Abstract
A method for converting a diol in solution to an olefin fraction, the method comprising: (i) reacting a diol of the formula HO—R—OH in solution with a carbonyl-containing molecule of the formula: in the presence of an acid catalyst to result in a dioxolane molecule of the formula: wherein R is a hydrocarbon linker containing 1-12 carbon atoms, and R1 and R2 are independently selected from hydrogen atom and hydrocarbon groups containing 1-12 carbon atoms, wherein R1 and R2 optionally interconnect; (ii) removing the dioxolane molecule from the solution by phase separation; and (iii) contacting the dioxolane molecule with a metal-loaded zeolite at a temperature of 100-500° C. to convert the dioxolane molecule to an olefin fraction.
