  • Patent number: 10844287
    Abstract: The present invention provides a method for preparing gasoline and aromatics by using Fischer-Tropsch synthesis exhaust. The method includes conducting an olefin conversion reaction on Fischer-Tropsch synthesis exhaust under the action of a first molecular sieve catalyst. A first refrigeration or cooling is conducted on an obtained product to obtain ultralow sulfur-containing gasoline and first-stage reaction gas. An alkaline aromatization reaction is conducted on the first-stage reaction gas under the action of a second molecular sieve catalyst. A second refrigeration or cooling is conducted on an obtained product to obtain aromatics. After the olefin conversion reaction, a gasoline component is separated and residual alkanes enter a second-stage fluidized bed reactor for the alkane aromatization reaction to produce aromatics.

  • Patent number: 10414701
    Abstract: Systems and methods are provided for forming alkylate from an isoparaffin-containing feed. Olefins for the alkylation reaction can be generated from a portion of the isoparaffin-containing feed. This can be achieved, for example, by using selective oxidation to convert a portion of isoparaffins into alcohol, such as conversion of isobutane to t-butyl alcohol. The alcohol can then be converted to an alkene, such as conversion of t-butyl alcohol to isobutene, in the alkylation reaction environment in the presence of a solid acid catalyst. The solid acid catalyst can then facilitate alkylation of isoparaffin using the in-situ formed alkenes. A catalyst having an MWW framework is an example of a suitable solid acid catalyst.

  • Publication number: 20150099913
    Abstract: A methanol conversion process comprises contacting a feedstream comprising methanol, optionally with dimethyl ether or other oxygenates with a catalyst comprising a physical mixture of a molecular sieve, preferably an intermediate or small pore size zeolite such as an MFI zeolite, with a basic metal oxide to provide extended catalyst cycle life by reducing the incidence of coke formation. The process may be applied to the methanol-to-gasoline (MTG), methanol to distillate (MOD), methanol-to-olefins (MTO), methanol-to-chemicals (MTC) and combination processes such as the MTO/OCP Process.

  • Publication number: 20150099915
    Abstract: A process for producing short-chain olefins by conversion of oxygenates in a multi-stage fixed-bed reactor, in which the individual stages for reaction zones are covered with beds of a granular, form-selective zeolite catalyst and the feed mixture containing oxygenates is added distributed over the reaction stages. An increase of the availability of the fixed-bed reactor for the olefin production with the same or an increased yield of short-chain olefins is achieved in that one or more reaction zones are charged with a distinctly reduced mass flow of the feed mixture containing oxygenates, wherein the reduced mass flow fraction is distributed over other reaction zones.

  • Patent number: 9000246
    Abstract: Methods are provided for refining natural oil feedstocks and producing dibasic esters and/or dibasic acids. The methods comprise reacting a terminal olefin with an internal olefin in the presence of a metathesis catalyst to form a dibasic ester and/or dibasic acid. In certain embodiments, the olefin esters are formed by reacting the feedstock in the presence of a metathesis catalyst under conditions sufficient to form a metathesized product comprising olefins and esters, separating the olefins from the esters in the metathesized product, and transesterifying the esters in the presence of an alcohol to form a transesterified product having olefin esters.

  • Patent number: 8993818
    Abstract: Technologies to convert biomass to liquid hydrocarbon fuels are currently being developed to decrease our carbon footprint and increase use of renewable fuels. Since sugars/sugar derivatives from biomass have high oxygen content and low hydrogen content, coke becomes an issue during zeolite upgrading to liquid hydrocarbon fuels. A self-sustainable process was designed to reduce the coke by co-feeding sugars/sugar derivatives with the paraffin products from hydrogenation of sugars/sugar derivatives. Paraffins without complete conversion result in products with less aromatics and relatively low density compared with the products directly from zeolite upgrading. Thus, the process is more economically favorable.

These are each passed to one catalyst bed in such a manner that the weight ratio of diluting agent to raw material feed is essentially the same at the entrance of all catalyst beds and does not exceed 4:1. The claimed process is preferably conducted at low temperatures and allows the utilization of existing units due to the low recycle ratio.
