Show Seek New Methods to Conserve Coal Kxperts in all parts of the world are tackling the problem of how lo use coal to the best advantage. Professor Bergius of Heidelberg has reduced -coal to a' paste and combined It with hydrogen at a very high temperature tem-perature and pressure. The resulting fluid has all the properties of crude petroleum and can be treated In the same "way to produce petrol and other oils. Another scientist reduces coal to a gaseous form and then liquefies the gases. He has produced methanol, which seems to have all the properties of wood alcohol ; synthol, equivalent to a high-grade petrol ; and a substitute substi-tute for benzine. General Patart, a Frenchman, has been experimenting with coal-produced synthetic alcohol, which shows n saving sav-ing of 15 per cent in calories over petrol. The temperature of the radiator radi-ator in which it Is used was considerably consid-erably lower than In cars using petrol. |
