Haffner Energy

A method for producing a synthesis gas from an organic material with a moisture content of less than 20%. A first step for carrying out the thermolysis of the organic material and a second, separate step for the gasification (ii) of the thermolysed organic material. The thermolysis step is carried out by increasing the temperature of the raw material up to an end temperature higher than 150&#xb0; C. and lower than 1400&#xb0; C.; &#x2014;the thermolysis step (i) is carried out in a controlled gas atmosphere in which the quantity of oxygen supplied is less than 20% of the quantity of oxygen required for the stoichiometric combustion of the organic raw material; &#x2014;the thermolysis gas obtained in the thermolysis step is conveyed to a purification step (iii) for removing undesirable elements.

Method for producing a synthesis gas

A thermolysis device for supplying heat energy at a temperature of between 80&#xb0; C. and 700&#xb0; C. and capable of adjusting the temperature inside a chamber including a raw material supply inlet, a thermolysis gas outlet, and an outlet for the solid or liquid materials from the thermolysis reaction. The chamber encloses at least one plate, separating the chamber into a top portion and a bottom portion, and at least one transfer element. The transfer element and/or the plate is mounted so as to rotate about an axis, the raw material supply inlet is placed above the plate, thus defining a first point for a raw material to drop onto the plate.
