ABSTRACT:
Lubricant components of high viscosity index are selectively separated from hydrocarbon base stocks by a selective sorption process using an intermediate pore size zeolite such as ZSM-5 as the sorbent. The process is of particular utility with synthetic lubricant stocks produced by the oligomerization of light olefins. The sorbed components may be desorbed from the zeolite to recover a high VI lubricant.
