HEBEI XINQIYUAN ENERGY TECH DEVELOPMENT CO.,LTD 150kt/a COAL TAR HYDROGENATING WITH FLUIDIZED BED PROJECT

In this project, the main raw materials of the process unit were the low temperature coal tar, high temperature coal tar, anthracene oil, poor quality crude oil and residual oil. Coker gas oil, coking slurry, shale oil and other poor quality heavy oil could also be processed. Take coal tar as example, this new technology process achieved hydrogenation for full range distillate. The nitrogen removal rate of fluidized bed reaction >80%，desulfurization rate>80%, colloid and asphalt product conversion rate>90%，liquid product yield>95%. The unit has activated in July 2015, and all products qualities were compliant with national standards. And now the running is very well. 

This unit used the fourth generation technology of coal tar lighting with fluidized bed process (EUU) and“NUHC-60”series of catalyst, which two technologies researched and developed independently by New-unity Company. Compare to coal tar lighting with fixed bed, the fourth generation technology (EUU) has a wider range of selective for raw materials, high conversion efficiency, and has advantages of smaller difference of pressure of reactor, lower ratio of hydrogen and oil , higher  GHSV and rate of thermal energy utilization. This process unit was liable to large-scale, and catalyst could be added and removed while the process unit was running，and the cost of investment and operating could be decrease.
