Reviews the literature on the gasification of coal with steam and O₂ under pressure and describes the plant and its operation in detail. Gives flowsheets. In general, it was found that lean, hard coal could be gasified under pressure satisfactorily, while gas-flame coals usually required pretreatment to reduce the caking properties. The proportion of CH₄ formed on gasification increased with increasing pressure and decreases with increasing temperature. By gasification at 20 atm. it is possible to produce a gas with calorific value of 5,000 kcal. per N m.³ In actual practice the theoretical value is not obtained. However, the more reactive the fuel gasified, the nearer does the gas approach the ideal. Operating data, analyses and costs are tabulated. Describes operation of the A.-G. Sachsische Werke at Böhlen in detail, and covers the experiment to produce synthesis gas from hard coal in less detail.
