Filed:

Jul 27, 2018

Appl. No.:

16/047009

Inventors:

Michael P. Doyle - Carmel CA, US
Glenn Richards - Bakersfield CA, US

International Classification:

C10G 31/10
C10G 53/02

Abstract:

A Process for the purification of renewable oils. The process may also be applied to petroleum oils such as used motor oil and the like. The process involves centrifuging the renewable oil in a centrifugal device producing a minimum of 7000 Gs, then contacting the oil with a mixture containing water, a straight chain hydro-treated ester compound, and a phosphate derivative at a minimum temperature of 100 C. for 10 minutes, then raising temperature to approximately between 120 C. and 130 C. to complete reaction. The mixture is then again centrifuged in a centrifugal device producing a minimum of 7000 Gs.

Abstract:

Animal and seed based triglycerides are oils used in cosmetics, pharmaceuticals, animal feed, energy generation, etc. These triglycerides or glycerol esters are a mixture of triglycerides and free fatty esters (FFA) along with unsaponifiables and gums (MIU). FFA may range from very low, 1% or less, to more than 40% in some rendered animal oils. Corn oil from the wet or dry process of ethanol production may have from 7 to 15% FFA. The varying amount of FFA presents numerous process issues for downstream users of these oils especially in the production of biodiesel, fatty acid methyl ester (FAME). FFA about 1 or 2% requires esterification as well as transesterification for the production of FAME. What is needed is a method to perform Glycerolysis. This disclosure describes an improved catalyst system as well as process equipment and operating conditions to allow economical commercialization of Glycerolysis.
