摘　　要：简述了国内外降凝剂发展概况,分析了南阳石蜡精细化工厂生产的柴油对目前国内外降凝剂感受性差的主要原因,选择PCH降凝剂作为高含蜡柴油降凝剂。实验及工业应用表明,PCH降凝剂能有效地降低该厂柴油的冷滤点,当加入量为0.05%,调合柴油的冷滤点下降4℃,满足了油品的使用标准；并使柴油收率提高2%,经济效益明显。PCH降凝剂与现行国内外降凝剂产品相比,具有独特效果,对高含蜡柴油具有极好的推广应用价值。The development of pour point depressant for diesel oil at home and abroad was described. The main reasons for poor sensivity of pour point depressant to diesel oil produced by Nanyang Wax Fine Chemical Plant were analyzed and PCH pour point depressant was selected in diesel oil containing more paraffin wax. The laboratory and industrial application showed that PCH could effectively decrease the cold filter plugging point of diesel produced by the plant. The cold filter plugging point was decreased by 4 ℃ meeting the the requirements of the oil and furthermore the yield of diesel oil was decreased by 2 % with obvious economic benefit. Comparing with current pour point depressants at home and abroad, PCH pour point depressant had special effects and could be widely used in paraffin wax with more content of wax.
