714. ---------------. [DOLCH, P.] [Water-Gas Generation From Coal and Coke.] Gas- u. Wasserfach, vol. 75, 1932, p. 974; Chem. Abs., vol. 27, 1933, p. 827. Reply to abs. 1412 and 2436. The attainment of the water-gas equilibrium depends more on the reactivity of the carbonization product than on the ash content. In general the degree attainment of this equilibrium parallels the reactivity of various cokes with respect to water vapor as given by Bunte (abs. 407). Experiments at 800° with a beechwood charcoal containing 2.3% ash indicated substantial attainment of the water-gas equilibrium as did experiments with a coke containing 5.3% ash. Both charcoal and coke were prepared by carbonizing the wood or coal at 1,000°. |
