US Classification:

549512, 549534, 549536, 502347

Abstract:

A high activity and high selectivity silver catalyst comprising silver and, optionally, one or more promoters supported on a suitable support material having the form of a shaped agglomerate. The structure of the shaped agglomerate is that of a hollow cylinder having a relatively small inside (bore) diameter. The catalyst is made by providing the shaped material of a particular geometry and incorporating the catalytic components therein. The catalyst is useful in the epoxidation of ethylene.

US Classification:

702 19, 702 20, 703 11, 703 12, 502347

Abstract:

A process for selecting shaped particles for use in a tube which is capable of being packed with shaped particles to form a packed bed in the tube. A desired value of one or more properties of the packed bed is defined. The dimensions of the shaped particles are calculated such that a packed bed in the tube of the shaped particles having the calculated dimensions meets or substantially meets the desired value(s), and shaped particles are selected in accordance with the calculated dimensions. The properties of the packed bed may be the volume fraction which is occupied by shaped particles, the packing density, and the resistivity for a gas flowing through the packed bed.

US Classification:

549536, 549534, 568867

Abstract:

A process for the production of an olefin oxide, which process comprises reacting a feed comprising an olefin and oxygen in a reactor tube in the presence of a silver-containing catalyst, wherein the presence of water in the catalyst bed is controlled such that the ratio of the partial pressure of water (PPHO) divided by the vapor pressure of water (VPHO) is less than 0. 006, preferably less than 0. 004.

US Classification:

702019000

Abstract:

A method of identifying a relationship between a set of one or more candidate biomolecules and a set of one or more reference biomolecules, the method including inputting to a computer a query set describing the one or more candidate biomolecules; comparing the query set with a target database describing the one or more reference biomolecules wherein the one or more reference biomolecules grouped into one or more buckets and wherein the one or more reference biomolecules of each bucket share a common property; counting a number of matches between each query set and each buckets of the target database; and statistically analyzing the number of matches to each bucket wherein the presence of a statistically significant match identifies a relationship between a the query set and a bucket of the target database.
