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.
