摘要
Abstract
Using waste oils as raw materials,the composition,origin and application of high-boiling fractions in the hydrorefined oil were investigated by GC,GC-MS,coking plate test,pressurized differential scanning calorimetry,high-frequency reciprocating rig,and ultrasonic dispersion.The experimental results show that the high-boiling fractions in hydrorefined oils are mainly derived from non-glyceride unsaponifiables in waste oils;it is difficult for hydrorefining catalysts to effectively convert high-boiling fractions into diesel fractions;high-boiling fractions can be prepared into high value-added bio-based lube base oils through hydroisomerization,realizing the efficient utilization of the full distillate of hydrorefined waste oils.关键词
