Producing middle distillates e.g. diesel from feedstock from renewable sources comprises hydrotreating the feedstock with hydrotreatment catalyst and hydroisomerization of obtained effluent with hydroisomerization catalyst

摘要

Producing middle distillates from at least one feedstock from renewable sources comprises hydrotreating the feedstock with at least a hydrotreatment catalyst at a temperature of 120-450[deg] C, at a pressure of 1-10 MPa, and at a hourly space velocity of 0.1-10 hours - 1and in the presence of hydrogen/feedstock ratio of 50-3000 Nm 3and hydroisomerization of obtained effluent with at least one hydroisomerization catalyst at a temperature of 120-450[deg] C, at a pressure of 1-10 MPa and at a hourly space velocity of 0.1-10 hours - 1and in the presence of hydrogen/feedstock ratio of 50-3000 Nm 3. Producing middle distillates from at least one feedstock from renewable sources comprises: hydrotreating the feedstock with at least a hydrotreatment catalyst at a temperature of 120-450[deg] C, at a pressure of 1-10 MPa, and at a hourly space velocity of 0.1-10 hours - 1and in the presence of hydrogen/feedstock ratio of 50-3000 Nm 3of hydrogen/m 3of feedstock; and hydroisomerization of obtained effluent with at least one hydroisomerization catalyst at a temperature of 120-450[deg] C, at a total pressure of 1-10 MPa and at a hourly space velocity of 0.1-10 hours - 1and in the presence of hydrogen/feedstock ratio of 50-3000 Nm 3of hydrogen/m 3of feedstock, where the catalyst, comprises, in the oxide form, at least one metal from group VIB and/or at least one metal from group VIII of the periodic table, present in the form of at least one polyoxometalate of formula (H hX xM mO y)(q-), the polyoxometalate is present within an oxide based mesostructured matrix of at least one element Y1 comprising silicon, aluminum, titanium, zirconium, gallium and/or cerium, the matrix has a pore size of 1.5-50 nm and amorphous wall thickness of 1-30 nm, and the catalyst is sulfurized prior to use in the process. X : P, Si, B, Ni or Co; M : one or more element comprising Mo, W, Ni or Co; h : 0-12; x : 0-4; m : 5-12 or 18; y : 17-72; and q : 1-20.
