A process and apparatus are disclosed for hydrotreating a hydrocarbon feed in a hydrotreating unit and hydrocracking a second hydrocarbon stream in a hydrocracking unit. The apparatus employs a nanoantenna structure which includes a metal tip spaced from a metal surface or particle. The treatment portion has a functional feature such as, for example, a triangular blade which makes the treatment portion asymmetric. One or more slurry phase reactors may be built and positioned upstream from one or more fixed bed reactors of a pre-existing fixed bed system andor converted from one or more pre-existing fixed bed reactors.
