<p>The invention relates to a method for producing a biobriquette from residual biomass of agricultural, agroindustrial and forest origin, and to a biobriquette produced by means of said method. Said method basically consists in: taking a representative sample and performing the physicochemical characterisation thereof, performing a first conditioning operation, performing a second conditioning operation, performing a grinding operation and a final screening operation, agglomerating the conditioned biomass, performing the pressing operation and finally curing the previously pressed biobriquette. The second conditioning consists of a roasting step and is carried out in a rotary reactor with a horizontal axis, in a non-pressurised environment, which lets in a small amount of air and does not require any external agent to inert the atmosphere wherein the process is carried out. The heating speed, the heating temperature and the period of residence at said latter temperature will depend on the type of residue and on other variables, the preferred values being: a heating speed of 20°C/min, a temperature of 270°C, and a period of residence of 40 minutes.</p> |
