Improved H₂SO₄‐catalyzed alkylation reaction in a rotating packed bed reactor by adding additives

Abstract

The isobutane/butene alkylation process catalyzed by an acid solution is widely used to obtain high octane number gasoline components. However, limited by the mass transfer and mixing of the acid solution and the hydrocarbon liquid-liquid system, the product performance needs to be improved.

Three-dimensional gas-liquid flow simulation of a rotating packed bed using Eulerian porous media models

“…As a representative equipment for process intensification, the Rotating Packed Bed (RPB) is characterized by high mass transfer efficiency, small size, light weight, low energy consumption, good operational flexibility, and ease of scale-up [2,3], which make RPBs uniquely advantageous for mass transfer limited reactions and combinations of several unit operations in one apparatus [3]. Currently, RPBs are widely applied for process intensification of various reactions and separations such as organic pollutants degradation [4], catalyst preparation and application [5,6],…”
