Review dealing with new processes for complete gasification and oleofication of coal. Synthesis of the Radische process (German Patents 293,787, 295,202, 295,203), transforms water gas by means of metal-oxide catalysts into oily and aqueous products. One example of this process if the MeOH synthesis (ZnO catalysts, temperature 200°-600°, 50-150 atm. pressure); iron carbonyl Fe (CO)5, antiknock (motalin), is a byproduct. Franz Fischer prepares synthol by catalysis at 400°-450° up to 150 atm. pressure with an alkali-Fe mixture and obtains a motor fuel from the water-insoluble fraction. This synthesis is possible also (see abs. 1021) without high pressure of a Fe-Zn oxide catalyst is used (or Co-Cr oxide) and yields higher CH4 homologs at temperatures around 270°; metal carbides are intermediary products (at higher temperatures CH4 is the only product formed). Yield of useful hydrocarbons is about 55%. The product gasol, is mainly C2H6, C3H8, and C4H10, little unsaturated, nonresinifying, clear, and not sensitive to light. Refining appears unnecessary for use as motor fuel, d15=0.6718, distillation 75.3% up to 100°, 96.4% up to 180°; the rest is kerosinelike, d20=0.7804. Occasionally solid paraffin, melting at 61°, was formed. The importance of the absence of high-pressure installations for this synthesis is emphasized. BANGERT, F. See abs. 977. BANGERT, W. M.
