    摘要： Process for preparing a catalyst containing an active phase based on a group VIII metal and a porous support, comprising the following steps: bringing said support into contact with an organic compound comprising at least oxygen and/or nitrogen; bringing the porous support into contact with a solution containing a precursor of the active phase comprising a group VIII metal; drying the catalyst precursor at a temperature of less than 200° C. so as to obtain a dried catalyst precursor; calcining the dried catalyst precursor at a temperature of between 200° C. and 1100° C. under a stream of inert gas and/or of oxidizing gas, it being understood that the velocity of said gas stream, defined as the mass flow rate of said gas stream per volume of catalyst per hour, is greater than 1 litre per gram of catalyst and per hour.

    摘要： The invention concerns a process for the transformation of lignocellulosic biomass or cellulose into mono- or poly-oxygenated compounds, in which the lignocellulosic biomass or the cellulose is brought into simultaneous contact with a catalytic system comprising a combination of one or more homogeneous catalysts and one or more heterogeneous catalysts, in the same reaction chamber, in the presence of at least one solvent, said solvent being water alone or as a mixture with at least one other solvent, in a reducing atmosphere, and at a temperature in the range 80° C. to 250° C. and at a pressure in the range 0.5 MPa to 20 MPa.

    摘要： A process for the transformation of a feed of at least one sugar into 5-hydroxymethylfurfural, contacting the feed with one or more organic catalysts in the presence of at least one solvent, said solvent being water or an organic solvent, alone or as a mixture, at a temperature in the range 30° C. to 200° C., and at a pressure in the range 0.1 MPa to 10 MPa, in which said organic catalysts are selected from compounds from the thiourea family with general formula R1NH—C(═S)—NHR2, in which the groups R1 and R2 are aromatic groups optionally having a heteroatom, linear or branched alkyl groups, which may or may not be cyclic, and alkyl groups with at least one heteroatom, which may be linear or branched, which may or may not be cyclic, said groups R1 and R2 possibly being substituted or unsubstituted and which may be identical or different.
