Latest Patents

Ralf Wehn holds a patent for a process titled "Reprocessing of Contaminated Oils." This patent describes a method for reprocessing used crankcase oil from automobile engines through thermal treatment, such as visbreaking. The process involves the use of other hydrocarbon feedstocks, followed by fractional distillation to recover various fractions, including gasoline, carboxylic acid, gas oil containing chlorinated hydrocarbons, and high boiling bottoms. The gas oil fraction undergoes catalytic hydrocracking, which effectively destroys chlorinated hydrocarbons. The resulting hydrocracked oils are free from chlorine compounds and other contaminants after the separation of hydrogen chloride.
