ALKYL-TERT-ALKYL ESTER SYNTHESIS REACTOR Russian patent published in 2002 - IPC

Abstract RU 2188705 C1

FIELD: devices for preparation of oxygen-containing additives for motor petrol and other additives requiring finely-dispersed bead catalysts. SUBSTANCE: unit for filtration of reaction mass from catalyst and catalyst dust is located in lower cover of reactor at distance of 200 to 300 mm from tube sheets. Filtration unit is filled with filter medium consisting of pressed metal gauzes, glass wool and/or glass fiber in form of horizontal perforated grate divided by axial and radial partitions, 50 mm high into sectors; area of each sector reaches 0.1 sq.m. filter medium is rigidly secured to perforated covers and to lower by means of bolts. Upper cover is provided with distributing baffle found at reactor inlet and made in form of truncated cones. EFFECT: enhanced mass exchange of raw material and catalyst. 2 cl, 1 dwg, 1 tbl
