The present invention relates to a process for the manufacture of furan compounds by the direct oxidation of conjugated diolefins with air or oxygen in the liquid phase in the presence of a transition metal catalyst system.

Process for the manufacture of furan compounds

A method for preparing a high-surface area catalyst consisting of high-surface area support material coated on an inert core. The inert core is partially wetted with a wetting agent and a powdered, high-surface area coating is then applied to the core. The coated core can be dried and calcined, and additional catalytic elements can be added by impregnating the core with solutions containing such elements.

High-surface area coated support for catalysts and process for their

Catalysts consisting of a base support having a strongly adherent outer coating of an active catalytic material have been found to give superior results in known hydrogen processing reactions wherein sulfur, nitrogen and the metal content of a hydrogen feedstock are reduced.

Hydrogen processing of hydrocarbon feeds using coated catalysts

Separation of certain water soluble organic monomers such as acrylic acid from an aqueous solution can be accomplished by extraction with carbon dioxide, crystallizing the extract to remove carbon dioxide hydrate, and flashing off the remaining carbon dioxide solvent from the extract.

Dehydration of water soluble monomers with liquid carbon dioxide

The present invention relates to an improved method of catalyst presulfiding, wherein the catalyst is treated with elemental sulfur. The use of elemental sulfur as a catalyst presulfiding agent is a means of rapidly and reproducibly attaining a highly active catalyst.

Hydrotreating process utilizing elemental sulfur for presulfiding the

Improved amphora aggregates having a substantially spherical shape, a void center and two cavities 180.degree. apart in the external surface communicating to the void center are useful in diffusion-limited reactions and/or reactions in which heat transfer is critical. Especially preferred is use of the amphora aggregates in the hydrotreating of light hydrocarbon fractions, catalytic reforming, and fixed-bed alkylation processes.

Amphora aggregates and the process for their preparation

Process for preparing improved amphora aggregates

Catalysts having a substantially spherical shape, a void center and a hole in the external surface communicating to the void center, have been found to give superior results in known hydrotreating reactions where sulfur, nitrogen and/or oxygen is removed from a hydrocarbon feed stock.
