摘要： This invention relates to a vapor phase process for the production of an alkyl styrene by the catalytic dehydrogenation of tertiary butylethylbenzene in the presence of catalysts containing iron oxides under conditions which minimize the undesirable thermal degradation of the raw material and the product while maintaining good yield and selectivity with low production of by-products. Specifically, it has been discovered that these desired results may be obtained by conducting the subject reaction at relatively low temperatures of between about 1000.degree. F. and about 1100.degree. F. and by maintaining a low partial pressure (i.e., not greater than about 0.5 psi) of the alkyl ethylbenzene in the reaction mixture. The desired partial pressure of the alkyl ethylbenzene is obtained by carrying out the catalytic reaction at a pressure of between about 1 psia and about 30 psia with steam as a diluent, the weight ratio of steam to alkyl ethylbenzene being between about 3 and about 30.

摘要： The present invention provides an alkylation process which is highly selective towards the production of para-tertiarybutylethylbenzene in high yield and in high para isomer content, while minimizing the development of unwanted by-products and impurities during the alkylation reaction. In accordance with the process, a feed stream mixture comprising the olefin alkylating agent and a molar excess of an aromatic hydrocarbon substrate is introduced into the inlet of a reactor zone and through a bed of active zeolite alkylation catalyst under alkylation conditions such that substantially all of the olefin reacts with the aromatic substrate to produce a mixture comprising the alkylated product and unreacted aromatic compound. This mixture is continuously withdrawn from the reactor zone as reactor effluent, after which the effluent is split into a product stream and recycle stream. The recycle stream is continuously recirculated back into the inlet of said reactor zone, preferably after being first combined with fresh feed stream mixture, in an amount such that the quantity of said aromatic compound and said olefin present in said reaction zone prior to contact with said catalyst is maintained at a preferred mole ratio greater than 10 to 1.

摘要： A method and associated apparatus for regenerating and/or stabilizing catalyst used in dehydrogenation of alkylaromatic hydrocarbons is disclosed. The alkylaromatic hydrocarbon (1) and steam (2) are combined to form feedstream (3) and pass into reactor (50). The ensuing product stream (4) is reheated in heater (52) to restore the heat lost and passed as partially converted reactant stream (5) into second reactor (54) and leaves as stream (6) comprising the dehydrogen product. Restoration and/or stabilization of catalyst is accomplished by an alkali metal compound which is fed into feedstream (2) and/or product stream (5) via supply means (46 and 66), respectively. The amount of alkali metal compound entering the reactor(s) is monitored by means (42 and 62) which may in turn be coupled to activating means (44 and 64) to signal and activate the supply means. This method and apparatus permit the restoration and/or stabilization of the catalyst to be performed without interrupting the dehydrogenation reaction.

摘要： The invention provides a method of extending the useful life of high temperature heat exchangers, e.g., reactor feed/effluent heat exchangers, in installations where the heat exchanger is contacted by a process fluid stream, e.g., a feedstock comprising ethylbenzene at a temperature where the process stream may cause deterioration of contacted metal surfaces of the heat exchanger and/or undergo catalytic reaction as a result of contact with the contacted metal surfaces. The new method comprises the step of mechanically removing material from those surfaces of the heat exchanger that are to be contacted by the process fluid stream, so as to render said surfaces less susceptible to attack from said high temperature process fluid stream.
