    摘要: A process for the dehydrogenation of paraffins is presented. The process utilizes a rapid recycling of dehydrogenation catalyst between the dehydrogenation reactor and the catalyst regeneration unit. The process comprises preheating a combined hydrogen and paraffin hydrocarbon feedstream and passing the combined stream to a dehydrogenation reactor. The hydrocarbon feedstream and the catalyst pass through the reactor at a rate to limit the average residence time of the catalyst in the reactor. The catalyst is cycled to a regeneration unit, and passed through the regeneration unit to limit the average residence time of the catalyst in the regeneration unit.

    摘要: Systems and methods of improving synthesis gas quality in a fluid catalytic cracking unit are disclosed. In one example, a method comprises reacting a first stage regeneration gas comprising oxygen with spent catalyst from a reactor in a first stage of a regenerator to consume the oxygen in the first stage regeneration gas. This reaction produces a synthesis gas output and partially regenerated catalyst. The method further comprises reacting a second stage regeneration gas comprising oxygen with the partially regenerated catalyst in a second stage of the regenerator to regenerate the partially regenerated catalyst. This reaction produces the first stage regeneration gas for reaction with the spent catalyst in the first stage of the regenerator. Through the first and second stage reactions, the spent catalyst is regenerated and the synthesis gas quality is improved.

    摘要: Systems and methods of reducing refinery carbon dioxide emissions by improving the overall synthesis gas yield in a fluid catalytic cracking unit having a reactor and a regenerator are discussed. In one example, a method comprises introducing spent catalyst and a feed gas comprising oxygen to the regenerator at gasification conditions. The method further comprises heating the spent catalyst to burn coke therefrom to produce a synthesis gas. The method further comprises combining the synthesis gas with a dry gas comprising hydrogen, creating the overall synthesis gas and thereby increasing the yield of the overall synthesis gas produced in the FCC unit.
