  • Publication number: 20150083971
    Abstract: A method and assembly for producing substantially tar free product gas from gasification of carbonaceous material. The assembly preferably includes a first stage gasifier to produce char-ash and tar laden product gas and a second stage gasifier which has a char-ash heating zone, at least one cyclone, and at least one standpipe for the purpose of allowing selective delivery of char-ash to the char-ash heating zone. A char-ash heating zone that utilizes oxidation of char-ash is preferred and this results in the heat required to convert tar, additional yield of product gas, and an oxidized, activated carbon surface to facilitate tar conversion in the riser, thereby reducing the temperature required to achieve the desired tar conversion. Alternatively, external heat is supplied to the heating zone.

    Abstract: A hydroprocessing system involves introducing heavy oil and in situ formed metal sulfide catalyst particles, or a catalyst precursor capable of forming metal sulfide catalyst particles in situ within the heavy oil, into a hydroprocessing reactor. The metal sulfide catalyst particles are formed in situ by 1) premixing a catalyst precursor with a hydrocarbon diluent to form a precursor mixture, 2) mixing the precursor mixture with heavy oil to form a conditioned feedstock, and 3) heating the conditioned feedstock to decompose the catalyst precursor and cause or allow metal from the precursor to react with sulfur in the heavy oil to form the metal sulfide catalyst particles in situ in the heavy oil. The in situ formed metal sulfide catalyst particles catalyze beneficial upgrading reactions between the heavy oil and hydrogen and eliminates or reduces formation of coke precursors and sediment.

  • Patent number: 8361405
    Abstract: A reactor vessel for subjecting a first gas and a second gas to a chemical reaction to produce a third gas is provided. The reactor vessel includes a catalyst bed, an inlet for receiving the first gas and the second gas, and a first outlet for discharging the third gas. The first outlet includes a selective microporous conduit to separate the third gas from products of incomplete reaction or unreacted first gas and unreacted second gas. A second outlet for discharging one or more of the following: unseparated third gas is also included in this invention. The products of incomplete reaction, unreacted first gas, or unreacted second gas are removed from the system. At least one helical tube is disposed within the reactor vessel and in direct contact with the catalyst bed. The helical tube has an inlet end communicating with a hot gas source, and an outlet end exhausting cooled gas. Indirect heat exchange between the helical tube and the first and second gas, promoted by the catalyst, generates the third gas.

  • Publication number: 20120294784
    Abstract: Embodiments of methods and apparatuses for producing styrene are provided. The method comprises the steps of introducing ethylbenzene to a first dehydrogenation reactor containing a first high activity dehydrogenation catalyst at a first predetermined inlet temperature to form a first intermediate effluent stream that comprises styrene, ethylbenzene, and hydrogen. Oxygen is added to the first intermediate effluent stream to form a first oxygenated intermediate effluent stream. The first oxygenated intermediate effluent stream is introduced to a first oxidation-reheat dehydrogenation reactor at a second predetermined inlet temperature of about 530° C. or less to form styrene. The first oxidation-reheat dehydrogenation reactor contains a first oxidation catalyst and a second high activity dehydrogenation catalyst.
