Title:
PROCESS FOR UPGRADING OXYGEN CONTAINING RENEWABLE OIL
Document Type and Number:
WIPO Patent Application WO/2019/138002
Kind Code:
A1
Abstract:
The invention relates to a process for producing an upgraded renewable oil from renewable carbonaceous material(-s) comprising providing an oxygen containing renewable crude oil having an oxygen content in the range of 3.0 to 20 % by weight, a water content of less than 1.5 wt. %, a total acid number in the range from 5 to 80 mg KOH/g, a fraction of the oil having a boiling point below than 350 °C of less than 70 % by weight, and a residue fraction having a boiling point of more than 450 °C of at least 10 %by weight, pressurisingthe oxygen containing renewable crude oil to an operational pressure in the range 60 to 200 bar; adding and mixing hydrogen to the pressurized oxygen containing renewable crude oil,contacting the pressurized mixture with at least one heterogeneous catalyst contained in a first reaction zone at a temperature of 260 to 350 °C having a weight based hourly space velocity (WHSV) in the range 0.1 to 1 h-1 so as to produce a partially hydrogenated and deoxygenated oil,separating water, gas and optionally a low boiling fraction from the partially hydrogenated and deoxygenatedoil from the first reaction zone, heating the partially hydrogenated and deoxygenated oil from the first reaction zone to a temperature in the range 350 to 400 °C,contacting the partially hydrogenated and deoxygenated oil with at least one heterogeneous catalysts in a second reaction zone at a temperature of 350 to 400 °C at weight based hourly space velocity (WHSV) in the range 0.1 to 1.5 h-1, separating the product from the second reaction zone into a at least a gas fraction, a water fraction, a low boiling point renewable liquid hydrocarbon fraction and a high boiling point renewable liquid hydrocarbon fraction, contacting the low boiling point fraction from the second reaction zone with hydrogen and one or more heterogeneous catalysts at a temperature in the range 350 to 390 °C in a third reaction zone having a weight based space velocity in the range 0.1 to 1 h-1, thereby producing a first product stream and contacting the high boiling point oil fraction with hydrogen and one or more heterogeneous catalysts at a temperature in the range 360-420 °C in a fourth reaction zone having a weight based space velocity in the range 0.1 to 1 h-1, thereby producing a second product stream.
