摘要： The need for silicas with large pore sizes can be met by hydrothermal treatment of a silica powder with a mineralizing agent. Pore sizes in the range 300-25,000 angstroms, and more particularly in the range up to 10,000 angstroms, are readily obtained using mineralizing agents such as hydroxide, carbonate, and fluoride at temperatures in the range 85-300.degree. C. A narrow, unimodal distribution of pores is typical.

摘要： An improved catalyst and process are disclosed for the selective disproportionation of toluene. The process uses a zeolitic catalyst which is oil-dropped in an aluminum phosphate binder and has an X-ray diffraction pattern showing characteristic intensities at specified Bragg angles. Optionally, the catalyst is selectively precoked prior to toluene disproportionation. The catalyst and process provide improved selectivity for the production of paraxylene.

摘要： Tetrahedrally charged clays have been found to be active, regenerable catalysts in detergent alkylation, both as delaminated and pillared clays. The pillared saponites and beidellites are especially favored in forming detergent range alkylates using olefins as the alkylating agent to afford products with high monoalkylation selectivity and high linearity. Catalysts can be regenerated by a benzene wash or, after severe deactivation, by a carbon burn.

摘要： A catalytic mixture of discrete solid materials and a mercaptan oxidation process for using the catalytic mixture have been developed. The catalytic mixture comprises a metal chelate dispersed on a non-basic solid support and a solid base. The process involves contacting a sour middle distillate hydrocarbon fraction which contains mercaptans with the supported metal chelate and the solid base mixture in the presence of an oxidizing agent and a polar compound. The process is unique in that both the catalyst and the base are discrete solid materials.

摘要： Novel pillared clay compositions have been synthesized. The clay contains pillars which are at least partially fluorided. These pillars are metal fluoro hydroxy cations where the metal can be Al, Zr, Si/Al, Ti or Cr. The clays which can be pillared with these pillars are the smectite clays which include hectorite and beidellite along with synthetically prepared smectite clays. These clays are prepared by pillaring the clay, followed by calcination and then treatment with a fluoride salt such as ammonium bifluoride. Finally, these fluorided pillared clays find applications in hydrocarbon conversion processes such as alkylation.

摘要： A process for forming a solid acid catalyst where all of the add functionality is covalently bonded to the organic portion of an organically-bridged polysilsesquioxane framework has been developed. The process involves polymerizing a monomer through sol-gel processing to form an organically-bridged polysilsesquioxane, reacting an acid group onto the organic portion of the organically-bridged polysilsesquioxane, and recovering the acid functionalized product. The invention also includes the product acid functionalized organically-bridged polysilsesquioxane catalyst of the process described. The catalyst is unique in that the acid functionality is incorporated within an organic-inorganic hybrid framework as opposed to being attached to pendant organic groups.

摘要： Solid solutions of magnesium oxide-aluminum oxide related to hydrotalcite and what previously has been referred to as synthetic hydrotalcites, have been prepared with a surface area in excess of 250 m.sup.2 lg, especially at low Mg/Al atom ratios. Such high surface area materials are found to be quite effective in the aldol condensation of aldehydes, and in particular in the conversion of n-butyraldehyde to 2-ethyl-2-hexenal in high yield and with good selectivity in a liquid phase reaction at temperatures under about 200.degree.
