Abstract: The present invention relates to a baffle arrangement that improves separation of gaseous hydrocarbon reaction products from catalyst within the reactor vessel of a fluidized catalytic cracker unit. The catalytic reactor vessel includes an outer generally cylindrical shell having a stripping zone arranged at the lower end of the vessel. An inlet riser conduit forming a primary reaction zone extends generally within the shell from the lower end of the vessel to a location near the top of the vessel. A shroud surrounds the upper end of the riser conduit and forms an annular outlet for downwardly discharging a mixture of hydrocarbon and catalyst. According to the present invention, an annular catalyst disengaging riser baffle for deflecting the mixture from the outlet toward the wall of the vessel is arranged on the outside of the riser conduit below the annular outlet and above the stripping zone.
Abstract: A process is provided for conducting organic compound conversion over a catalyst comprising a crystalline zeolite which has been treated by reaction with a compound having a complex fluoroanion.
Abstract: Conversion of the synthetic gas mixtures: carbon monoxide - hydrogen or carbondioxide - hydrogen is carried out in the presence of a catalyst constituted by the association of at least two transition metal elements with an acitve mordenite selected from among de-aluminized acid mordenites. The metal elements can be copper, zinc and chromium. The transition metal elements - active mordenite association can be employed in separate catalytic beds, the first bed being metallic in nature and the second zeolitic in nature. The process is applicable to the manufacture of organic products such as saturated and unsaturated hydrocarbons, particularly light olefines.

Abstract: A process is provided for conducting organic compound conversion over a catalyst composition comprising a supported crystalline zeolite having a high initial silica-to-alumina mole ratio, said supported zeolite being prepared by compositing said crystalline zeolite with alumina, reacting the composite with a particular hydrogen fluoride solution in a specified way, drying the hydrogen fluoride reacted composite, treating the dried composite by hydrolysis, ammonolysis and/or by contact with an ammonium salt solution, and calcining the resulting material.
Abstract: The high boiling fraction of Fischer-Tropsch synthesis is upgraded by contact with a catalyst comprising a high-silica, large pore zeolite and a hydrogenation component. The products are a distillate fraction characterized by low sulfur and nitrogen content, high isoparaffin content and low pour point and a lube fraction characterized by its high viscosity index and low pour point.
