Domestic And Industrial Applications Of β Zeolite Catalyst For Cumene Synthesis

In this paper, domestic and industrial applications ofβzeolite catalyst for cumene synthesis were studied. Technology of Dalian Technology University was used for catalyst preparation, the SB powder as the aluminum source, silica sol as the silica source, tetraethyl ammonium bromide as template agent and ammonia as additives, in the presence of sodium hydroxide and other alkali by hydrothermal synthesis, synthesis of (3 zeolite catalyst. The influence of reaction temperature, pressure, benzene/propylene ratio, space velocity and other factors on the alkylation reaction of hydrocarbons to optimize reaction conditions. Using industrial materials, single reactor synthesis of P zeolite 100 kg. In the cumene alkylation reactor unit hanging lateral line, as close as possible under the conditions of plant production and to investigate the catalytic activity and life. Lateral line experiments were loaded catalyst 100 kg, the catalyst for the future application of industry testing provides a reliable basis. Reactor using 8 m3 synthesis of (3 zeolite improve the stability of the catalyst, reduce the multi-batch fluctuations caused by the catalyst. In the case of catalyst performance guarantee and improve the yield of the catalyst. Industrial application of zeolite catalysts to achieve localization of the catalyst for enterprises to create a significant economic and social benefits of technological progress and make greater contribution.
