摘要:
A process for obtaining a wax fraction from a feed wax, the pro- cess comprising: (a) providing a molten feed wax in a container; (b) solidifying the feed wax by cooling; (c) increasing the tem- perature of the feed wax to a temperature at which a first frac- tion of the feed wax melts, said first fraction having a con- gealing point which is lower than the congealing point of the feed wax; (d) recovering the first fraction of the feed wax; (e) increasing the temperature of the remaining feed wax to a tem- perature at which a further fraction of the feed wax melts; and (f) recovering the further fraction of the feed wax. The feed wax comprises at least 75 wt.-% of linear alkanes and each re- covered fraction comprises at least 19 wt.-% of the feed wax.
摘要(中):
一种从进料蜡获得蜡馏分的方法,其过程包括:(a)在容器中提供熔融进料蜡; (b)通过冷却固化进料蜡; (c)将进料蜡的温度升高到进料蜡的第一馏分熔化的温度,所述第一馏分具有低于进料蜡凝结点的接头点; (d)回收进料蜡的第一部分; (e)将剩余的进料蜡的温度升高到另外一部分进料蜡熔化的温度; 和(f)回收进料蜡的另外部分。 进料蜡包含至少75重量%的直链烷烃,每个重新包覆的馏分包含至少19重量%的进料蜡。
