FIELD: chemistry.
SUBSTANCE: invention relates to isomerisation catalysts. Described is a catalyst for isomerisation of C8-aromatic compounds, containing: a) 1-90 wt % MTW-zeolite; b) 10-99 wt % binding material which is gamma aluminium oxide, where the gamma aluminium oxide is obtained from aluminium oxide in form of boehmite;where a) and b) form an initial base, c) 0.1-2 wt % noble metal in terms of the initial base; and d) at least one alkali metal, where total content of the alkali metal in the catalyst is at least 100 pts. wt in terms of the initial base; e) where the catalyst has pore volume distribution and at least 70% of the pore volume of the catalyst is defined by pores having diametre of greater than 100 Å.
EFFECT: isomerisation catalyst enables to carry out isomerisation with minimisation of loss of C8-rings.
