Abstract

Petroleum fractions or similar hydrocarbonaceous materials are converted into liquid, highly (over 95%.) aromatic products and highly olefinic gases, when cracked in packed tubes at 630‐650°, at slightly super‐atmospheric pressure and a space velocity of 0·05‐0·5. Metallic packing, especially copper, is most efficient. The greater part of the sulphur, nitrogen and oxygen in the charging stock is converted into hydrogen sulphide, ammonia and water. The hydrocarbons are cracked to very small unsaturated molecules, from which the cyclic substances arc formed by re‐synthesis. The central position of butadiene in this sequence of reactions has been established. The influence of operational factors on the process, its thermochemistry and the composition of the product is discussed.
