Hydrogenation of organic sulphides, nitrides, chlorides, and olefins in hydr ocarbon production streams as secondary process low grade gasoline and kerosene to produce Low sulfur and low aromatic hydrocarbon kerosene. In the middle or low pressure, Hydrogenation of the catalytic diesel of pipe transportation crude oil ( for example Shengli, Liaohe, Xinjiang, Central plains, Gudao, Luning) and catalytic diesel of mixing of vacuum residuum and coker disel. The effect will come off satisfactorily. Product Characters Good catalysis activity for sulphides, nitrides, olefins and colloid removal Free of easy bleeded active constituent, so would not happen equipment corrosion Chemical Composition Active metal, auxiliaries and alumina Packing Paper-board drum liner with plastic bags which suit for all kinds of transportation. Each Drum Net 25kgs. Load and lay carefully in transportation, do not destroy the package, avoiding rain. Storage in shady and cool, low-temperature and dry location. Period of quality assurance is 2 years in normal temperature.
