| 20090318740 | METHOD OF CONVERTING FEEDSTOCKS FROM RENEWABLE SOURCES TO GOOD-QUALITY DIESEL FUEL BASES USING A ZEOLITE TYPE CATALYST - The invention relates to a method of treating feedstocks from renewable sources in order to produce diesel fuel bases of excellent quality. The feedstocks used can be, for example, raw vegetable oils or such oils that have been previously subjected to a prerefining stage, animal fats, or mixtures of such feedstocks. The invention relates to a method allowing high diesel fuel base yields to be obtained from such feedstocks. | 12-24-2009 |
| 20090326290 | METHOD OF CONVERTING FEEDSTOCKS FROM RENEWABLE SOURCES TO GOOD-QUALITY DIESEL FUEL BASES USING A ZEOLITE CATALYST WITHOUT INTERMEDIATE GAS-LIQUID SEPARATION - The invention relates to a method of treating feedstocks from renewable sources without intermediate gas-liquid separation in order to produce diesel fuel bases of excellent quality. The feedstocks used can be raw vegetable oils or such oils that have been previously subjected to a prerefining stage, animal fats, or mixtures of such feedstocks. The invention relates to a method allowing high diesel fuel base yields to be obtained from such feedstocks. | 12-31-2009 |
| 20100163458 | METHOD OF CONVERTING EFFLUENTS OF RENEWABLE ORIGIN INTO FUEL OF EXCELLENT QUALITY BY USING A MOLYBDENUM-BASED CATALYST - The invention is concerned with a supported or unsupported catalyst comprising an active phase constituted by a sulfur-containing group VIB element, the group VIB element being molybdenum, and a hydrodeoxygenation process with a yield of hydrodeoxygenation product which is greater than or equal to 90% of charges from renewable sources using a catalyst according to the invention. | 07-01-2010 |
| 20100240942 | PROCESS FOR HYDRODEOXYGENATION OF FEEDS DERIVED FROM RENEWABLE SOURCES WITH LIMITED DECARBOXYLATION CONVERSION USING A CATALYST BASED ON NICKEL AND MOLYBDENUM - The invention concerns a process for hydrodeoxygenation of feeds derived from renewable sources with conversion by decarboxylation/decarbonylation limited to at most 10%, using a bulk or supported catalyst comprising an active phase constituted by at least one element from group VIB and at least one element from group VIII, said elements being in the sulphide form, and the atomic ratio of the metal (or metals) from group VIII to the metal (or metals) from group VIB being strictly more than 0 and less than 0.095, said process being carried out at a temperature in the range 120° C. to 450° C., at a pressure in the range 1 MPa to 10 MPa, at an hourly space velocity in the range 0.1 h | 09-23-2010 |
| 20110087059 | PROCESS FOR HYDROTREATMENT AND HYDROISOMERIZATION OF FEEDSTOCKS OBTAINED FROM A RENEWABLE SOURCE IMPLEMENTING A MODIFIED ZEOLITE - This invention describes a process for treatment of feedstocks obtained from a renewable source implementing a catalyst that comprises at least one hydro-dehydrogenating metal that is selected from the group that is formed by the metals of group VIB and group VIII of the periodic table and a substrate that comprises at least one zeolite that has at least one series of channels whose opening is defined by a ring with 8 oxygen atoms modified by a) at least one stage for introducing at least one alkaline cation that belongs to group IA or IIA of the periodic table, b) a stage for treating said zeolite in the presence of at least one molecular compound that contains at least one silicon atom, c) at least one stage of partial exchange of said alkaline cations by NH | 04-14-2011 |
| 20110094149 | METHOD OF HYDROTREATING FEEDS FROM RENEWABLE SOURCES WITH INDIRECT HEATING USING A CATALYST BASED ON MOLYBDENUM - The invention describes a method of treating feeds from renewable sources comprising a hydrotreatment stage comprising at least two catalytic zones in which the entry stream comprising said feed mixed with at least a part of a hydrotreated liquid effluent from stage b) is introduced into the first catalytic zone at a temperature comprised between 150 and 260° C., and the effluent from the first catalytic zone is then introduced, mixed with at least a part of a hydrotreated liquid effluent from stage b) and preheated, into the following catalytic zone or zones at a temperature comprised between 260 and 320° C., and a stage of separation of the effluent from the hydrotreatment stage permitting the separation of a gaseous effluent and a hydrotreated liquid effluent of which at least a part is recycled at the top of each catalytic zone, said method using, in at least the catalytic zone or zones following the first, a bulk or supported catalyst comprising an active phase constituted by a sulphidized group VIB element, the group VIB element being molybdenum. | 04-28-2011 |
| 20110098494 | METHOD OF HYDROTREATING FEEDS FROM RENEWABLE SOURCES WITH INDIRECT HEATING USING A CATALYST BASED ON NICKEL AND MOLYBDENUM HAVING A PARTICULAR ATOMIC RATIO - The invention describes a method of treating feeds from renewable sources comprising a hydrotreatment stage comprising at least two catalytic zones in which the entry stream comprising said feed mixed with at least a part of a hydrotreated liquid effluent from stage b) is introduced into the first catalytic zone at a temperature comprised between 150 and 260° C., and the effluent from the first catalytic zone is then introduced, mixed with at least a part of a hydrotreated liquid effluent from stage b) and preheated, into the following catalytic zone or zones at a temperature comprised between 260 and 320° C., and a stage of separation of the effluent from the hydrotreatment stage permitting the separation of a gaseous effluent and a hydrotreated liquid effluent of which at least a part is recycled at the top of each catalytic zone, said method using, in at least the catalytic zone or zones following the first, a bulk or supported catalyst comprising an active phase constituted by at least one group VIB element and at least one group VIII element, said elements being in sulphide form and the atomic ratio of the group VIII metal to the group VIB metal being strictly greater than 0 and less than 0.095. | 04-28-2011 |
