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.

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.

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.

Abstract: A carrying case for transporting fishing equipment from one location to another. The carrying case generally comprises an external container and an insert insertedly situated within the external container. The external container is substantially cylindrical in shape with an open top and a closed bottom. The insert includes a lid, a base, and a support connecting the lid to the base. A plurality of cutouts are provided in the lid of the insert for receiving the shafts of a plurality of fishing rods. A plurality of seats are provided along the base of the insert for receiving the handles of the fishing rods. A storage space is also provided between the base of the insert and the base of the external container for storing other fishing equipment including fishing tackle. A series of ribs are provided along the walls of the external container near the base of the external container for mating with the base of the insert.

Abstract: An optical dielectric waveguide comprises a track made of a low loss material disposed in the form of a helix. Information in the form of a modulated light can be transmitted along said track. Preferably said substance is silica.
