hydrodeoxygenation process of loads from renewable sources with limited conversion to decarboxylation using a nickel and molybdenum catalyst

摘要

HYDRODEXYGENING PROCESS OF LOADS FROM RENEWABLE SOURCES WITH LIMITED DEVARBOXATION CONVERSION USING A NICKEL AND MOLIBDENE CATALYST. The invention relates to a hydrodeoxygenation process of loads from renewable sources with limited conversion to max. Decarboxylation / decarbonisation limited to a maximum of 10% using a supported or mass catalyst comprising an active phase consisting of at least one member of the group. VIB and at least one group VIII element, such elements being in sulfide form and the group VIII dometal atomic relationship (or metals) on group VIB metal (or metals), being strictly greater than O and less than 0,095, this process being applied at a temperature of between 120 and 450 ° C, a pressure of between IMPa and 10 MPa, an hourly space velocity of between 0.1 h1 and 10 h ~ -1 ~, and in the presence of a total amount of hydrogen mixed with the charge such that the hydrogen / charge ratio is between 50 and 3000 Nm3 hydrogen / m3 charge.
