摘要： A method and apparatus for replacing particles in a process that transfers particles is disclosed. This invention employs a seal zone which is in communication with two zones of the process and in which particles that are being added to the process are purged. This invention allows particles to be replaced without reducing the normal rate of particle transfer through the process, which results in a savings in downtime costs. This invention is adaptable to a multitude of processes for the catalytic conversion of hydrocarbons in which deactivated catalyst particles are regenerated.

摘要： A regeneration process is described that eliminates or greatly reduces thermal channelling in a cooling zone bed. The method controls the flow rate of cooling gas independently of the requirements of the regeneration process for combusting coke and for halogenating or drying the catalyst. In one embodiment, a portion of a cooling stream is bypassed around a cooling zone and then passed to a drying zone. In another embodiment, one portion of a cooling stream from a cooling zone is vented, and another portion of the stream is passed to a drying zone.

摘要： A controlled method of changing the transport rate of particles between two zones is disclosed. Changes are made in a computed value of the pressure difference of the conduit between the two zones through which the particles are transported. The changes are of a predetermined magnitude and are performed at predetermined time intervals, until the desired final value of the pressure difference is reached. The method minimizes fluctuations in the pressures of the two zones without over-sized vessels or additional equipment that would otherwise be needed to accommodate pressure changes. This results in a savings in construction costs. This invention is adaptable to a multitude of processes for the catalytic conversion of hydrocarbons in which deactivated catalyst particles are regenerated.

摘要： A controlled method of transporting catalyst between two zones while inhibiting communication between the atmospheres of the zones is disclosed. Communication between the zones is inhibited by controlling pressure differences. The two zones are separated by a means to lift catalyst, which results in a savings in construction costs. This invention is adaptable to a multitude of processes for the catalytic conversion of hydrocarbons in which deactivated catalyst particles are regenerated.

摘要： Increased yields of LPG and middle distillate products are obtained in a two stage hydrocracking process by the use of a catalyst containing a beta zeolite. In embodiments, the beta zeolite has not been hydrothermally treated or has been hydrothermally treated at a relatively low temperature. In another embodiment, the catalyst contains a relatively low amount of beta zeolite.
