With heavy aromatics ( C 8 or above) extracted from catalytic light diesel fuel as feedstock and sulfuric acid as catalyst, the preparation of aromatic-formaldehyde polycondensation resin has been introduced in this paper. 本文介绍了以催化裂化轻柴油抽提C8以上重芳烃为原料,硫酸为催化剂,芳烃&甲醛缩合制树脂的方法。
Technical measures were taken in the 2Mt/ a heavy oil FCCU in Yanshan Petrochemical Corporation for more LCO production to meet the increasing market demand of diesel fuel. 根据市场对柴油的需求,在燕化2Mt/a重油催化裂化装置上进行了增产柴油的技术攻关。
Because of much difference in physical and chemical characteristic compared with light diesel oil, heavy diesel fuel makes many problems in fuel combustion on those engines. 但由于重质燃料油与轻柴油在燃油理化特性等方面具有明显差别,在缸内燃烧方面仍然存在许多问题。
