PROCESS FOR THE HYDRODEOXYGENATION OF CHARGES FROM RENEWABLE SOURCES WITH LIMITED DECARBOXYLATION CONVERSION USING A NICKEL- AND- MOLYBNENUM BASED CATALYST

摘要

The invention relates to a process for the hydrodeoxygenation of feedstocks from renewable sources with a conversion by decarboxylation / decarbonylation limited to at most 10%, using a mass or supported catalyst comprising an active phase consisting of at least one group VIB element. and at least one element of group VIII, said elements being in sulphide form and the atomic ratio of the metal (or metals) of group VIII to metal (or metals) of group VIB being strictly greater than 0 and less than 0.095, said process being carried out at a temperature between 120 and 450 ° C, at a pressure of between 1 MPa and 10 MPa, at a space velocity of between 0.1 h-1 and 10 h-1 and in the presence of a total amount of hydrogen mixed with the feedstock such that the hydrogen / feed ratio is between 50 and 3000 Nm3 of hydrogen per cubic meter of feedstock.
