Abstract:
1. A process for transforming heavy carbonaceous material comprising lignocellulosic biomass, said process comprising the following steps: a) a stream of said biomass in the form of initial solid fragments with a characteristic dimension in the range of 1 to 20 mm is introduced into a liquid L b) said liquid/solid mixture undergoes a maturation step at a temperature in the range 250° C. to 320° C. for a residence time of at least 10 minutes, to obtain a mixture of solid heat-treated fragments in a liquid L c) said solid heat-treated fragments mixed with at least a fraction of liquid L d) at least a fraction of said suspension of solids undergoes partial entrained bed oxidation (PDX) to produce a synthesis gas (SG).
