    1486477 Catalyst regeneration UOP INC 19 Dec 1974 [28 Dec 1973] 54858/74 Heading B1F In catalytic regeneration apparatus, internal recycle means, e.g. comprising vertically staggered hoppers 36, conduits 37 and dipleg 38 are used to return regenerated catalyst from upper bed 18 to regeneration bed 5, the regenerated catalyst passing as a dilute phase upwardly through chamber 2 where after burning of Co->CO 2 is substantially completed, the catalyst passing via cyclone 20 to bed 18. The amount of discharge through hoppers 36 can be varied by raising or lowering the level of the bed. Specification 1486478 is referred to.

    专利说明:

    The invention relates to apparatus for regenerating a catalyst used in petrochemical industry, more particularly to apparatus used for regenerating a coked catalyst for catalytic cracking in a fluidized bed. Apparatuses for catalyst regeneration are known, containing one or several catalyst layers, a separation volume in the upper part of the apparatus and means for returning the entrained catalyst l. However, carrying out the process of regeneration of the coked catalyst in these devices is associated with limiting the afterburning of CO in order to avoid the harmful effects of high temperatures in the separation volume of the device. Such work leads to an increased CO content in the daam gas, which is thrown into the atmosphere or used as fuel. The closest to the proposed invention is a catalyst bed fluidized bed apparatus consisting of a fluid bed chamber, a separation chamber, a transport pipeline connecting both chambers, and a standpipe. The catalyst is recirculated from the separation chamber to fluidized bed 2. The disadvantage of this apparatus is that it limits the possibilities for efficiently carrying out the regeneration process with the use of a part of the combustion heat of CO. The purpose of the invention is to increase the efficiency of the process by carrying out regeneration with catalyst recycling and partial use of the heat of reaction. To this end, the transport pipeline is located inside the upper separation chamber, and the standpipe for catalyst recirculation is located inside the transport pipe. In addition, the upper separation chamber is located above the fluidized bed chamber and both chambers, the transport tailpipe and the downspout are located on a common vertical axis. The drawing shows the apparatus, a general view. It consists of an upper separation and a receiving chamber of a regenerating catalyst 1, a lower chamber 2 with a fluidized bed of catalyst 3, and a transport pipeline for gas catalysis ag.
    the mixture of the bottom 4, the standpipe 5, the means for separating the gas and the catalyst 6, the stripping section 7 of the inlet pipe 8 for fresh gas and the nozzles 9 for the output of gases, entering the spent catalyst 10 and discharging the regenerated catalyst 11.
    The device works in an odd way.
    The spent catalyst is continuously introduced through pipe 10 into the lower chamber 2 with a fluidized bed 3. A stream of fresh regeneration gas is fed to the same chamber via pipeline 8 In the fluidized bed 3, carbon deposits are oxidized and the regenerated catalyst is conveyed by pneumatic transport into transport pipeline 4, in which CO is oxidized to COg with the release of heat, which is transferred to the catalyst. The latter is separated from the gases by means of separation b and is collected in the lower part of the upper chamber 1. From here, one part of the regenerated catalyst flows back into the lower chamber 2 through the standpipe 5, and the other part through the stripping section 7 and pipeline 11 for use in the process of cracking the hydrocarbon feedstock . The efficiency of the apparatus is determined by the use of part of the heat obtained from the afterburning of CO in the trans, tailor pipeline.
