Abstract

The invention provides a method of manufacture of a catalyst, the catalyst as such and its use in olefin oligomerisationand. The method for making an oligomerisation catalyst includes the steps of mixing alumina, silica, metal oxide, a template source; and effecting the deactivation of the Bronsted sites by masking them with metal ions, preferably either (i) during synthesis by directly adding the metal as ion in a one-pot or direct synthesis, or (ii) after intermidiate conversion to the H+-form by in turn either (ii-a) impregnating the latter with a metal salt, or (ii-b) dry-mixing a metal salt with it.

Abstract

The invention provides a method, stage and plant for removing LTFT catalyst fines and/or organometallic catalyst compounds from of LTFT wax, downstream from the LTFT reactor. The method includes at least one stage having the steps of causing a differential pressure across a filter element; causing high mechanical shearing and/or centrifugal forces along and/or away from the surface of the filter on the high pressure side of the filter to cause the particles to be continuously removed from the filter surface; and wherein the differential pressure is selected to be sufficient to force flow of the wax across the filter to cause filtration.

Abstract

This invention relates to processes for removing particles such as catalyst fines from hydrocarbon streams, such as a wax dried from a Fischer Tropsch reaction using centrifugation in combination with a treatment with an aqueous solution preferably containing an acid, or with an acid. According to an aspect of the invention, catalyst particles are removed from a wax derived from a Fischer Tropsch by pre-treating the hydrocarbon stream with an aqueous solution and forming a mixture comprising the hydrocarbon stream and 5-25% v/v organic acid solution; and introducing the mixture to a centrifuge and separating, from the mixture, a hydrocarbon stream, an aqueous solution and particles. The process may be a continuous and/or a batch process.

Abstract

This invention relates to a process for the removal of catalyst particles from a hydrocarbon stream (14) derived from the reaction of synthesis gas (12) with a particulate Fischer Tropsch catalyst in a Fischer Tropsch reactor (10). The process includes a primary separation step (16) which makes use of a filter, wherein the filter has a pore size which is 70% to 95 of the average size of the particles of the Fischer Tropsch catalyst, thereby forming a primary filtered hydrocarbon stream (18) containing fine catalyst particles. The benefit of this selection of filter pore size is that it mitigates fines build-up on the filter of the primary separator. The primary filtered hydrocarbon stream(18) is then passed to a secondary separation step in a cross-flow filtration unit (20) which removes fine catalyst particles from the primary filtered hydrocarbon stream to provide a retenate (24) containing the catalyst fines, and permeate (22) containing a hydrocarbon product.

Abstract

This invention relates to alternative diesel fuels with improved cold flow properties. The alternative fuel may be a biodiesel which typically comprises fatty acid methyl or ethyi esters; or a diesel fuel blend including diesel fuel derived from a Fischer-Tropsch (FT) reaction and possibly comprising or containing crude-derived diesel fuel and biodiesel. The cold flow properties are improved by adding a higher alcohol component which is not a naturally occurring component of the biodiesel, nor the diesel fuel.
