1. A process for the continuous preparation of a powdered material having a calorific value greater than the calorific value of an initial biomass before steam cracking, comprising: a steam cracking stage, wherein the initial biomass subjected to the steam cracking stage is constituted of elements with a particle size class of between P16 and P100, having a moisture content of less than 27%, the initial biomass being directly subjected to a steam cracking treatment in the steam cracking stage at a temperature of from about 195° C. to about 215° C. for from about 5 minutes to about 30 minutes characterized by a severity factor in the steam cracking stage which is controlled by a computer based on a carbon content measured in an off-gas of the steam cracking stage to maximize a lower heating value of the powdered material.
