Abstract: Disclosed is a method for preparing a material of plant origin rich in phenolic acids, including at least one metal, including: preparing a material of plant origin chosen from: aquatic plants; materials rich in tannins; materials rich in lignin; and obtaining a material of plant origin, rich in phenolic acids, in which the ratio of the intensity of the vibration band of the C═O bond of the COOH group and the intensity of each of the vibration bands the aromatic ring determined in FT-IR is between 0.5 and 4. The material of plant origin is brought into contact with an effluent including from 0.1 to 1000 mg/l of at least one metal, thus obtaining a material of plant origin rich in phenolic acids including from 1 to 30% by weight of at least one metal relative to the total weight of the material.

Abstract: To provide a method for producing propionaldehyde directly from glycerol with high yield, gasified glycerol is brought into contact with a silica-type regular mesoporous body. More specifically, gasified glycerol is supplied to a catalyst layer containing a regular mesoporous body while heating the catalyst layer at a temperature ranging from 200 to 800° C. in such a manner that a W/F value can fall within the range from 0.001 to 1000 g·min/ml inclusive wherein W represents an amount (g) of a catalyst and F represents a supply rate (ml/min) of supplied glycerol.

Abstract: A method of reducing a C—O bond to the corresponding C—H bond in a substrate, which could be a benzylic alcohol, allylic alcohol, ester or an ether bond beta to a hydroxyl group or alpha to a carbonyl group using a recyclable metal catalyst system. The recyclable catalyst system is also applicable to reducing a C═O bond to the corresponding C—OH bond and then C—H bond. These methodologies can be linked in one-pot to selective oxidation and depolymerizations of aromatic polyols such as lignin.
