    Abstract: The hydrogenation of cyclic hydrocarbons containing olefinic double bonds is effected in the vapour phase at elevated temperature and atmospheric pressure in the presence of a large excess of hydrogen and a hydrogenation catalyst deposited on a macroporous carrier preferably having a pore size of not less than 1000 . Suitable catalysts contain 1-10% of platinum or palladium by weight of the carrier or a mixture of 10-20% of nickel, 1-10% of copper and 0.5-5% of manganese. The carrier may be granulated Italian pumice, kieselguhr, precipitated or muffle-heated silica or macroporous activated carbon. Suitable temperatures are 120-300 DEG C. and the initial material may be mixed with 10-50 times its volume of hydrogen. Aromatic rings are unaffected. The hydrogenation of cyclo-octatetraene, cyclodecapentaene, cyclododecahexaene, vinylcyclo-octatetraene, cyclododecatriene and phenylbutadiene is referred to.
