  • Publication number: 20220298426
    Abstract: A reactor and a process for fluid catalytic cracking (FCC) a hydrocarbon feed in the riser-reactor, the process including injecting the hydrocarbon feed into an evaporation zone of the riser-reactor, injecting a first catalyst into the evaporation zone, wherein the first catalyst mixes with the hydrocarbon feed to generate a hydrocarbons stream in the evaporation zone, and wherein the temperature in the evaporation zone is less than 625° C., and passing the hydrocarbons stream from the evaporation zone into a cracking zone of the riser-reactor to generate a cracked product in the cracking zone.

  • Publication number: 20140296593
    Abstract: 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.

  • Publication number: 20140296592
    Abstract: 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.

  • Publication number: 20140296594
    Abstract: 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 from biological origin with a fluid cracking catalyst at a temperature of equal to or more than 400° C. to produce a products stream; (b) separating fluid cracking catalyst from the products stream and separating a fraction comprising one or more C1-C4 hydrocarbon compounds from the products stream; and (c) processing the fraction comprising one or more C1-C4 hydrocarbon compounds in a work-up process, which comprises one or more oil/water separation steps. One or more de-emulsifiers are added to one or more oil/water separation steps.
