In conventional fluidized granulators whose housing is made of a steel plate, a powder tends to cause blocking if it is highly hygroscopic, and the bag filter used therein causes clogging. These problems have been solved in the present invention by forming the housing of a fluidized granulator with a porous membrane in place of the conventional steel plate. This fluidized granulator produces granules or a coated powder by spraying powder with water, a binder fluid or a coating fluid while maintaining the powder in a fluidized state.

In a process for the production of aluminium chloride by condensation of gaseous aluminium chloride in a fluidised bed of aluminium chloride particles, the gaseous aluminium chloride is introduced into the bed at an inlet speed of 18 m/s to 90 m/s. The size of the particles of aluminium chloride in the bed is also maintained at less than 500 microns by periodically removing the larger particles which stay in the lower part of the fluidised bed. The aluminium chloride obtained has a purity enabling it to be used in an electrolytic reduction process for the production of metallic aluminium.

A slurry Fischer-Tropsch hydrocarbon synthesis process for synthesizing liquid hydrocarbons from synthesis gas, in a hydrocarbon synthesis reactor, also hydroisomerizes the synthesized hydrocarbons in one or more external downcomer reactor hydroisomerizing loops outside of the reactor, but which are a part of the synthesis reactor. A monolithic catalyst is used for the hydroisomerization, and slurry circulation between the synthesis reactor and the one or more hydroisomerization loops is achieved, at least in part, by density-difference driven hydraulics created by removing gas bubbles from the slurry passed into the loop. Preferably, catalyst particles are also removed before the slurry contacts the monolithic hydroisomerization catalyst.

Method and device for ethylene polymerisation

Номер: RU2394842C2

FIELD: chemistry. ^ SUBSTANCE: present invention relates to a method for polymerisation of ethylene or copolymerisation of ethylene with other 1-olefins. The invention describes a method for polymerisation of ethylene or ethylene with other 1-olefins in accordance with which ethylene polymerises in the presence of a catalyst in a gas-phase reactor (1) with formation of polymer particles. In order to tap polymerisation heat, there is a circulating reaction gas which contains propane and non-polymerised ethylene in which polymer particles are continuously or discretely output from the reactor (1). Polymer particles are separated from the larger portion of the accompanying gas and degassed. Gas is released from the captured fine particles. Gas is separated from the low-boiling fraction which contains ethylene or from the high-boiling fraction which contains other 1-olefins or alkanes with 4-12 carbon atoms at the first separation step. The propane fraction is separated at the second separation step and then used to degas polymer particles coming from the reactor, where partial pressure of ethylene in the propane fraction used for degassing is less than 6000 Pa under degassing conditions, and total partial pressure of other 1-olefins and alkanes with 4-12 carbon atoms in the propane fraction is less than 10000 Pa.

Methods of changing polyolefin production conditions to mitigate small gels in a polyolefin article

The number of small gels that form in polyolefin thin films may be reduced by altering certain production parameters of the polyolefin. In some instances, the number of small gels may be influenced by the melt index of the polyolefin. However, in many instances, melt index is a critical part of the polyolefin product specification and, therefore, is not manipulated. Two parameters that may be manipulated to mitigate small gel count while maintaining the melt index are polyolefin residence time in the reactor and ICA concentration in the reactor.
