating carbonaceous material and apparatus therefor

A process for processing a carbonaceous material, the process comprising:

• delivering the carbonaceous material to a first reactor;
• delivering a catalyst in the form of hot sand or other solid media in the form of sand to the first reactor, wherein the catalyst is delivered through a sand distribution assembly comprising a plurality of inputs into the first reactor, the plurality of inputs being controlled through adding fluidized air to the sand distribution assembly to decreases a density in a riser chamber and move the catalyst into the plurality of inputs;
• processing the carbonaceous material at a first temperature within the first reactor to decompose and/or devolatilise at least a portion of the carbonaceous material;
• delivering an output from the first reactor to a secondary reactor for thermal destruction of a portion of the output;
• the secondary reactor having a second temperature that is higher than the first temperature.
