摘要： An immersion fixed bed reactor intensified by liquid flow contains a cylindrical tank R-1 internally installed an annular cylindrical catalyst bed (ACCB) T-1 packed with solid catalysts. The inner and outer walls of the T-1 are composed of two layers of stainless steel sheets with holes. The outer layer of stainless steel perforated with holes. The inner layer of catalyst contacting stainless steel is covered with stainless steel waved mesh in circumferential direction. The bottom of T-1 is sealed with a steel plate by welding or a blind plate and the top of T-1 is fixed to R-1 with a flange. The solid catalysts are packed in the ACCB. The cylindrical tank R-1 is equipped with a reaction mass inlet duct 1 at the top and mass outlet duct 2 at the bottom and the duct 2 is connected with a liquid circulating pump P-1, a liquid outlet duct valve V-1, a flow meter L-1, a heat exchanger E-1 and a normal tube inlet M-linserting into the central column space of T-1 at axial position through the top of R-1, and enables the liquid is pumped by P-1 into the central column space of T-1 and radically pass through the catalyst bed of T-1 into the space between R-1 and T-1, thus one cycle of reaction operation is accomplished. With the continuous work of the pump P-1 the liquid in R-1 will be repeatedly circulated and the reaction is simulanously carried out again and again. if it is gas-liquid-solid reaction system, the above-stated normal tube inlet M-1 will be substituted by a jet inlet M-2 which has a vacuum inlet tube allowing the surrounding gas or mass vapor sucked and mixed with the liquid into the central column space of T-2, then radially flows together with liquid reactants through the catalyst bed of T-1 into the annular space between R-2and T-2. The vacuum inlet tube of M-2 is connected to the outlet tube of R-2 and the gas reactant is added through the gas inlet and a gas distributor.

摘要： This invention relates to a process of integrated system formed by coupling of fixed bed, jetting floating bed, and separating unit, aimed to provide a new process and equipment of higher efficiency, which integrates multi-type reactors and separation. In this invention, reaction materials will undergo preliminary reaction in fixed bed reactor and intensified reaction in jetting floating bed reactor, and then separation in the subsequent separation system. Unreacted materials will be returned to the raw material intermediate storage tank for mixing with fresh materials, as raw materials for continued reaction. During this process, materials first pass the fixed bed reactor once to achieve certain conversion rate, and then enter the jetting floating bed reactor for intensified reaction. When the product reaches required concentration, the materials will enter subsequent separation equipment for separation. During the whole process, fixed bed reactor, jetting floating bed reactor, and subsequent separation system are coupled, so that the flow path is more integrated, reaction time is greatly shortened, and process energy consumption is further lowered.
