14.窒素化合物の前分離による合成原油の深度水素化精製

抄録

In order to convert synthetic crude oils (SCO) to clean motor fuels, the separation of nitrogen compounds prior to hydrotreatment (HT) was investigated. The nitrogen contents of compounds were successfully removed from light gas oil fractions (LGO) of shale oil, coal liquid and pyrolysis product of bitumen by solid extraction using CuCl_2・H_2O. The following HT greatly reduced the nitrogen and sulfur contents of products to acceptable levels for clean diesel fuel.
