  摘要：

  使用聚（n-C.sub.24）烷基甲基丙烯酸酯聚合物脱蜡剂与较低熔点的聚（C.sub.8-C.sub.20）烷基甲基丙烯酸酯聚合物脱蜡剂相结合，可以改善蜡状碳氢油的溶剂脱蜡。使用此组合脱蜡剂改善的溶剂脱蜡过程是采用表面冷却间接换热器或使用冷溶剂直接冷却的增量和总预稀溶剂型过程。采用通常液态脱蜡溶剂的溶剂脱蜡过程，例如C.sub.3-C.sub.6酮，例如甲基乙基酮，甲基异丁酮和它们的混合物，酮与芳香族化合物的混合物，例如MEK/甲苯，卤代C.sub.2-C.sub.4碳氢化合物，例如四氯乙烷，三氯乙烯等。采用低沸点、通常为气态的碳氢化合物，例如丙烷、丙烯、丁烷、丁烯和这些溶剂的混合物，与上述酮，例如丙烷/MEK等，也受到本脱蜡剂组合的益处。使用组合脱蜡剂可以改善脱蜡过程中的进料过滤速率和液体/固体比率。
