摘要： A process for the conversion of paraffins and olefins in a hydrocarbon feedstream to aromatics is presented. The process includes separating the hydrocarbon feedstream into two separate streams, a lighter hydrocarbon stream and a heavier hydrocarbon stream, and processing each of the streams separately. The process includes passing the light stream through a series of reforming units and adding the heavy stream at a downstream position to pass through a subsequent reforming unit.

摘要： A gasoline blending components production system useful for producing both aromatics and gasoline blending components from naphtha. The production system includes a light hydrocracked naphtha splitter, a medium hydrocracked naphtha splitter, a naphtha hydrotreater, an isomerization unit, a continuous catalytic reformer and aromatics complex. The production system is operable to produce both refined benzene and para-xylene products in addition to medium hydrocracked naphtha, isomerate, a C7s cut and a C9+ cut, which are useful for gasoline blending without additional treatment. A method for producing gasoline blending components while maximizing aromatic production includes introducing both stabilized hydrocracked naphtha to the light hydrocracked naphtha splitter and straight run naphtha to the naphtha hydrotreater. Operating the production system produces three types of hydrocracked naphtha: a light hydrocracked naphtha, a medium hydrocracked naphtha and a heavy hydrocracked naphtha. Light and heavy hydrocracked naphtha are directed to the naphtha hydrotreater.

摘要： A process for reforming a hydrocarbon stream is presented. The process involves splitting a naphtha feedstream to at least two feedstreams and passing each feedstream to separation reformers. The reformers are operated under different conditions to utilize the differences in the reaction properties of the different hydrocarbon components. The process further includes passing one or more catalyst streams through the reformers to optimize selectivity and conversions.

摘要： A process for reforming a hydrocarbon stream is presented. The process involves splitting a naphtha feedstream to at least two feedstreams and passing each feedstream to separation reformers. The reformers are operated under different conditions to utilize the differences in the reaction properties of the different hydrocarbon components. The process utilizes a common catalyst, and common downstream processes for recovering the desired aromatic compounds generated.

摘要： The invention is a lower cost combined reforming-benzene alkylation process. The unstabilized liquid product recovered from the reforming reaction zone is not stabilized by passage into a stripping column for the removal of C.sub.4 -minus hydrocarbons but is instead split into light and heavy fractions, with the light, benzene-containing fraction being passed directly into an alkylation zone.

摘要： A naphtha feedstock is reformed by splitting the feedstock into a first C.sub.6 or lower fraction and a C.sub.7 and higher fraction, and passing the C.sub.6 and lower fraction to a reactor and combining the effluent from the first reactor with the C.sub.7 and higher fraction and passing the mixture to a second reactor. The reformate produced has an octane rating at least equivalent to that produced by conventional processes, but has a lowered benzene content.

摘要： A naphtha boiling range charge stock is converted into a motor fuel which does not necessitate the incorporation of metalcontaining additives otherwise required for suitable anti-knock characteristics. The process involves a combination of hydrocracking and catalytic reforming, and is effected in a manner which significantly decreases the quantity of methane and ethane produced. The novel form of hydrocracking results in a product predominantly comprising naphthenic hydrocarbons and highly branched paraffins, the latter being predominantly isobutane. Following separation to recover the isobutane, catalytic reforming is utilized to dehydrogenate the naphthenic compounds to produce an aromatic concentrate.

摘要： Disclosed herein are processes for the production of hydrocarbon fuel products from C2-5 alkanes. Methane is converted to ethylene in a methane thermal olefination reactor operating at a temperature of at least 900° C. and a pressure of at least 150 psig, and without a dehydrogenation catalyst or steam. C2-5 alkanes are converted to olefins in a C2-5 thermal olefination reactor operating at a temperature, pressure and space velocity to convert at least 80% of the alkanes to C2-5 olefins. The ethylene and C2-5 olefins are passed through an oligomerization reactor containing a zeolite catalyst and operating at a temperature, pressure and space velocity to crack, oligomerize and cyclize the olefins. In one aspect, methane in the effluent of the oligomerization reactor is recycled through the C2-5 thermal olefination reactor. Methods for the thermal olefination of methane are also disclosed.
