Is liquid-phase hydrogenation and gas-phase hydrogenation such that in one case sufficient hydrogen is dissolved in the feedstock and then both are fed into the reactor, while in the other case hydrogen and the feedstock are not mixed together before being fed into the reactor?
The difference between the two lies in the state of the oil and hydrogen inside the reactor. Liquid phase: The oil contains gas, and its state is liquid. Gas phase: The gas contains oil, which is in a misty or droplet form.
