Title: Innovations by Inventor Jen-Ray Chang
Introduction
Jen-Ray Chang is a notable inventor based in Minhsiung, Taiwan. He has made significant contributions to the field of catalysis and construction materials, holding a total of 4 patents. His work focuses on developing innovative solutions that enhance production processes and material properties.
Latest Patents
One of his latest patents involves the creation of homogeneous catalysts for biodiesel production. These non-basic and non-acidic organo-metallic compounds can catalyze the transesterification of oils and fats with high free fatty acid content into biodiesel. The catalysts, represented by the formula M(OCH), where M includes various metals, allow for continuous biodiesel production without the complications associated with traditional methods. This innovation results in high purity biodiesel without the need for acid-base neutralization, water wash, filtration, or solid disposal steps.
Another significant patent by Chang is a method for producing improved rubberized concrete using waste rubber tires. This process involves the partial oxidation of crumb rubber derived from hazardous waste tires, yielding surface-treated crumb rubber. This treated rubber is then used as a blending stock for rubberized concrete, which exhibits substantially improved mechanical strength compared to conventional rubberized concrete. The enhanced interaction between the hydrophilic surfaces of the rubber and cement matrix leads to a more versatile and effective construction material.
