A process of treatment of carbonaceous material, such as wastewater sludge or organic waste, includes performing a thermal treatment of the carbonaceous material, thereby providing thermally treated carbonaceous material, cooling the thermally treated carbonaceous material, thereby providing cooled carbonaceous material, the cooling being performed using a vacuum cooling procedure, and performing a post-treatment of the cooled carbonaceous material, and at least one carbonaceous material degassing.

Process for anaerobic digestion of carbonaceous material

A waste treatment, pyrolysis and gasification and concerns an apparatus for syngas bio-methanation include a unit for pyrolysis/gasification receiving organic material, the unit for pyrolysis/gasification generating syngas, comprising at least one membrane reactor inside a liquid bath comprising at least one bacteria population, the membrane reactor comprising at least one hollow fiber in contact with the liquid bath, around which a biofilm is formed and into which the syngas from the unit for pyrolysis/gasification flows, so as to convert the syngas into methane. A method for bio-methanation of syngas comprising a step of providing syngas from a unit for pyrolysis/gasification to a membrane reactor inside a liquid bath comprising at least one suitable bacteria population, the membrane reactor comprising at least one hollow fiber in contact with the liquid bath, around which a biofilm is formed and into which the output syngas of the unit for pyrolysis flows, so as to convert the syngas into methane.

Apparatus and method for syngas bio-methanation

An apparatus for refractory organics conversion into biogas includes an anaerobic digester configured to be fed with organic material comprising refractory organics and to generate biogas and a digestate comprising at least a part of the refractory organics, wherein the apparatus comprises a device for a controlled partial oxidation of the refractory organics comprising an inlet configured to be fed with refractory organics and means configured to control the residence time of the refractory organics within the device for a controlled partial oxidation, so as to partially degrade refractory organics. A method for refractory organics conversion into biogas carried out using such an apparatus is also provided.
