Abstract

A method for the conversion of hydrocarbons in the presence of hydrogen, which comprises converting a hydrocarbon charge to a reaction zone under hydrogen-producing conditions, including a relatively low pressure, separating the outgoing fluid from the reaction zone under said pressure. Low in a first phase of liquid hydrocarbons and a first phase of gas containing hydrogen; increasing the pressure of said first liquid and gaseous phases at a relatively high pressure and recombining said phases, separating from the resulting mixture a second gaseous phase of hydrogen of increased purity and a second phase of liquid hydrocarbons, returning a part of said second gas phase of hydrogen to said reaction zone in the form of recycle, cooling the remaining part of said second gaseous phase of hydrogen and condensing at least a portion of the hydrocarbons contained therein, separating a stream of hydrogen from the resulting cooled gas-condensate mixture. Gaseous of even greater purity and recover it as a product of the process, mix said hydrocarbons condense them with said second phase of liquid hydrocarbons, fractionate the resulting mixture and recover a second product stream comprising normally gaseous hydrocarbons, and a third stream of product which includes hydrocarbon conversion products not normally liquid.
