Abstract: A process for preparing hydrocarbons from an oxygenated hydrocarbon feedstock, such as animal fat, having a high nitrogen impurity is described. Hydrotreatment of the oxygenated feedstock occurs in a first hydrotreating bed arranged downstream of a polishing bed. A gaseous phase is removed and the liquid hydrotreated phase is fed to the polishing bed arranged upstream of the first hydrotreating bed together with fresh hydrogen. The process effectively removes nitrogen impurities from the resultant hydrocarbon product causing an improved cloud point after isomerisation, and the arrangement makes efficient use of fresh hydrogen for polishing, providing a polished hydrocarbon product rich in dissolved hydrogen. Part of the product can be used as hydrocarbon diluent in the downstream hydrotreating bed, and/or withdrawn between the polishing and hydrotreating bed and isomerised in an isomerisation reactor.

Abstract: A system for catalytic cracking of hydrocarbon oils has a catalytic cracking reactor, a catalyst separation device, an optional reaction product separator, and a regenerator. A catalytic cracking reactor has a dilute-phase transport fluidized bed and a fast fluidized bed connected in series for reaction. In the fast fluidized bed, the axial solid fraction ε of the catalyst is controlled within the range of about 0.1 to about 0.2. When used for catalytic cracking of hydrocarbon oil feedstocks, particularly heavy feedstock oils, the process and system show lower yields of dry gas and coke, and good product distribution.

Abstract: A process for preparing hydrocarbons from an oxygenated hydrocarbon feedstock, such as animal fat, having a high nitrogen impurity is described. The process involves hydrotreatment of the oxygenated feedstock in a first hydrotreating reactor and a further hydrotreatment in a second hydrotreating reactor, where between the two reactors, the gaseous phase is removed. The specific process setup effectively removes nitrogen impurities from the resultant hydrocarbon product causing an improved cloud point after isomerisation.

Abstract: Separation methods for producing an extract and a raffinate from a solvent extraction feed material, wherein the feed material is derived from a process for recovering bitumen from oil sands. The methods may include producing an intra-stage recycle component from an overflow zone of a solvent extraction stage and recycling the intra-stage recycle component to the solvent extraction stage, and/or the methods may include providing an underflow component withdrawal rate for a solvent extraction stage other than a final solvent extraction stage which is greater than an underflow component withdrawal rate for the final solvent extraction stage.

Abstract: A process for the hydroprocessing of a gas oil (GO) hydrocarbon feed to provide high yield of a diesel fraction. The process comprises a liquid-full hydrotreating reaction zone followed by a liquid-full hydrocracking reaction zone. A refining zone may be integrated with the hydrocracking reaction zone. Ammonia and other gases formed during the hydrotreatment are removed in a separation step prior to hydrocracking.
