  • Patent number: 11718799
    Abstract: The invention relates to a catalytic process for upgrading a renewable crude oil produced from biomass and/or waste comprising providing a renewable crude oil and pressurizing it to a pressure in the range in the range 60 to 150 bar, contacting the pressurized renewable crude oil with hydrogen and at least one heterogeneous catalyst contained in a first reaction zone at a weight based hourly space velocity (WHSV) in the range 0.1 to 2.0 h?1 and at a temperature in the range of 150° C. to 360° C.
    Type: Grant

  • Patent number: 11578275
    Abstract: The invention relates to producing upgraded renewable oil. Renewable crude oil is provided whose oxygen content, water content, and total acid number are within predetermined ranges. Respective fractions of the oil have boiling points below 350° C. and above 450° C. After the oil is pressurized, and hydrogen is added, the mixture is heated and contacted with a heterogeneous catalyst in a first reaction zone with weight based hourly space velocity (WHSV) of 0.1 to 1 h-1. The resultant partially hydrogenated and deoxygenated oil is further heated and contacted with a heterogeneous catalyst in a second reaction zone at WHSV of 0.1 to 1.5 h-1. Low and high boiling point liquid hydrocarbon fractions of the product of the second reaction zone are sent to third and fourth reaction zones, respectively, to be contacted with hydrogen and a heterogeneous catalyst under respective heating conditions and WHSV of 0.1 to 1 h-1.

  • Patent number: 11459510
    Abstract: The invention relates to a process for producing an upgraded renewable oil from renewable carbonaceous material(-s) comprising providing a low sulphur oxygen containing renewable crude oil having a sulphur content of less than 0.5 wt % and an oxygen content from about 2.0 wt to about 20 wt %, pressurising the low sulphur oxygen containing renewable crude oil to an operational pressure in the range 20 to 200 bar, adding and mixing hydrogen to the pressurized low sulphur oxygen containing crude oil, heating the oil to an operational temperature in the range 180-410° C. in one or more steps, contacting said oil with at least one heterogeneous catalyst contained in a first reaction zone, contacting the effluent from said first reaction zone with at least one heterogeneous catalyst contained in a second reaction zone, where in at least one of the heterogeneous catalysts in the first reaction zone and/or the second reaction zone is on a non-sulphided form.
