MIXING FEED RESERVOIR SYSTEM Russian patent published in 2016 - IPC B01J38/02 B01J8/18 B01J38/30 B01J8/26 C10G11/18 C07C4/06 C10C3/02 G05D11/00 

FIELD: chemistry.

SUBSTANCE: invention relates to improved systems and methods for storage of suspensions and handling thereof. Feed reservoir of system for storage of suspension, including hydrocarbons and catalyst, comprises a reservoir for storage, having a first end, inclined towards inlet for recycling, a second end and at least one wall surrounding inner volume between first and second ends; suspension inlet communicated with internal volume, suspension inlet is located between first end and second end of said reservoir; outlet communicated with internal volume, outlet is located between first end and inlet for suspension; said recycling inlet communicated with inner volume of first end of storage reservoir, recycling inlet is located in lower point and/or in lowest point of inclined bottom; pump with a suction line communicated with outlet; a recycling valve communicated with discharge line of pump and inlet for recycling; outlet valve communicated discharge pump line; and a flow deflector inside said reservoir, arranged to redirect flow between inlet for suspension and inlet for recycling. Invention also relates to a cracking system with a fluidised catalyst, comprising a cracking lift-reactor with fluidised catalyst made to ensure reaction of hydrocarbon with catalyst to obtain a product; a cooling tower in fluid communication with cracking lift-reactor with fluidised catalyst and configure to mix product with cooling oil; filtration system in fluid communication with cooling tower and configured to remove suspension of fuel oil from cooling oil; service container system in fluid communication with filtration system, a regenerator, configured to feed catalyst in cracking lift-reactor with fluidised catalyst.

EFFECT: in said systems for storage of solid substances remain suspended in oily suspension.
