Title:
LIQUID LEVEL DETECTING APPARATUS IN THREE-PHASE FLUIDIZED REACTION APPARATUS SUCH AS BOILING BED REACTOR
Document Type and Number:
Japanese Patent JPS60147230
Kind Code:
A
Abstract:

PURPOSE: To make it possible to prolong the life of a catalyst and to extend an operation time, by providing a nozzle, which has a nozzle cleaner mounted therein, for connecting the liquid phase part in a reaction apparatus and a liquid sump tank while arranging a as pressure liveling pipe.

CONSTITUTION: The interior of a three-phase fluidized reactor 1 consists of a dense catalyst bed 12, a loose catalyst bed 13, a gaseous layer 14 and boundary phases 6, 7. The dense catalyst bed 12 mainly comprises freely fluidized catalyst particles and the loose catalyst bed 13 almost consists of a reaction liquid and gas. In the reactor 1, a large amount of a liquid is formed into a rising stream from a fluidizing plate 11 for efficiently performing the fluidization of the catalyst bed 12 is freely fluidized. The liquid supplied to a recirculation pump 3 is efficiently separated from gas and the catalyst by a catalyst/gas phase separator 5 and recirculated to the recirculation pump 3 through a nozzle 4. A pressure leveling pip 18 connects a liquid sump part 15 and a nozzle 9 to uniformize a pressure level.
