提出酮苯原料预加氢生产高熔点石蜡的工艺路线，与原生产工艺相比，减四线含油蜡一段脱油滤速可以提高１６ ．６ ％ ～２６．８ ％ 。
The process route of pre-hydrogenation of ketone and benzene to produce high melting point paraffin wax is proposed. Compared with the original production process, the de-oiling filtration rate of oil-containing wax reduced by four lines can be increased by 16%. 6% ~ 26.8%.
