Engelhard Industries, Iselin


The four men combined efforts for the Engelhard Corporation of Iselin, N.J., in the invention and development of a three-way automotive catalyst that is especially effective in reducing hydrocarbon emissions, a major cause of air pollution. The team's invention of a new, robust high performance pollution-control (Pd) catalyst has allowed auto manufacturers to locate the catalyst very close to the engine manifold - as opposed to the previous method near the exhaust - and thus greatly reduce the time for the catalyst to reach its operating temperature. In addition, the catalyst has been engineered at a molecular and microscopic scale to provide the highest known conversion of hydrocarbons while converting high levels of carbon monoxide and nitrogen oxides.

Dettling holds more than 30 patents, many of which represent keystones in emission control technology. His creativity permeates a broad range of Engelhard's products that are being sold throughout the world and at the base of a profitable and growing business segment for the company.

C.Z. Wan's research has provided a fundamental understanding of the three-way catalyst components as they relate to the application. He holds 13 patents, several of which have contributed to the improvements seen in many of the company's high technology TWC catalysts.

Y.K. Lui has contributed to the development and improvement of automotive and carbon supported catalysts in support of the company's environmental and chemical catalyst business groups. He holds six patents.

Zhicheng Hu holds two patents. As a junior member of the Engelhard R&D staff, his creativity in designing elegant solutions to complex emission/catalyst problems is gaining notice.
