In a process for hydroforming or for recovery of aromatic hydrocarbons at 480-500 degrees C, in presence of a catalyst, the feed, contg. hydrocarbons and H2 is circulated through is not 2 moving bed reaction zones; the catalyst moves continuously downwards through these zones and is passed into a re...
