Definitions

  • Benefits of the present invention are obtained by dissolving carbon dioxide into the liquid strong acid catalyst. Maximum benefits are obtained when the strong acid is saturated with carbon dioxide at the alkylation reaction conditions employed. In order to encourage solution of carbon dioxide in strong acid, it is usually desirable to employ an excess of carbon dioxide. In treating the strong acid, weight ratios of carbon dioxide to strong acid of about 0.1/100 and higher may be employed. Preferably weight ratios of carbon dioxide to strong acid of at least 5/100 are employed. Great excesses of carbon dioxide to strong acid in the acid treatment are not necessary,
  • Contact time of carbon dioxide with strong acid being treated need only be sufficient for solution of the desired amount of carbon dioxideint'o the strong acid. Contact times of from a few seconds to 24 hours and longer may be employed. Necessary contact time will be shorter with better mixing and more intimate contact of carbon dioxide with the strong acid. Preferred contact times for any particular acid treating system may be easily established by observing the rate of solution of carbon dioxide into the strong acid under the conditions of pressure, temperature and degree of mixing present in the particular system under consideration.
  • alkylation reactions contemplated in the present invention are carried out in the liquid phase.
  • the reactants need not be normally liquid hydrocarbons.
  • Alkylation reaction conditions can vary in temperature from below zero to about 100F., and can be carried out at pressures of from atmospheric to 1000 psig and higher.
  • olefin space velocities of from about 0.01 to about volumes olefin/hour/volume of catalyst may be employed.
  • Molar ratios of isoparaffin hydrocarbonto alkylati'ng agent of from about 1:1 to about 50:1 and higher may be emloyed.
  • substantial molar excess of isoparaffin to olefin is maintained in an alkylation reaction, with molar ratios of isoparaffin to olefin of'from about 5:1 to about 20:1 being particularly preferred.
