Abstract

Process for isomerizing 1-butene to 2-butene by contacting 1-butene, at a temperature from 50 to 140.degree. C, in the presence of hydrogen, with an isomerization catalyst containing a noble metal from group VIII of the periodic classification of elements, which catalyst was previously contacted with a sulfur compound at a temperature from 50 to 400.degree. C and then with hydrogen at a temperature of at least 50.degree. C.
