Process studies of the solvent distribution process for coolant reclamation were centered on filtration and distillation tests. Based on tests carried out using a leaf filter, filtration rates of 35 to 50 gal/sq ft/hr may be obtained. The filter cake retained 40 to 50 wt% solvent, indicating a drying process to recover solvent must follow the filtration process. The micro-pilot plant was operated to test the 2-in. diameter distillation column packed with 3 x 2 in. wire cartridges. Twenty-one catalysts were tested for hydrocracking activity toward reclaimed high boiler. Copper, platinum, palladium, chromium, and molybdenum on acidic supports proved to be the best catalysts for hydrocracking reclaimed high boiler. Product yields varied from 33 to 88%; coke yields from 1.8 to 4.8%, and gas yields from 0.4 to 4.5%. Products from the best catalysts varied in physical appearance from brown oils to yellow oil- crystalline mixtures, a marked change from the solid, glass-Iike, darkbrown feed materials. The products had lower carbon-tohydrogen ratios, lower molecular weights, lower viscosities, and higher decomposition temperatures than high boiler or reclaimed high boiler. Pyrolytic capsule fouling test data on product from the solvent distribution method (spent coolantpetroleum solvent) showed a 98% decrease in film formation. Spent coolant gave an average of 63.4 mg; reclaimed spent coolant gave an average of l mg. (auth)
