Title: Imbedded catalyst for removal of sulphur compounds and nitrogen oxides from fluid streams
Inventor: GUNNING HARRY
IPC: B01J27/02
Filed: 1991-07-08
Abstract: The invention comprises an improved form of regeneratable catalyst that is capable of providing reactive oxygen to partially oxidize sulphur-containing compounds to produce sulphur. Such catalyst is useful for a method of removing sulphur compounds including both sulphur oxides and hydrogen sulphide from a fluid stream and decomposing such compounds to produce sulphur. The improved catalyst is formed by depositing alkali metal sulfide and sulfide(s) or selenide(s) of metal(s) showing polyvalent and/or amphoteric character, e.g. Zn, etc. within the matrix or body of a microporous type support, preferably alumina, to produce an imbedded catalyst. Its activity is sustained by exposure to a source of oxygen, such as air, oxygen sulphur dioxide or nitrogen peroxide and the like. A catalyst so formed may be used to absorb sulphur dioxide from flue gas and converted it to sulphur, while higher oxides of nitrogen and carbon dioxide are being absorbed for subsequent recovery.

Title: New batch blender or new continuous blender design based on a new invention a mixing tool
Inventor: CAMPBELL CRAIG C
IPC: B01F15/00
Filed: 1991-07-09
Abstract: p. 2 ABSTRACT           A linear mixing tool, triangular in cross section, a wedge, is des-cribed which exhibits outstanding performance and extreme versitility. There are many significant advantages.  Use may be stationary or for attachment to a rotating shaft inside a blender.  The tool transports, blends, and cools (or heats) material simultaneously.  Rotating and stationary tools may be used in combination.  The leading edge of the wedge, the point of the V, moves through the matrix like a plow (the apex of two intersecting planes) resulting in vector forces with rapid lateral back-and-forth movement  of particles ( in the usual case of multiple tools).         Rather than being married  to a fixed blender design character, with the use of this tool, the blender adaption becomes quite variable.  By change of orientation, right or left, the degree of output (trans port), forward or backward, may be controlled.  Zones of control within the blender are possible: forward movement, holding, or re-verse flow may be controled.  Thus, the degree of filling within se-lected zones is possible.  Tempary variation of control during ex-periments is easily accomplished.     ABSTRACT (continued) Blender design based on the new invention, the triangular tool, offers a great deal of promise for both research and pro-duction. The blender using the tool, design of this embodiment has application to a wide variation of matricies. Blender function can be adapted to a wide variation retention time, quality of mixing, and output - for controled period testing or for per-mnnent set-up for production.

Patent CA-2054816-A1 (CA)
Title: Aromatic alkylation process
Inventor: SY ANGEL
IPC: B01D3/00
Filed: 1991-11-01
Abstract: A process for the catalytic distillation production of alkylated aromatic compounds is provided wherein the vapor pressure of the olefin may be increased while maintaining the same olefin feed rate and aromatic to olefin ratio. Tn one embodiment a side stream from the vapor from the second column below the catalyst and olefin feed is condensed and rerouted to the aromatic make up stream from the reflux drum. The vapor pressure of the olefin in the lower end of the first column in the catalyst bed is thus increased which increases the equilibrium concentration of the olefin in the liquid phase. Tn another embodiment of the invention the effective driving force for the reaction is increased by injecting the olefin at different heights within the catalyst bed. If additional olefin is injected more catalyst bed height would be required, but the additional catalyst is more that offset by the increased throughput at the same overall olefin conversion. The practice of injecting the olefin feed at different heights is especially useful when the same olefin feed rate is used but split among the several streams because less catalyst is required.

Title: Stable pharmaceutical composition of 3-(hydroxymethyl)-5,5-diphenylhydantoin disodium phosphate ester
Inventor: HERBRANSON DALE E
IPC: A61K31/41
Filed: 1990-05-24
Abstract: Described is a stable pharmaceutical composition of 3-(hydroxymethyl)-5,5-diphenylhydantoin disodium phosphate ester, the produg of 5,5-diphenylhydantoin (phenytoin) a commonly used drug for the treatment and management of epilepsy and other types of convulsive states. It has been found that degradation of the produg to phenytoin can be controlled by controlling the pH of the composition. Controlling the pH to between 8.3 to 9.4 results in the production of diphenylglycinamide as the primary degradant and minimization of degradation to phenytoin. If the pH is maintained at a lower or higher value, then the degradation pattern changes, with earlier than expected product failure.

Title: A method of purifying air from combustible pollutants and an apparatus for performing the method
Inventor: HEED BJOERN
IPC: B01D53/44
Filed: 1990-10-23
Abstract: The invention concerns a method and an apparatus for purifying air polluted with combustible substances. In accordance with the teachings of the invention is used a device known as a ''combustion exchanger'', i.e. a device comprising an air-pervious, heat-accumulating bed in which the combustible pollutants, by reversing their direction of flow, contribute to sustaining the temperature of spontaneous combustion inside the bed in order to regenerate the regular purifying device in the form of an absorption bed. This is achieved by incorporating the latter in the channeling system of the combustion exchanger channeling system and by making heated and purified air pass from said exchanger through the absorption bed in a direction opposite to the direction of regular through-flow through the absorption bed.
