With a remarkable portfolio of 18 patents, he has significantly contributed to advancements in the methods for producing fatty acid esters and improving the efficiency of crude oil and fat pretreatment processes.

Latest Patents

Among his latest innovations, Rainer Frische has developed a sophisticated method for the production of fatty acid esters. This method revolves around utilizing primary and/or secondary alcohols from raw, unpurified oils or fats laden with free fatty acids and slimy substances, as well as waste oils from the food industry. The process employs acidic catalytic esterification to manage the adverse effects of slimy substances that form emulsions. By incorporating a water-free primary or secondary alcohol and a highly acidic hygroscopic catalyst, the reaction creates a product that is subsequently rinsed with glycol from prior alkaline transesterification.

Another notable patent pertains to the pretreatment of crude oils and raw fats intended for fatty acid ester production. This method addresses the contamination of oils or fats by slimy substances, utilizing a specific mixture comprising alcohol and concentrated acid. The treated product is rinsed with an alkaline glycerol phase, allowing for the separation of a heavy phase of neutral oil that is freed from free fatty acids.
