摘　　要：通过对低温浆态床费托合成反应工艺特性和反应器性能要求的分析,为有利于蜡抽出系统的设计和维护、催化剂和反应温度在反应器床层的均匀分布,提出了浆液自行外循环固液分离浆态床反应器设想。通过气速对催化剂颗粒沉降、携带的影响,气体分布器对气含率的影响,浆液自行外循环推动力等因素分析,采用流体动力学、传热模型和宏观费托合成反应动力学模拟计算,确定了浆态床反应器的尺寸,以及进料分布器、内取热列管等内构件结构以及气固分离设备的结构,开发出了应用于低温费托合成外循环浆态反应器。Through the analysis of reactor characteristics and performance requirements of the low-temperature slurry phase Fischer-Tropsch synthesis reaction process,to be helpful to wax-out system design and maintenance,and uniform distribution of catalyst and reaction temperature in the reactor bed,the idea of slurry external self circulation solid-liquid separation slurry reactor is proposed.Through the factor analysis of gas velocity’s influence on catalyst particles settlement and carrying,the effects of gas distributor on the impact of gas holdup,and the driving force of slurry external self circulation,fluid dynamics,heat transfer model and the macro-kinetics of Fischer-Tropsch synthesis simulation are adopted to determine the slurry reactor size,as well as the inner structural components of feed distributor,hot tubes,etc and the structure of gas-solid separation equipment to develop the application of low-temperature Fischer-Tropsch synthesis external circulation slurry reactor.
