| 摘 要： | 以中国石化高桥分公司3号酮苯脱蜡装置加工的减二线和减五线蜡下油为原料，分别采用低温发汗和酮苯脱蜡脱油试验的方法，从轻馏分（减二线）的蜡下油中，得到了固态烃化学组成以正构烷烃为主的低熔点石蜡，从重馏分（减五线）的蜡下油中，得到了固态烃化学组成以大量的环烷烃和异构烷烃为主的低熔点微晶蜡。对低熔点石蜡分析结果表明，该石蜡具有吸热温度范围窄、吸热量高、相变温度和峰顶温度适中等特点，可以开发为相变石蜡产品。同时，低熔点微晶蜡的化学组成较好地解释了一直以来工业生产中一段脱蜡二段脱油工艺"对轻馏分效果好，而对重馏分效果差"的现象，为今后生产高熔点、低含油量石蜡方案提供了依据。

| Abstract: | Two foots oil samples from processing 2nd and 5th vacuum side cuts at the No.3 ketone-benzol dewaxing unit of SINOPEC Shanghai Gaoqiao Branch were used as feedstocks and treated by low temperature sweating deoiling and solvent dewaxing-deoiling respectively.From the source of light fraction(2nd vacuum side cut),low melting point wax was obtained,its solid hydrocarbons were mainly consisted of normal paraffins.The thermal analysis of this low melting point wax showed that it exhibited the characteristics of ... |
