TH23174B - Biodegradable high-performance hydrocarbon oil? - Google Patents

Abstract

This document reveals a novel biodegradable high-performance hydrocarbon oil used as a lubricant in engine oils and industrial compounds, and the process for its production. A paraffin-based wax, specifically Fischer-Tropz wax, is subjected to a dual-acting catalyst for hydroisomerization and hydrocracking at 700°F+, with a transformation degree ranging from approximately 20 to 50% by weight (typically 25-40% by weight), sufficient to form a crude distillate. This crude distillate is a C5-1050°F+ fraction containing 700°F+ branched methyl isoparaffins with approximately 6.0 to 7.5 carbon atoms per 100 carbon atoms in the methyl paraffin molecule. The crude distillate is then subjected to atmospheric distillation to produce a tail distillate with an initial boiling point between approximately 650°F and 750°F, which is then further processed by dewax solvent. The dewaxed oil is then fractionated under high vacuum conditions to produce biodegradable high-performance hydrocarbon oil.
