A process where the need to circulate hydrogen through the catalyst is eliminated. This is accomplished by mixing and/or flashing the hydrogen and the oil to be treated in the presence of a solvent or diluent in which the hydrogen solubility is "high" relative to the oil feed. The type and amount of diluent added, as well as the reactor conditions, can be set so that all of the hydrogen required in the hydroprocessing reactions is available in solution. The oil/diluent/hydrogen solution can then be fed to a plug flow reactor packed with catalyst where the oil and hydrogen react. No additional hydrogen is required, therefore, hydrogen recirculation is avoided and trickle bed operation of the reactor is avoided. Therefore, the large trickle bed reactors can be replaced by much smaller tubular reactor.

[ What is claimed is:] [1.] In a hydroprocessing method for treating a feed with hydrogen in a reactor, the improvement comprising a two liquid phase hydroprocessing method comprising the steps of at least one of mixing and flashing the hydrogen and the feed to be treated in the presence of a solvent or diluent wherein the percentage of hydrogen in solution is greater than the percentage of hydrogen in the feed to form a two liquid phase feed/diluent/hydrogen mixture, then separating any gas from the two liquid phase mixture upstream of the reactor, and then reacting the feed/diluent/hydrogen mixture with a catalyst in the reactor to at least one of remove contaminants and saturate aromatics.
