Abstract

1,155,848. Converting hydrocarbons. UNIVERSAL OIL PRODUCTS CO. 21 Oct., 1966, No. 47231/66. Heading C5E. Hydrocarbon conversion processes are carried out by introducing into a reaction zone a stream of said hydrocarbon and a stream of hydrogen-rich gas, effecting the conversion in the presence of a catalyst, removing the reaction mixture from said zone and adding thereto an impure hydrogen make-up gas stream, introducing this mixture into a first separator and separating into a first liquid fraction and a vapour fraction, refrigerating the vapour fraction to such a temperature below 5‹ C. that upon introduction of the refrigerated vapour fraction to a second separator, a second liquid fraction is separated with the formation of a residual gaseous fraction containing a greater proportion of hydrogen than said make-up gas stream, supplying said gaseous fraction to the reaction zone as said hydrogen-rich gas and withdrawing said liquid fractions from the process. The gaseous fraction formed in the second separator may be combined with the hydrocarbon stream prior to the introduction thereof into the reaction zone. Processes specified are (a) Catalytic isomerization of paraffins, cyclic paraffins, and olefins, e.g. n-butane to iso-butane (process details given) and butene-1 to butene-2. (b) Catalytic isomerization of alkyl aromatic hydrocarbons, e.g. ethyl benzene to xylenes and n-propyl benzene to methylethyl benzene. (c) Hydrorefining. (d) Hydrocracking. (e) Hydroforming. and (f) Hydrodealkylation.
