REACTOR WITH AIR-FLUIDISED BED, THREE-PHASE REACTOR AND PROCEDURES FACILITATING THEIR OPERATIONS (VERSIONS) Russian patent published in 2010 - IPC B01J8/22 B01J19/24 C10G2/00 

FIELD: power industry.

SUBSTANCE: invention refers to reactors with air-fluidised bed. One of the versions discloses the procedure facilitating operation of a two-phase reactor with fluidised bed, which consists in low-level supply of at least one gaseous reagent into vertical directed air-fluidised mass of solid particles. Also air-fluidised mass is present in at least two vertically arranged neighbour columns located inside a common shell of the reactor. Each column is divided into a multitude of vertically running channels. At least part of the channels is inter-communicated with flow of air-fluidised mass. Notably, air fluidised mass is present in at least some of the channels. At least some of the columns and/or channels are limited with surfaces of heat exchange. Further, the procedure consists in creating conditions for reaction of the gaseous reagent, when it rises through air-fluidised mass present in at least some of the channels of the columns. Thus, there is produced a gaseous product. Successively, the procedure consists in creating conditions for extracting the gaseous product and/or not-reacted gaseous reagent from air-fluidised mass in head free space above air-fluidised mass, and in removing the gaseous product and not-reacted gaseous reagent, if present, from head free space. The disclosed designs of the reactors have large areas of heat transfer surfaces and limit degree of undesirable reverse mixing, owing to which there is potentially possible to obtain optimal combination of desired characteristics of plug flow (facilitating high efficiency and good selectivity) and characteristics of good mixing (required for wanted distribution of solid particles and for uniform temperature profiles).

EFFECT: invention essentially reduces risk of zooming at conversion of prototype to industrial installation.
