Abstract: Methods and system for obtaining long chain carbons that generally include forming a conversion mixture of an alcohol and a base, adding the conversion mixture to oil (such as petroleum based oil, crude oil, used oil, used motor oil, and new motor oil) to form a reaction mixture, adding a high nitrate compound the reaction mixture, and separating out the long chain carbons for use as an input by other processing such as pharmaceutical and/or additional petro-chemical processing. Additional cooling and/or filtering processes may be utilized to complete and/or optimize oil conversion.
