An oligomerization process in which hydrocarbon feedstocks are contacted with a hydrotreating catalyst in the absence of hydrogen and in the liquid phase. The catalyst is a heterogeneous catalyst selected from supported reduced metals, metals oxides, metal sulfides and combinations thereof. Preferred catalysts include mixed nickel and molybdenum oxides or mixed cobalt and molybdenum oxides. The process also oligomerizes sulfur compounds so that sulfur containing feedstocks can be treated without deactivating the catalysts.

Conversion of unsaturated chemicals to oligomers

The patent application discloses an integrated process for reformate upgrading. Such a process enables production of a high value product slate, by incorporating the step of reforming along with reaction/diffusion with a zeolite.

Reformate upgrading using zeolite catalyst

A process for the synthesis of alkylene carbonates, such as ethylene carbonate, by reacting alkylene oxides with carbon dioxide in the presence of a porous solid support catalyst containing an alkali or alkaline earth metal component.

Process for producing alkylene carbonates

This invention relates to a new synthetic porous crystalline material, designated MCM-68, a method and novel polycyclic organic cation for its preparation and its use in catalytic conversion of organic compounds. The new crystalline material exhibits a distinctive X-ray diffraction pattern and has a unique crystal structure which contains at least one channel system, in which each channel is defined by a 12-membered ring of tetrahedrally coordinated atoms, and at least two further, independent channel systems, in each of which each channel is defined by a 10-membered ring of tetrahedrally coordinated atoms, wherein the number of unique 10-membered ring channels is twice the number of 12-membered ring channels.

Synthetic porous crystalline MCM-68, its synthesis and use

A process is described for isomerizing a feed which contains ethylbenzene and xylene, which process comprises the steps of:

Xylene isomerization

A method of producing ethyl acetate by reacting acetic acid with ethylene in the presence of a solid acidic catalyst comprising a zeolite selected from the group consisting of MCM-22, MCM-49, MCM-56, ZSM-5 and zeolite-Beta.
