SYSTEM AND METHOD OF PUTTING CATALYST AND/OR ADDITIVE INTO FLUIDISED CATALYTIC CRACKING INSTALLATION Russian patent published in 2009 - IPC C10G11/18 B01J8/00 

FIELD: chemistry.

SUBSTANCE: system for putting catalyst and/or additive into a fluidised catalytic cracking installation comprises: a dust collector in a system for linking fluid medium with at least one storage container, containing one catalyst and/or additive; device for creating vacuum in the system for linking fluid medium with the dust collector which creates a vacuum inside the dust collector, and under the effect of the vacuum, one of the catalysts and/or additive is sucked into the dust collector; and a transfer cup in the system for linking fluid medium with the dust collector, for receiving one of the catalysts and/or additive from the dust collector; the transfer cup is in the system for linking fluid medium with fluidised catalytic cracking installation and with a source of compressed air, such that, one of the catalysts and/or additive is forced into the fluidised catalytic cracking installation under the effect of pressure fall between the transfer cup and the fluidised catalytic cracking installation; and one or more strain sensors for measuring weight of the dust collector, transfer cup or one of the catalysts and/or additive, sucked into the dust collector.

EFFECT: simple implementation and preservation of quality of catalyst when carrying out the process.
