International Classification:

C07C 406

US Classification:

585653, 585650, 585651, 585407, 585418

Abstract:

A catalyst and an improved process for producing olefins by catalytic naphtha cracking are described. The process provides relatively higher yields over a commercially important range of naphtha conversion, while providing about the same or lower yields of aromatics and methane over the range. In the process, a hydrocarbon naphtha feedstock including a hydrocarbon having about three to about twenty carbon atoms per molecule is passed into a reactor containing a pentasil zeolite catalyst. The catalyst includes about 0. 1 to about 10 weight percent phosphorus and about 0. 1 to about 10 weight percent of a promoter metal selected from the group consisting of gallium, germanium, tin and mixtures thereof. The hydrocarbon may be passed into the reactor together with a diluent selected from the group consisting of steam, nitrogen, methane, and ethane and mixtures thereof. Alternatively, the hydrocarbon may be passed into the reactor together with additional propane.

US Classification:

549523, 549533, 549536

Abstract:

The invention is a process for epoxidizing an olefin with hydrogen and oxygen in the presence of a noble metal-containing titanium or vanadium zeolite and a modifier selected from the group consisting of carbon monoxide, methylacetylene, and propadiene. The process results in significantly reduced alkane by-product formed by the hydrogenation of olefin compared to processes that do not use the carbon monoxide, methylacetylene, and/or propadiene modifier.

Assignee:

Lyondell Chemical Technology, L.P. - Greenville DE

International Classification:

B01J 20/34

US Classification:

502 38

Abstract:

Used noble metal-containing titanium zeolite catalysts, that have been employed in the liquid-phase epoxidation of olefins with hydrogen and oxygen in the presence of a buffer, are regenerated by heating the used catalyst at a temperature of at least 250 C. in the presence of a oxygen-containing gas stream, followed by reduction at a temperature of at least 20 C. in the presence of a hydrogen-containing gas stream to form a reactivated catalyst.

Abstract:

A process is disclosed for the epoxidation of an olefin with hydrogen and oxygen in the presence of an oxidation catalyst comprising a transition metal zeolite, and a noble metal catalyst comprising a noble metal and an ion-exchange resin. The process is highly productive and selective in making epoxides. A noble metal catalyst comprising a cation-exchanged resin further improves the productivity and/or the selectivity of the process.
