His description of the importance of fundamental chemistry tied directly to engineering practice was a challenging revelation to me. I was intrigued by the UOP culture and by what seemed a unique approach to rapid commercial exploitation of research results.

That process removed tetraethyl lead from gasoline, providing high-octane fuel (which allowed for high-performance, high-compression engines) and a source of a romatics for the plastics industry (which eliminated the need for coal tar chemistry)

They came to the United States in 1930 when Haensel's father accepted a teaching position at Northwestern University. Haensel entered Northwestern University in 1931 and received a bachelor of science degree in general engineering in 1935.

He was a member of the National Academy of Sciences and the National Academy of Engineering and was recognized with awards that included the National Medal of Science, the Perkin Medal, the first National Academy of Sciences Award for Chemistry in Service to Society, the Professional Progress Award (American Institute of Chemical Engineers) , the Draper Prize, and the Chancellor's Outstanding Teacher Award (University of Massachusetts)

Another octane booster was tetraethyl lead, which was used heavily until the 1970s, when it was phased out of gasoline because of the toxicity of the lead compounds in auto exhaust. It was not generally understood that the clay catalysts used by Eugène Houdry were in reality solid acids and that the chemistry of catalytic isomerization and catalytic cracking of straight hydrocarbons was thus akin to that of the liquidacid catalyzed alkylation invented by Ipatieff and Pines.

From page 90... ...
Hydrogen adsorption indicates that more than 50 percent of the platinum atoms are surface atoms. Even more important was his proposal that platinum on alumina was a dual-functional catalyst, ideally suited to the catalytic reforming chemistry.

From page 91... ...
This created the base for the modern plastics industry, which previously relied on the processing of coal tar, a very environmentally unfriendly process. Through catalytic reforming chemistry, more than 200 billion pounds of aromatic hydrocarbons are produced each year.

World consumption of oil was 66 million barrels per day, of which the United States accounts for roughly one-fourth. Vladimir Haensel Returns to Teaching After serving as vice president for science and technology at UOP, Haensel joined the faculty at the University of Massachusetts, Amherst, in 1980 as professor of chemical engineering.

From page 93... ...
Haensel served as a board member of the Petroleum Research Fund, 1979–1982; chair of the US-USSR Technology Exchange in Chemical Catalysis, 1976–1979; US State Department Representative to the International Scientific Forum in Hamburg, Germany, 1980; chair of the advisory committee, Industrial Science and Technology Innovation of the National Science Foundation, 1982–1985; and a member of the board of directors of Heico Corporation. He authored more than 120 scientific and technical papers, and was granted over 145 US patents and 450 foreign patents.
