Tests of 15 plants have been made by the Department of Scientific and Industrial Research under the published conditions for testing of plants for the low temperature carbonization of coal. These tests are concerned only with the performance of the plants during the period of test and with the technincal aspects of the processes involved. Reports upon these tests are intended to place accurate technical data in the hands of those interested, and no attempt is made to pronounce on the commercial possibilities of the plants concerned. Experimental work on the production of oil from coal by low temperature carbonization and other methods, such as hydrogenation and synthesis from mixtures of carbon monoxide and oxygen, has also been carried out by the Fuel Research Station as part of its normal programme. I am sending the hon. Member a copy of the latest published report of the Fuel Research Board, in which reference is made to this work, and also a copy of the conditions under which tests of low temperature carbonization plants are carried out.
asked the Secretary for Mines whether he can now state the names of the members of the sub-committee of the Committee of Imperial Defence which has been constituted to examine the various processes for the production of oil from coal having regard to the necessity of security of oil supplies in emergency.
