...help break up the complex hydrocarbon compounds and recombine them into more usable form. Catalytic cracking, with various catalysts and conditions of use, can be controlled to a far greater degree than the older thermal cracking, in which reactions are produced by high temperatures and pressure. But coke (carbon) is by the nature of the reaction deposited on the catalyst, affecting the speed and control of the process, and hitherto it has been necessary to call halts while the catalyst was burned off or a switchover was made to fresh catalyst...
...vapors and the "fluid" catalyst are forced under 10-lb. pressure through tiny holes into a reaction chamber at a temperature of around 800-975° F. In scant seconds the oil is cracked and the mixture-vapors, gases and carbon-coated catalyst-moves up through cyclone separators where the powder is dropped into a spent catalyst chamber. From there it flows into a regeneration chamber where a stream of air burns off the carbon at a temperature of 1,000-1,150° F. The powder, still moving, is cleaned of remaining gases in more cyclone separators...
...impact switch has been developed by Walter Kidde & Co. which automatically releases several pounds of compressed carbon dioxide gas into the engine compartment of a plane if it crashes, thus helps to put out fire even if the pilot is incapacitated. An adjustable trigger device prevents release of the gas by twists in flying, bumps in landing...
...full cry, dropped her bellow to a mutter, stopped, turned around again. Smoke plumed from one of her engine nacelles. But fire there meant less danger than it had meant in older ships. In each fireproof engine housing were 16 thermostatic fire warnings and an extinguishing system to put carbon dioxide just where it was needed. The blaze, from a backfire, died...
Some time next week the first synthetic-rubber plant in Rubber Czar William Jeffers' 1,000,000-ton program will actually start turning out butadiene-the strategic chemical that forms the basis of Buna-S tire rubber. The plant: Union Carbide & Carbon's 80,000-ton unit at Institute, W. Va., which will make rubber from grain alcohol...
