    摘要: Synthesis gas is produced by the reaction of light hydrocarbons, primarily methane, in a fluid bed reaction zone of attrition resistant nickel on alpha-alumina catalyst, with steam and oxygen and the conversion level is preserved by limiting the loss of nickel from the reaction and thereby limiting the back reaction of the synthesis gas to form methane in the presence of entrained catalyst in a cooling zone.

    摘要: A catalytic cracking process and apparatus wherein particles of cracking catalyst circulate continuously between a reaction zone and a regeneration zone and hot regenerated catalyst from the regeneration zone contacts hydrocarbon feed in the reaction zone to produce cracked hydrocarbon products and spent catalyst. The spent catalyst is recovered and subjected to stripping in a stripping zone to remove strippable material therefrom. The stripped spent catalyst is circulated to the regeneration zone for oxidative exothermic regeneration. Some hot regenerated catalyst is passed directly from the regenerator to the stripping zone via a conduit provided for this purpose. Another hydrocarbon stream is passed into contact with the hot regenerated catalyst in this conduit. The said other hydrocarbon stream is converted to products of enhanced value (e.g., olefins) during contact with catalyst in the conduit, and the said products are recovered. The heat for the conversion is abstracted from the catalyst particles passing via the pipe to the stripping zone. The hot catalyst particles entering the stripping zone from the pipe increase the temperature in the stripping zone, thereby improving the stripping in the stripping zone.

    摘要: A fluid catalytic cracking process for producing relatively low emissions fuels. The feedstock is exceptionally low in nitrogen and aromatics and relatively high in hydrogen. The catalyst is an amorphous silica-alumina or a zeolitic material having a relatively small unit cell size. The feedstock can be characterized as having less than about 50 wppm nitrogen; greater than about 13 wt. % hydrogen; less than about 7.5 wt. % 2+ring aromatic cores; and not more than about 15 wt. % aromatic cores overall.

    摘要: A process for converting hydrocarbons to aromatic compounds comprising contacting a paraffinic or olefinic hydrocarbon feedstream, without added hydrogen, with a catalyst comprising from about 0.05 to about 5% of palladium metal and from about 0.1 up to 2% chromium oxides composited with a high surface area support. A preferred process is one for aromatization of such feeds by contact with a catalyst comprised of from about 0.05 to about 5% of palladium metal, from about 0.1 to less than 2% chromium oxide and up to about 4.5% by weight of an alkali metal oxide incorporated therewith to increase the aromatization activity of the catalyst. Catalysts used in accordance with the present invention comprise compositions which include from about 0.05 to about 5% palladium, from about 0.01 to less than 2% chromium oxides and up to about 4.5% of an alkali metal oxide.
