Abstract
A method is patented for producing n-hexane and hexane concentrates by dearomatization of benzene fractions when content S is less than 20 ptm and a certain quantity of aromatic hydrocarbons and unsaturated hydrocarbons. To remove these hydrocarbons from the initial raw material (benzene fractions, reformed benzene fractions, hexane concentrates, raffinates from extraction of aromatic hydrocarbons, alkane concentrates from adsorption of n-alkanes in molecular sieves) it is subjected to hydrogenation of H/sub 2/ or H/sub 2/-containing gases with heterogeneous catalysts, which have hydrogenation, dehydrogenation activity and which contain metals of the VIII group of the periodic table, such as platinum or platinum containing bimetallic catalysts. Hydrogenation is conducted in one of several stages at temperature 50-400 /sup 0/, partial pressure of H/sub 2/ 100-20,000 kPa, volumetric speed of 0.1-15 hours/sup -1/ and quantity of H/sub 2/ of 1.5-150 times the predominant stoichiometric quantity. Hydrogenation can be done in fresh or repeatedly covered catalysts.
