Process for catalytic dimerization of isobutene |
摘要 |
Disclosed is a process for carrying out the selective dimerization of isobutene in order to produce alpha- and beta-di-isobutene dimers, according to which process an isobutene stream is brought into contact, under dimerization conditions, with a solid silica gel/alumina catalyst which is amorphous when analysed by X ray diffraction, displays a molar ratio of SiO<6>/Al<6>O<7> comprised within the range of from 30:1 to 500:1, has a surface-area comprised within the range of from 500 to 1000 m<2>/g, a porosity of from 0.3 to 0.6 ml/g and an average pore diameter of approximately 10 ANGSTROM ( ANGSTROM ngstrom), and is free from pores with a larger diameter than 30 ANGSTROM . |
