A Coke Process Also

A Coke Process Also.

The Billingham-on-Tees undertaking is based on the process of hydrogenation. Another well-known coal-cracking process is low temperature carbonisation. Both are highly technical and are still developing. To the layman. a conspicuous point of differentiation is that the hydrogenation process of coal-cracking has for its main product the petrol referred to above; while the carbonisation process has for its main product a smokeless coke, with oil and petrol as secondary products. Experts have pointed out that if the smokeless coke of carbonisation could capture practically the whole household fuel consumption of Britain (for which it is well suited) then the secondary product oils might be produced in sufficient quantity to make Britain independent of petrol and oil imports. Instead of building on that “if,” Imperial Chemical Industries rely on the petrol process—that is, on hydrogenation. At the same time, the smokeless coke of carbonisation, if burned in grates, would mean a less polluted atmosphere.
