Abstract

A catalyst for reforming hydrocarbons comprises a chromia-alumina catalyst containing a minor proportion of bismuth or a bismuth compound and may be promoted with an alkali metal oxide. The catalyst preferably contains 5 to 25% chromia, 0.1 to 5% bismuth oxide and 0.1 to 5% potassium oxide, the balance being alumina. In an example, 160 g. of 4-8 mesh B.S.S. granulated alumina was roasted for 2 hours at 550 DEG C. and impregnated with a solution of 23 g. chromium trioxide, 4 g. potassium nitrate and 3.9 g. bismuth nitrate in 40 ml. of distilled water and 40 ml. of conc. nitric acid. The solution was wholly absorbed and the catalyst dried at 120 DEG C. for 15 hours and roasted at 550 DEG C. for two hours. The first Provisional Specification also refers to the use of chromia-alumina catalysts containing a minor proportion of bismuth, tin or antimony and a minor proportion of potassium, caesium or nibidium. Specification 820,403, [Group IV (b)], is referred to.ALSO:A feedstock comprising non-aromatic hydrocarbons is reformed at 450-580 DEG C. and not more than 50 p.s.i.g. with a chromia-alumina catalyst containing a minor proportion of bismuth or compound thereof in the absence of added hydrogen whether extraneous or recycled. The feedstock should boil within the gasoline or naphtha range and preferably comprises C5-C7 hydrocarbons, such as a straight-run distillate or may be the whole or part of a catalytic reformate particularly a lower-boiling fraction or a raffinate from a solvent extraction of a reformate. The catalyst preferably comprises 5-25% chromia, 0.1 to 5% bismuth oxide, and 0.1 to 5% alkali metal oxide (e.g. potassia). Space velocities of 0.1 to 1 vol./vol./hr. are used. In a typical example a low-boiling fraction of a platinum reformate (end point 108 DEG C., research octane number 76.1) was treated at 530 DEG C. atmospheric pressure and 0.2 vol./vol./hr. with (a) 10% chromia on alunina with 1% bismuth oxide to give 65.8% of a product of octane number 101.1; (b) the same catalyst with 1% potassium oxide to give 66.6% of a product octane number 102.8. The first Provisional Specification also refers to the use of chromia-alumina catalysts containing a minor proportion of bismuth, tin or antimony and a minor proportion of potassium, rubidium or caesium. Specification 820,403 also is referred to.
