HYDROGENATED TARS AS PROBABLE SOURCES OF T-5 FUEL.
Abstract
The two-part study of Lozovoy and associates reported does not directly refer to the production of T-5 fuel. In fact, the purpose of the study, as stated, was to formulate a simplified method of producing highly aromatic gasoline from hydrogenated coals and tars by changing the existing four-stage hydrogenation process to a single-stage process. With this end, the activity of catalysts based on acid-activated native clay -- 'Askenit' -- with oxides and sulfides of heavy metals, such as Cr, Zn, W, Mo, V, and Ni, was studied. A catalyst containing W, Cr, Zn, S, and F on activated 'Askenit' was found to produce satisfactory results in the hydrogenation of unrefined coal distillates under 300-atm pressure at 510C. Some decline in the activity of the catalyst after 97 hours of testing was noted. (1) The second part of the study describes efforts to develop similar catalysts which would be stable under hydrogenation temperature and pressure conditions. A catalyst based on activated 'Askanit' and containing oxides and sulfides of Cr, Zn, and W was found to be adequate at 501-505C under 600-atm pressure.
