(1) Coal Carbonization, High and Low Temperature: a Treatise on the Principles and Processes of Manufacturing Coke and Semi-Coke (2) Oil and Retortable Materials: a Handbook on the Utilisation of Coal, Torbanite, Cannel and Oil Shale

Abstract

THESE two books exemplify the activity which JL is now being displayed in following up the possibilities of the carbonisation process in various directions, and the results of operating by methods removed in varying degrees from the standards of normal coke-oven and gas-works practice, including the treatment of raw materials other than ordinary coal. In the first and longer work, the stress is laid upon carbonisation as a means of producing different varieties of solid fuel which can be grouped under the name of coke, while Mr. Halse's smaller book is inspired by the purpose of discussing what may be done to increase the production of liquid fuel in Great Britain by the utilisation of such materials as torbanite, cannel, and oil shale.
