Claim:
1. A hydroprocessing method comprising the steps of: (a) combining hydrogen and a feed to be treated to form a mixture thereof wherein the feed is a hydrocarbon feed containing sulfur contaminants and having an API gravity of 25.8-32.9; (b) providing a reactor with a substantially packed bed of hydroprocessing catalyst; (c) contacting the mixture with the packed bed in the reactor; (d) simultaneously injecting a liquid quench into the substantially packed bed of hydroprocessing catalyst of the reactor; (e) withdrawing treated feed from the reactor; (f) feeding the treated feed from the reactor to a hot separator; (g) withdrawing a slipstream from the hot separator; (h) recycling a portion of the slipstream to the reactor as the liquid quench; and (i) collecting another portion of the slipstream as stripper product having a sulfur content of 10 ppm or lower from the hot separator; wherein the packed bed of catalyst of the reactor further comprises two beds of catalyst and the liquid quench of step (d) is fed to the reactor between the two beds of catalyst.
