Introduction

Mark Wilkins is an accomplished inventor based in Stillwater, OK (US). He has made significant contributions to the field of ethanol production, particularly through innovative methods that utilize solid citrus processing waste. With a total of 2 patents, his work focuses on enhancing the efficiency and sustainability of ethanol production.

Latest Patents

Wilkins' latest patents include a method for producing ethanol from solid citrus waste. This method involves reducing the concentration of limonene in citrus waste to facilitate fermentation. In one embodiment, the ground solid citrus waste is partially hydrolyzed and pasteurized using a jet cooker, followed by injection into a flash tank to remove limonene. The treated citrus waste is then cooled, hydrolyzed with enzymes, and fermented to produce ethanol. The remaining solids and liquids can be further processed to yield valuable byproducts, such as cattle feed and additional ethanol.

Another notable patent is a method of pretreating citrus waste. This method aims to break down the cell structure, pasteurize the solids, and remove inhibitory peel oil components like limonene. The process includes reducing the particle size of the citrus waste, preheating it through indirect heating, and then conveying it to a main reactor for further treatment. The resulting pasteurized citrus waste solids can be saccharified with enzymes and fermented to produce ethanol or other products.
