Embodiment Construction

[0017] The present invention relates to a process for the fluid catalytic cracking of oxygenated hydrocarbon compounds of biological origin. Such fluid catalytic cracking (FCC) processes may suitably be carried out in a fluid catalytic cracking (FCC) unit comprising one or more fluid catalytic cracking (FCC) reactors.

[0018] Modern FCC plants can operate continuous processes that can operate 24 hours a day for periods of two to four years. A detailed description of FCC technology can be found, for example, in "Fluid Catalytic Cracking technology and operations", by Joseph W. Wilson, published by PennWell Publishing Company (1997), and in "Fluid Catalytic Cracking; Design, Operation, and Troubleshooting of FCC Facilities", By Reza Sadeghbeigi, published by Gulf Publishing Company, Houston Texas (1995).

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.

Description

technical field [0001] The present invention relates to a process for the fluid catalytic cracking of oxygenated hydrocarbon compounds of biological origin. Background technique [0002] Fluid catalytic cracking (FCC) is an important conversion process in current refineries. It can be used to convert high boiling hydrocarbon fractions of crude oil origin into more valuable products such as gasoline components (naphtha), fuel oils and (olefinic) gases (ethylene, propylene, butenes, LPG). [0003] With the reduction of crude oil supply, the application of renewable energy is becoming more and more important for the production of liquid fuels. These fuels from renewable sources are often referred to as biofuels. Such renewable energy sources can also be used as feedstock for fluid catalytic cracking processes. [0004] For example, Tian Hua et al. published in the Chinese Journal of Chemical Engineering, vol.16(3), pp. 394-400 (2008) titled "Alternative Processing Technology...
