PROCESS FOR HYDROGENATING HYDROCARBON, IN PARTICULAR UNSATURATED HYDROCARBON CONTAINING AT LEAST TOW DOUBLE BONDS OR AT LEAST ONE TRIPLE BOND

摘要

PROBLEM TO BE SOLVED: To provide a process for hydrogenating a hydrocarbon comprising highly unsaturated molecules and hydrocarbon molecules containing 4 or more carbon atoms. SOLUTION: Unsaturated molecules are at least partially hydrogenated to less unsaturated molecules containing at least one double bond in at least one reactor 1 comprising at least two distinct beds of at least one hydrogenation catalyst, wherein a portion of a gas phase 4 containing hydrogen is introduced as a mixture with a liquid cut 2 via a line 33 upstream the first catalyst bed and wherein a portion of the gas phase 4 is introduced via a line 6 upstream the subsequent beds contained in the reactor 1 in the process for hydrogenating the liquid cut 2 containing the hydrocarbons, in particular the unsaturated molecules containing at least tow double bonds or at least one triple bond.
