Alkylation of isobutane with butylenes on zeolitic catalysts
In the liquid-phase alkylation of isobutane with butylenes in the presence of a zeolitic catalyst containing calcium and rare-earth cations, the product that is obtained consists mainly of a mixture of saturated hydrocarbons and is similar in composition to the product from sulfuric acid alkylation.
The greatest yield of alkylate is observed when the reaction is conducted in the liquid phase at 100°C.
Gas-phase alkylation of isobutane with butylenes gives a lower conversion and leads to the formation of a product with low content of trimethylpentanes.
