  • Patent number: 8344199
    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.

  • Patent number: 7776208
    Abstract: This disclosure discusses integrating syngas streams with refinery hydrotreators, synthetic hydrocarbon gas to liquid (GTL) processes, and power generation units (such as combined cycle units) to efficiently use hydrogen contained in the syngas produced from heavy hydrocarbons (pet coke, residues, oil, etc.). Membrane separation and pressure swing adsorption is used to separate components of syngas and feed them to refineries, GTL units, and power/steam generation units. Hydrogen-rich refinery purge is used to raise the H2/CO ratio of syngas. A hydrogen-enriched syngas is produced with an H2/CO ratio favorable for the production on synthetic hydrocarbons (greater than about 1.5 to about 2.0 or higher). Pure hydrogen is also produced in a PSA unit, to further raise the H2/CO ratio of the syngas and provide hydrogen feed for refinery hydrotreators and synthetic hydrocarbon units (such as methanol units).

  • Patent number: 7763763
    Abstract: The present invention provides a process for the production of olefins wherein a synthetic naphtha is passed to a steam cracker. The synthetic naphtha is derived from the fractionation of a Fischer-Tropsch product stream. The Fischer-Tropsch product stream may be separated into a lighter fraction and a heavy fraction and the heavy fraction may be hydrotreated prior to fractionation. Optionally the synthetic naphtha may be hydrogenated to produce a saturated synthetic naphtha which can then be subsequently passed to the steam cracker.
