20140296592 | PROCESS FOR THE FLUID CATALYTIC CRACKING OF OXYGENATED HYDROCARBON COMPOUNDS FROM BIOLOGICAL ORIGIN - A process for the fluid catalytic cracking of oxygenated hydrocarbon compounds from biological origin. The process comprises (a) contacting a feed comprising the oxygenated hydrocarbon compounds with a fluid catalytic cracking catalyst at elevated temperature to produce a cracked products stream, the feed comprising an amount of sulphur; (b) separating catalyst from the cracked products stream; (c) separating a light fraction from the cracked products stream; and (d) removing hydrogen sulphide from the light fraction by means of an amine treating process. The fluid catalytic cracking process involves the presence or use of water and/or steam and comprises a working-up process of the cracked products stream. In the working-up process, one or more chemical additives for reducing or hindering the formation of foam in amine liquids selected from defoamers and demulsifiers are added to the amine solvent in one or more amine treaters. | 10-02-2014 |
20140296593 | PROCESS FOR THE FLUID CATALYTIC CRACKING OF OXYGENATED HYDROCARBON COMPOUNDS FROM BIOLOGICAL ORIGIN - A process for the fluid catalytic cracking of oxygenated hydrocarbon compounds from biological origin. The process comprises contacting a feed comprising the oxygenated hydrocarbon compounds from biological origin and an amount of sulphur with a fluid cracking catalyst at a temperature of equal to or more than 400° C. to produce a products stream. The process further comprises separating fluid cracking catalyst from the products stream and separating a light fraction from the products stream; and removing hydrogen sulphide from the light fraction by means of an amine treating process. Activated carbon is used to treat at least part of an amine solution used in the amine treating process or to treat at least part of the feed to the amine treating process. | 10-02-2014 |
