Process. Refined motor spirit. Other refined light oils. Heavy oils.
Million gallons. Million gallons. Million gallons.
Hydrogenation … … 35.0 — —
High temperature carbonisation … … 53.5 14.0 91.0*
Low temperature carbonisation … … 1.0 — 6.0*
* Some proportion of these heavy oils (creosote and low temperature tar oils) are hydrogenated to obtain the quantity of motor spirit shown.
