Adsorbing Gel. One of the most efficient adsorbent materials known, silica gel was first produced commercially (for use in gas masks) in World War I. It also has industrial uses as a dehydrator and catalyst. Made by drying a gelatinous form of silicon dioxide, silica gel looks like crushed quartz, is riddled with invisible pores so numerous that a cubic inch has more than 50,000 square feet of interior surface. By adsorption (sticking of moisture to the surface), silica gel can hold half its own weight in water without swelling, caking or developing a visible sweat...
Young Man from Yale. Baker's letter was the catalyst that changed the limping, directionless Council into the powerful educational instrument it is today. To Cleveland came the young instructor from Yale-Brooks Emeny, the Council's present director. Graduated from Princeton in 1924, Emeny selected diplomacy as a career, studied abroad for three years as a Carnegie Fellow in international...
...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...
Asked if the Axis might not develop the same process, Standard's Gallagher hitched his shoulder a little higher, murmured it was not likely: key to the process is a synthetic and costly catalyst which is a commercial as well as a war secret...
...catalyst is an innocent chemical bystander whose mere presence on the scene promotes or hastens an activity in which the catalyst itself is not involved. Common example: vegetable oils are solidified with hydrogen, in the presence of nickel as a catalyst, to make kitchen shortening...
