The present invention relates to a process for treating a lignocellulosic biomass pretreated beforehand (), said process comprising the extraction of the free sugars from said pretreated biomass using an alcoholic or aqueous-alcoholic extraction solution (), so as to obtain a liquid phase enriched in free sugars, called liquor (), and a solid phase depleted in free sugars, called must ().

Process for treating lignocellulosic biomass

A process for the treatment of a gasoline containing sulfur compounds and olefins includes the following stages:

Method for producing gasoline with low sulphur and mercaptan content

The present invention concerns a method for processing a petrol containing sulfur and olefin compounds, comprising the following steps: a) a step of hydrodesulfurisation in the presence of a catalyst comprising an oxide support and an active phase comprising a metal from group VIB and a metal from group VIII, b) a step of separating the HS formed, c) a step of hydrodesulfurisation at a higher temperature than that of step a), with a hydrogen/feedstock ratio less than that of step a), and in the presence of a hydrodesulfurisation catalyst comprising an oxide support and an active phase consisting of at least one metal from group VIII, d) a step of separating the HS formed.

Method for producing a petrol with low sulfur and mercaptans content

The invention relates to a method for producing butadiene that is fed with a butanediol feedstock, with said method comprising at least:

Method for producing and purifying 1,3-butadiene

The invention relates to a process for producing butadiene from an ethanol feedstock comprising a step of converting ethanol into butadiene, a step of separating the reactants into a hydrated butadiene effluent, an impurities effluent and an ethanol-butadiene effluent, a separation step that separates the ethanol-butadiene effluent into a butadiene distillate and a contaminated reactants effluent, a step of purifying the butadiene by extractive distillation and an effluent treatment step.

Process for producing butadiene from ethanol integrated with extractive distillation

The invention relates to a method for producing 1,3-butanediene from a butanediol feedstock that includes:

Method for producing butadiene from butanediols

The invention relates to a process for producing butadiene from an ethanol feedstock, comprising a step of converting the ethanol into butadiene, a distillation step, a step of washing with water, a butadiene purification step comprising at least one section for separating the 1-butene by extractive distillation and a final distillation section fed with the topped butadiene distillate, separating at the top a purified butadiene effluent and at the bottom a butene residue, and an effluent treatment step.
