Patent MX-9804313-A (MX)
Title: Process for preparing a catalyst suitable for use in isomerising hydrocarbons, the catalyst thus obtained, and its use.
Inventor: HEINERMAN JACOBUS JOHANNES LEO
IPC: B01J37/24
Filed: 1998-05-29
Abstract: The invention pertains to a process for preparing an activated catalyst composition in which a catalyst composition comprising a Group VIII noble metal and a hydrocarbon-substituted aluminium compound on an alumina carrier containing up to 20 wt.percent of other components is activated by being contacted with a hydrogen-containing gas at a temperature in excess of 500 degree C, with the proviso that at least when the hydrocarbon-substituted aluminium compound present in the catalyst composition is not a hydrocarbon-substituted aluminium halide, the catalyst composition to be activated is contacted with a halogen compound either prior to or during the activating step. The catalyst obtainable by this process and the use thereof in hydrocarbon conversion processes, such as isomerisation and alkylation processes, are also part of the present invention. The effect of the high-temperature activation step is that the activity of the thus obtained catalyst is improved in comparison with a catalyst of the same composition which has not been subjected to said high temperature activation step.

Title: Process for producing a particulate laundry additive composition for perfume delivery.
Inventor: ANGELL ADRIAN JOHN WAYNFORTH
IPC: C11D17/06
Filed: 1998-08-06
Abstract: The invention provides a process for producing a particulate laundry additive composition. More particularly, the process produces a particulate laundry additive for perfume delivery in laundry detergent compositions, especially those in the form of granules or agglomerates. The process includes mixing a porous carrier material, typically containing perfume, and an encapsulating material, typically a carbohydrate material, to form agglomerates or an extrudate which is then sized into particles for incorporation into a detergent product. The process may be employed to produce particulate additive compositions which may be used in fabric softening and diswhashing as well as laundry detergent compositions.
