Process for producing aromatic compound

Disclosed is a process for producing an aromatic compound by a catalytic reaction using a lower hydro-carbon as a starting material, which process can improve the yield of hydrogen and an aromatic compound and can maintain stable catalytic activity. Molybdenum or a molybdenum compound is supported on a metallosilicate, followed by carbonization treatment to obtain a lower hydrocarbon aromatization catalyst. The catalyst is brought into contact with a reaction gas containing a lower hydrocarbon to produce an aromatic compound. In this case, the temperature is raised to a catalytic reaction temperature while allowing an non-oxidative gas (except for a hydrocarbon gas) to flow into the reaction system. When the temperature reaches the catalytic reaction temperature, the reaction gas is allowed to flow into the reaction system to bring the reaction gas into contact with the catalyst to obtain aromatic compounds such as benzene or naphthalene.

... 279,095. Corson, M. G. Oct. 14, 1926, [Convention date]. Void [Published under Sect. 91 of the Acts]. Acyclic and cyclic hydrocarbons.-Hydrocarbons are obtained by reacting calcium carbide with an alcohol, phenol. or chlorine derivative of a hydrocarbon in the absence of carboxyl groups, at 150-300‹ C. and about 12-40 atmospheres pressure. When ethyl alcohol is employed, any water present is first decomposed, giving acetylene which is withdrawn through a reflux condenser. The condenser is then removed and the vessel closed, when diethylacetyleneis formed, which may be further treated with hydrogen and a suitable catalyst under pressure to produce hexane. In another example monochlorbenzene is employed, yielding diphenyl-acetylene (tolane) which may be treated with hydrogen and a catalyst to produce stilbene or dibenzyl.

In the production process of para-xylene, a feed comprising a C 6+ aromatic carbon pixel is separated into a toluene-containing stream, a C 8 aromatic hydrocarbon-containing stream and a C 9+ aromatic hydrocarbon-containing stream. The toluene-containing stream is contacted with a methylating agent to convert the toluene to xylene to produce a methylated effluent stream. The para-xylene is recovered from the C 8 aromatic hydrocarbon-containing stream and the methylated effluent stream in the para-xylene recovery section to produce a para-xylene depleted stream, which is then separated from the para-xylene depleted stream Is contacted with the xylene isomerization catalyst under liquid phase conditions effective to isomerize the xylene in the isomerization stream to produce an isomerization stream. The C 9+ -containing stream is contacted with a transalkylation catalyst under conditions effective to convert the C 9+ aromatic to a C 8 -aromatic to produce a transalkylation stream, the transalkylation stream comprising para-xylene recovery Section.
