    摘要: This invention relates to efficiently regenerating catalyst particles by minimizing the formation of localized “hot spots” and “cold spots” in a regeneration zone. In one embodiment, the invention includes mixing spent catalyst from a reactor and cold catalyst from a catalyst cooler in a mixing zone and directing the mixed catalyst to the regeneration zone in a fluidized manner with a fluidizing medium. In the regeneration zone, the mixed catalyst contacts an oxygen-containing regeneration medium under conditions effective to regenerate the spent catalyst contained therein.

    摘要: An HF alkylation process for producing gasoline boiling range alkylate product by the alkylation of a light olefin with an isoparaffin in the presence of hydrogen fluoride as an alkylation catalyst, in which the content of organic fluorides in the alkylation product stream is reduced by recontact with additional HF alkylation acid after which the hydrocarbon phase and the denser acid-containing phase are separated in a hydrocyclone. The use of the hydrocyclone enables the acid inventory of the unit to be significantly reduced which still achieving satisfactory removal of the unwanted fluoride by-products.

    摘要: The present invention is an improved regenerated catalyst bend assembly for a fluid catalytic cracking unit. In a preferred embodiment, the reduced elevation (“RE-bend” or “REL-bend”) regenerated catalyst return line assembly of the present invention has an outlet elevation that is lower than the inlet elevation of the RE-bend or REL-bend regenerated catalyst return line assembly, and a process for utilizing the assembly in a fluid catalytic cracking unit. The present invention is especially useful in the modification of existing fluid catalytic cracking units to lower the elevation of the outlet of the regenerated catalyst return line assembly, thereby providing needed space to increase the fluid catalytic cracking reactor riser length.

    摘要: A sulfuric acid-catalyzed alkylation reactor system is provided for alkylating isoparaffins with olefins to produce hydrocarbon alkylates. The reactor vessel has a vertical cylindrical wall, a top, an inverted conical bottom portion, internal perforated baffles and multiple emulsion injection inlet pipes, disposed tangentially to and communicating with the interior of the reactor vessel. The emulsion injection inlet pipes have static mixers incorporated therein and tangential injection of the emulsion imparts a circular motion to the contents of the reactor vessel, resulting in partial phase separation of the reacted products. The reactor vessel communicates with a settling vessel through a transfer pipe having a vertical portion suspended within the central portion of the reactor vessel and a horizontal portion sealably extending through the cylindrical wall of the reactor vessel. The transfer pipe has a first end near the conical bottom portion of the reactor vessel and a second end at a top portion of the settling vessel. The reactor system enables a sulfuric-acid catalyzed reaction of olefins with isoparaffins utilizing static mixing of the reactants, and minimizing leakage of the reactants to the environment.
