摘要
Process for hydrogenating a highly unsaturated hydrocarbon cut, boiling above 200 C under atmospheric pressure, comprising passing said cut successively over two catalysts, each of which contains an alumina carrier, (a) at least one molybdenum and/or tungsten compound and (b) at least one nickel and/or cobalt compound, the ratio b/a expressed in gram-atoms of metals, being from 1.5:1 to 10:1 for the first catalyst and from 0.1:1 to 1:1 for the second catalyst and the alumina carrier of the first catalyst having a heat of neutralization by ammonia absorption lower than 10 calories per gram under an ammonia pressure of 300 mmHg.
