摘要： A process for the regeneration of a sulfur containing catalysts, wherein the catalyst is stripped of sulfur before the oxychlorination treatment of the regeneration process, typically before the catalyst is sent to the regeneration zone. The process is particularly useful for catalyst employed in hydrocarbon conversions such as dehydrogenation reactions, particularly those which comprise the injection of sulfur and/or at least one sulfur compound before or simultaneously to the introduction of the charge into the first reaction zone.

摘要： A continuous process for the dehydrogenation of paraffinic and olefinic hydrocarbons in the presence of a catalyst comprises circulating a charge containing said paraffinic hydrocarbons through at least two reactions zones of the moving bed type which are arranged in series, the catalyst flowing successively in each reaction zone. The catalyst which is drawn off from the last reaction zone is sent to a regeneration zone at the exit from which it is reintroduced close to the first reaction zone. The process comprises the injection of sulphur and/or at least one sulphur compound before or simultaneously to the introduction of the charge into the first reaction zone. In accordance with the process, the catalyst which is drawn off from the last reaction zone is sent into a stripping zone wherein the sulphur which it contains is removed before the catalyst is sent to the regeneration zone.

摘要： Continuous process for the skeletal isomerization of n-olefins containing at the most 20 carbon atoms, in the presence of a catalyst essentially constituted by alumina and titanium, in which a charge containing the said n-olefins is made to flow through at least one fluidized bed reaction zone, the catalyst flowing into each reaction zone. The catalyst drawn off from the final reaction zone is passed into a regeneration zone, at the outlet of which it is passed into a zone where it undergoes a steam treatment prior to its reintroduction into the first reaction zone. The process is performed in the presence of steam, so that the catalyst is in contact with 3 to 85 wt. % (based on the catalyst weight) of steam. The water/olefin charge molar ratio in the reaction zone is between 0.1 and 3.

摘要： An enclosure in which there circulates a moving bed of solid particles (for example a moving-bed catalytic reactor such as a reforming reactor), is delimited in the enclosure by at least one grill. In the enclosure a fluid passes through the bed in a direction different from that of the flow of the assembly of the particles and issues from the bed by way of at least one grill. Disposed in the thickness of said bed in an intermediate wall (grill) such as to distribute the thrust forces produced by the fluid on the particles in the zones of the bed which are delimited in that way. Jamming of the particles against the grill or grills is greatly reduced and the admissible fluid flow rate is then decreased.
