       Use of various technically available gases and mixtures is examined practically and theoretically.  Gas mixtures containing CO and H₂ in approximately the ratio of 1:2 may be produced by mixing coke-oven gas with generator gas or with water gas (Mischgas), which may be produced simultaneously in the coke oven by the direct gasification of coal or by the interaction of CH₄ with steam and/or CO₂ or O₂, etc.  Heat balances have been drawn up for the more important of these processes.  The influence of temperature and pressure upon equilibrium and reaction rate has been determined for the cracking of CH₄ by steam over Ni-Al catalyst at 800° per 1 atm. or at 600° per 0.1 atm. with a contact time of less than 1 sec.  The effects of temperature and coke activity upon the conversion of coke-oven gas with steam over coke have been determined.  A scheme for using coke-oven gas thus regenerated is proposed.
