A process and catalyst for the hydro-oxidation of an olefin having three or more carbon atoms, such as propylene, to form an olefin oxide, such as propylene oxide. The process involves contacting the olefin with oxygen in the presence of hydrogen and a hydro-oxidation catalyst under reaction conditions; the catalyst comprising gold nanoparticles deposited on a nanoporous titanium-containing support, prepared by depositing a gold-ligand cluster complex onto the support to form a catalyst precursor, and then heating and/or chemically treating the catalyst precursor to form the hydro-oxidation catalyst composition. The hydro-oxidation catalyst exhibits stabilized catalyst activity, enhanced lifetime, and improved hydrogen efficiency.

Nano-scale DMC catalyst complexes are highly active alkylene oxide polymerization catalysts. Thy show a greatly improved ability to catalyze the formation of EO-capping onto secondary hydroxyl-terminated polyethers. The catalysts can be prepared by precipitation in the dispersed adequous phase of a water-in-oil emulsion.

A process for catalytic cracking of a hydrocarbon feedstock feeds to produce an enhanced yield butylenes and isobutane comprises contacting the feedstock with a catalyst composition comprising MCM-68. The MCM-68 may be used as the primary cracking catalyst or may be used as an additive component in conjunction with a conventional cracking catalyst, such as a large pore molecular sieve having a pore size greater than 7 Angstrom.

A new synthetic porous crystalline material, designated EMM-1, is disclosed having, in its calcined form, the X-ray diffraction pattern of Table 2 above. Also disclosed are methods of making EMM-1 in the presence of HF using various organic nitrogen compounds as directing agents. Aluminum-containing EMM-1 can be produced either by inclusion of Al in the synthesis, or by incorporation of B or Ga in the synthesis, followed by post treatment with aluminum nitrate or other sources of Al. EMM-1 is useful as an acid catalyst and as an adsorbent.
