Title: Zhenping Cai: Innovator in Biodiesel Production

Introduction

Zhenping Cai is a notable inventor based in Guangzhou, China. He has made significant contributions to the field of biodiesel production, holding a total of 4 patents. His innovative methods focus on the efficient use of waste fats, oils, and greases to produce sustainable energy sources.

Latest Patents

Cai's latest patents include a method for pretreating waste fat, oil, and grease (FOG) to co-produce first-generation biodiesel. This method involves several steps: first, feeding waste FOG, a liquid acid catalyst, and methanol into a pre-esterification reactor. This process results in a pre-esterification mixed liquid, which is then filtered to remove waste residues. The filtrate is separated into an organic phase and an aqueous phase. The organic phase undergoes further separation to yield a pre-esterification product and crude methanol. The aqueous phase is processed to recover the liquid acid catalyst and crude methanol. Finally, the pre-esterification product is refined to obtain a first-generation biodiesel product.

Another significant patent is a coupling process for producing biodiesel from waste FOG. This process includes removing solid impurities from the waste FOG, mixing it with alcohol and a liquid acid catalyst to create a pre-esterified mixture. The mixture is then treated with water to separate an aqueous phase, which helps remove metal ions, resulting in an esterification product. This product is further processed to obtain an oil phase, which is then refined to produce biodiesel.
