WWI Benzole extraction plants were installed alongside the coke ovens at collieries, gasworks, steelworks and tar distilleries for the manufacture of T.N.T. and other explosives. After the war a market developed for benzole blended with petrol as a motor spirit. The National Benzole Co was formed as a co-operative selling organisation by the benzole producers; the company obtained its petrol requirements from Anglo-Persian Oil Co.
