| 4467045 | Redispersion of Ir catalysts by low temperature reduction step A process is described for the redispersion of iridium-containing catalysts involving a low temperature hydrogen reduction step, i.e., from 190° C. up to about 250° C. after a coke burn-off. The low temperature reduction step allows milder conditions du... | 08/21/1984 |
| 4447553 | Process for re-activation of solid acid catalyst A process is disclosed for re-activating a used solid acid catalyst wherein the catalyst is calcined to burn off heavy hydrocarbons and subsequently halogenated with chlorine and/or fluorine or their compounds entrained by an inert gas or a non-reducing g... | 05/08/1984 |
| 4438288 | Dehydrogenation of hydrocarbons with a halogen contacting step This invention relates to a new process for dehydrogenating hydrocarbons utilizing a catalyst comprising a platinum group component, an alkali or alkaline earth component and a porous support material. After the catalyst is used to dehydrogenate hydrocarb... | 03/20/1984 |
| 4429177 | Method of oligomerizing 1-olefins and regenerating a heterogeneous catalyst An alpha-olefin is oligomerized in the presence of a three-component catalyst comprising a particulate solid adsorbent, boron trifluoride and elemental oxygen. The process also activates the catalyst. For example, 1-decene is oligomerized to a product pre... | 01/31/1984 |
