Process for producing hydrocarbons

Acid Degumming of Carinata Oil

[0253]Acid degumming of Brassica carinata oil is carried out by treating 100 g of the oil with 1 wt % phosphoric acid (85 wt-%) at 80° C. temperature for 30 min, whereby gums are separated / precipitated and then removed by centrifuging. The phosphorus value of the degummed oil is lower than 15 ppm.

Hydrolysis of Degummed Carinata Oil

[0254]The degummed oil obtained in example 1 is directed to hydrolysis, where the degummed oil is treated with 50 wt % of water under a pressure of 42 bars and a temperature of 250° C. in a tubular reactor, for 1.5 hours, to obtain an aqueous stream comprising glycerol and a stream comprising fatty acids (=pretreated feedstock).

Hydroprocessing Pretreated Feedstock

[0255]The pretreated feedstock obtained in example 2 is directed to one-step hydroprocessing, where the pretreated feedstock is hydroprocessed at 350-400° C. temperature, under 90 bar pressure, in the presence of a catalyst comprising NiW and NiMo, with hydrogen to obtain an effluent consisting of liquid phase and gas phase. Gas phase and water are separated and a phase comprising liquid hydrocarbons is obtained. Heavy hydrocarbons having carbon number of at least C20 (those boiling in the range from and above 320° C.) are separated by distillation (=hydroprocessed feedstock) and this hydroprocessed feedstock is directed to fluid catalytic cracking.

Fluid Catalytic Cracking of Hydroprocessed Feedstock

[0256]Vacuum gas oil (90 vol-%) originating from crude oil is combined with the hydroprocessed feedstock (10 vol-%) obtained in example 3 to obtain a mixture, which is heated to a temperature of 370° C. and directed to fluid catalytic cracking re
