...poet of this book's title is D. H. Lawrence. The painters are Knud Merrild and Kai Götzsche, two strapping Danish immigrants who met Lawrence in Taos, N. M. in 1922, lived that winter with him and his wife, Frieda, in a crude ranch shack which they rented to escape Mabel Dodge (Luhan). Among the flood of memoirs-mostly by women-which have appeared since Lawrence's death in 1930, this one comes nearest to giving an objective picture of Lawrence...
Most present oil refining is done by thermal cracking-breaking crude oil's heavy molecules into lighter components by great pressure and heat. This process yields only 44% gasoline (the money-making product), leaves refiners with a great bulk of fuel oil and other by-products to dispose of. Phillips Petroleum Co. has lately found a way to convert some of these by-products into gasoline-through polymerization, which compresses wasted gaseous fractions of crude oil into the heavier molecules of gasoline...
Inventor Houdry has an entirely new approach. In his arduous attempts to make gasoline from lignite, he happened on a catalyst (an agent that accelerates chemical action without becoming part of the product it activates) which converted crude to gasoline without the great pressure or heat required in thermal cracking. Unable to get backing in France, he found...
...March 31, 1937, at Sun Oil's Marcus Hook plant hard by the Delaware River, engineers charged Houdry Unit 11-4 with 15,000 barrels of sloppy residuum after Sun's thermal cracking refiners had squeezed every drop of gasoline they could from the crude. Up went the heat to 900°. Pressure was applied. And as still men and panel men anxiously watched the gauges, the vaporized residuum was forced through the macaroni-shaped catalyst of silica and alumina. When 11-4 had done its work, yield sheets showed that the waste oil had given...
...result with ordinary gas to improve the octane rating. If Houdry refining becomes general, it may: 1) reduce the need for the tetraethyl lead which now makes most gasoline satisfactory in modern high-compression engines; 2) conserve U. S. oil reserves by yielding more gasoline per barrel of crude; 3) help stabilize prices by stabilizing stocks, now badly unbalanced because gasoline and fuel oil must be produced simultaneously though one is most used in summer, the other in winter...
