  • Patent number: 8021632
    Abstract: The invention relates to a plant for carrying out chemical reactions, having a reactor (1), the reaction space of which contains hydrogen peroxide (H2O2) and titanium silicalite (TS-1). The object of the invention is to improve such a plant such that continuous separation and recycling of the active catalyst to the reaction space is possible with a long filter service life. This is achieved in that the reaction space contains a solid silicon source, in that the plant comprises a water takeoff line (3) which is set up for drawing off water in addition to components which are dissolved and/or dispersed therein from the reaction space, in that the water takeoff line (3) leads to a filter (4) which separates off the components which are dissolved and/or dispersed in the water, and in that the plant has a return line (5) which is set up for recirculating to the reaction space components which are separated off by means of the filter (4).

  • Patent number: 7967954
    Abstract: A process for the conversion of hydrocarbons that are solid or have a high boiling temperature and may be laden with metals, sulfur or sediments, into liquids (gasolines, gas oil, fuels) with the help of a jet of gas properly superheated between 600 and 800° C. The process comprises preheating a feed 5 in a heater 8 to a temperature below the selected temperature of a reactor 10. This feed is injected by injectors 4 into the empty reactor 10 (i.e., without catalyst.) The feed is treated with a jet of gas or superheated steam from superheater 2 to activate the feed. The activated products in the feed are allowed to stabilize at the selected temperature and at a selected pressure in the reactor and are then run through a series of extractors 13 to separate heavy and light hydrocarbons and to demetallize the feed. Useful products appearing in the form of water/hydrocarbon emulsions are generally demulsified in emulsion breaker 16 to form water laden with different impurities.

    Abstract: The invention relates to a method and a system for operating a Fischer-Tropsch synthesis, wherein a feed gas comprising CO and H2 from coal gasification (1) is desulfurized and subsequently fed into a Fischer-Tropsch synthesis as an input gas, wherein hydrocarbons are formed from carbonic oxides and hydrogen by catalytic reactions. The hydrocarbons are separated as liquid products (4), and a gas flow comprising CO and CO2 exiting the Fischer-Tropsch synthesis unit (3) is compressed and fed into a conversion stage, wherein CO and steam are transformed into H2 and CO2. In the method according to the invention, the gas exiting the conversion stage is fed back into the Fischer-Tropsch synthesis unit as a gas rich in H2, together with the desulfurized input gas, after the gas is prepared in that CO2 and/or further components other than H2 are removed.

  • Publication number: 20110031162
    Abstract: A method and apparatus for producing a treated hydrocarbon containing stream for use as a feed to a hydrogen plant having a steam methane reformer in which an untreated hydrocarbon containing stream is introduced into two reaction stages connected in series to hydrogenate olefins and to convert organic sulfur species to hydrogen sulfide. The second of the two stages can also be operated in a pre-reforming mode to generate additional hydrogen through introduction of the oxygen and steam into such stage. A sulfur tolerant catalyst is used in both stages to promote hydrogenation and oxidation reactions. Sulfur is removed between stages by adsorption of the hydrogen sulfide to prevent deactivation of the catalyst in the second of the stages that would otherwise occur during operation of the second reaction stage in a pre-reforming mode of operation.
