摘要
介绍了一种以炭黑改性的γ-Al2O3为载体的柴油加氢降凝预精制催化剂DHT-1,活性评价结果显示其加氢活性略好于参比剂。该催化剂与柴油异构降凝剂组合活性考察结果为:以大庆焦化柴油为原料,柴油收率在93.0%以上,产品硫含量小于50.0μg/g,凝点降低最高达19.2个单位,十六烷值提高1.0~3.4个单位。以上结果表明,DHT-1能与异构降凝剂较好地匹配使用。
The DHT-1 hydrorefining catalysts for diesel oil hydrogenation based on γ-Al2O3 modified by carbon black is introduced. The envaluation results showed that its hydrogenation activity was a little better than the reference catalyst. When combining it with a kind of hydrodewaxing catalyst for processing Daqing diesel oil, the tests results showed that the yield of diesel fuel was more than 93.0 wt%, the sulfur content was lower than 50.0μg/g, the freezing point was lower by 19.2℃, and the cetane number increased by 1.0 to 3.4. All of these show that the DHT-1 catalyst can be well matched with the hydrodewaxing catalysts.
