摘要： A catalyst regeneration process and apparatus for the oxidative removal of coke from a coke contaminated fluid catalyst. The process comprises a high temperature coke combustion zone, a catalyst disengagement zone and an external heat removal zone comprising a shell and tube heat exchanger. Catalyst is cooled by passing it through the shell side of the heat exchanger with a cooling medium through the tube side. A mixture of coke contaminated catalyst, oxygen containing gas, and cool regenerated catalyst from the heat removal zone are contacted in the high temperature combustion zone, the temperature of which is controlled by adjusting the rate at which catalyst is passed through the heat exchanger. This rate is adjusted by adjusting the difference in catalyst head between the catalyst inlet and outlet of the heat exchanger and thus the hydraulic driving force which effects catalyst circulation through the heat exchanger.

摘要： The invention relates to an improvement in an integrated, two stage coking and steam cracking process for the production of unsaturated light hydrocarbons. A heavy hydrocarbonaceous oil is first coked in a fluid coking zone. High temperature cracking in the presence of steam is carried out on the vaporous coker conversion product by injecting into the vapors a stream of hot coke particles at a sufficient temperature and in sufficient amount to raise the coker vapors to steam cracking temperature and supply the endothermic heat of reaction. Solids are separated from gas in a gas-solids separation zone such as one or more cyclones and sent to the fluid coking zone and the gas is quenched to stop olefin degradation reactions. According to the improvement, a portion of the separated solids is diverted from entering the fluid coking zone so that the amount of separated solids it receives is only sufficient to satisfy its heat requirement. Solids may be diverted via the cyclone dipleg. An internal standpipe connected to the cyclone dipleg and having a valve and associated riser may be used to regulate the amount of separated solids permitted to enter the fluid coking zone.
摘要翻译：本发明涉及用于生产不饱和轻烃的综合两阶段焦化和蒸汽裂解方法的改进。重质含油油首先在流体焦化区焦化。在蒸汽存在下进行高温裂解，在蒸气焦化转化产物中，通过在足够的温度和足够的温度下将热焦颗粒流注入蒸气中，以将焦化器蒸气升至蒸汽裂解温度并提供吸热热的反应。固体在气体 - 固体分离区如一个或多个旋风分离器中与气体分离，并送到流体焦化区，并将气体淬灭以停止烯烃降解反应。根据改进，一部分分离的固体被转移进入流体焦化区，使得其接收的分离的固体的量仅足以满足其热需求。固体可以通过旋风di be进行转移。连接到旋风分离器三通并具有阀门和相关联的提升管的内部立管可用于调节允许进入流体焦化区域的分离的固体的量。

摘要： The present invention is for a continuous system wherein spent catalyst is removed from a regeneration vessel, while fresh catalyst is added in order to maintain proper catalyst activity in a hydrocarbon processive system. The withdrawal of the spent catalyst must be achieved at a steady flow rate which is compatible with the introduction of fresh catalyst of the hydrocarbon processing system. This flow rate is controlled by a downstream pressure and venting control in the spent catalyst hopper stage acting in conjunction with a novel flow restriction zone in a discharge conduit.

摘要： A catalyst regeneration apparatus for the oxidation of coke from a spent catalyst, said coke being converted to CO, and for the conversion of the CO to CO.sub.2. Hot regenerated catalyst is recycled from a dense bed in the regeneration zone to mix with incoming spent catalyst in a mixer zone. The mixer zone operates in dense phase and is supplied with a relatively small amount of a fluidizing medium, preferably air. After the mixing of spent and fresh catalyst is substantially completed, a relatively large amount of a regenerating gas, preferably air, is admixed with the catalyst mixture, and some coke oxidation occurs. The balance of coke oxidation takes place in a downstream-situated regeneration zone of substantially conventional design. There is a transfer section connecting the mixer zone to the regeneration zone through which the relatively large amount of the regenerating gas is admitted. The transfer section is preferably a frustoconical surface, the horizontal cross section of smallest perimeter of which adjoins the outlet of said mixer zone, and regenerating gas addition is made at the base of the transfer section in order to provide a venturi effect which ensures good air-catalyst mixing.

摘要： An improved industrial multistage recirculating-fluidized-bed reactor for producing chlorine and iron oxide having an initial "dense" zone and a downstream "dilute" zone. In the dense zone, a fuel is burned, reactants and recirculated iron oxide particles are heated, ferric chloride is vaporized and at least 50% of the ferric chloride is converted to chlorine and iron oxide. In the downstream dilute zone, a solids fraction from 0.005-0.05 is maintained, along with a superficial gas velocity from 1.5-6 meters/second which is from 5-25 times the superficial gas velocity in the dense zone, and the conversion of ferric chloride is continued to greater than 95% completion.

摘要： An apparatus is disclosed in which a raw material feed delivery pipe is connected to the periphery of a vertical conduit that receives gases from a rotary kiln and conducts such gases upwardly to a location where the gases are divided between a pair of cyclone gas-solids-separator heat exchangers comprising a first stage of raw material preheating. An axially movable and rotatable sleeve is mounted over the discharge end of the pipe, and the sleeve is provided with a terminal nozzle portion curved to discharge raw material at an obtuse included angle to the axis of the delivery pipe. A method is disclosed by which the sleeve is moved along the pipe and rotated relative to the pipe, to change the nozzle discharge location and deflection angle relative to the rising gas stream, until an equal temperature drop of gases in both heat exchangers is achieved and balanced loading thereof is thereby indicated.
