两段串联浆态床费-托合成新工艺

采用中试装置对具有自主知识产权的两段串联费-托合成工艺以及传统的单段浆态床费-托合成工艺进行了模拟试验。对装置试验结果进行了数据处理和两种工艺的性能比较。在相同合成气处理量或相同装置产油量条件下，与单段浆态床费-托合成工艺比较，两段串联浆态床费-托合成工艺所需的催化剂量少20%以上，反应器单位体积有效利用率高；降低气体循环总量约60%，降低了能耗和操作费用；装置集成度高，可以减少部分设备，减少初期投资成本。

A NEW TWO-STAGE IN SERIES PROCESS OF SLURRY BED FISCHER-TROPSCH SYNTHESIS

Simulation tests of a patent two-stage in series process and conventional single-stage process for Fischer-Tropsch synthesis were carried out on a 10 L(oil)/h slurry bed reactor pilot plant system continuously,using a commercial precipitation iron catalyst.The test results show that as compared with single-stage process under the same processing capacity or oil yield,the required catalyst of this new process is less by more than 20%,the processing capacity of per unit volume reactor is much higher and a reduction of about 60% total circulating gas is observed,thus the energy consumption and operation cost are lower.This unit is more integrated and its initial investment is also lower since a few equipments,such as a recycle gas compressor can be omitted.
