The production of automitive fuels from domestic sources can be produced according to different schemes for direct liquefaction. Experimental studies have been made concerning the problems connected with high pressure liquefaction, focused on composition and production of the contemplated recirculated solvent for dissolution. Special importance has been given to a fundamental study for the choice of raw materials, especially peat. Deactivation of catalysts for hydrotreatment has been initiated and analytical methods for the characterization of products have also been further developed. (G.B.).
