Claim 1
Independent Claim
106 words
IN THE PROCESS FOR THE SELECTIVE HYDROGENATION TREATMENT OF GUM FORMERS CONTAINED IN GASOLINE BOILING RANGE HYDROCARBON FRACTIONS IN WHICH THE FRACTION TREATED IS TRICKLED THROUGH A BED OF SOLID SUPPORTED NOBLE METAL HYDROGENATION CATALYST IN CONTACT WITH HYDROGEN, THE IMPROVEMENT WHICH COMPRISES CONTROLLING THE TEMPERATURE SO THAT THE FRACTION TREATED IS INITIALLY TRICKLED OVER AND IN CONTACT WITH THE HYDROGENATION CATALYST BED AT A TEMPERATURE BELOW 50 DEGREES C. AND PRIOR TO COMPLETION OF THE HYDROGENATION AS THE FRACTION TRICKLES DOWN FURTHER THROUGH THE CATALYST BED, THE TEMPERATURE IS INCREASED TO A VALUE IN THE RANGE FROM 50 DEGREES C. UP TO 100 DEGREES C.
