Embodiments of apparatuses and methods for reforming of hydrocarbons including recovery of products are provided. In one example, a method comprises separating a reforming-zone effluent into a net gas phase stream and a liquid phase hydrocarbon stream. The net gas phase stream is separated for forming an H2-rich stream and a first intermediate liquid phase hydrocarbon stream. The H2-rich stream is contacted with an adsorbent to form an H2-ultra rich stream and a PSA tail gas stream. The PSA tail gas stream is contacted with an H2/hydrocarbon separation membrane to separate the PSA tail gas stream and form an H2-ultra rich permeate stream and a PSA tail gas hydrocarbon-containing non-permeate residue stream.
