Abstrakt: The efficiency of dewaxing of wide and narrow distillation raffinates using different mixed solvents: acetone and methyl–tert–butyl ether (MTBE), acetone and toluene, methyl ethyl ketone (MEK) and toluene, is compared. Decreasing the cutpoints from 100–140 to 50–70°C increases the filtration rate by 2 and more times and the yield of dewaxed lube oil by 2.5–5% as a function of the solvent used.
