摘要： In a process for producing para-xylene, a feed stream comprising C6+ aromatic hydrocarbons is separated into a C7− aromatic hydrocarbon-containing stream, a C8 aromatic hydrocarbon-containing stream, and a C9+ aromatic hydrocarbon-containing stream. The C7− aromatic hydrocarbon-containing stream is contacted with a methylating agent to convert toluene to xylenes and produce a methylated effluent stream. Ethylbenzene is removed from the C8 aromatic hydrocarbon-containing stream, para-xylene is recovered from the ethylbenzene-depleted C8 aromatic hydrocarbon-containing stream and the methylated effluent stream in a para-xylene recovery section to produce a para-xylene depleted stream, which is then contacted with a xylene isomerization catalyst under liquid phase conditions effective to isomerize xylenes in the para-xylene depleted stream and produce an isomerized stream. The C9+-containing stream with a transalkylation catalyst under conditions effective to convert C9+-aromatics to C8−-aromatics and produce a transalkylated stream, which is recycled together with the isomerized stream to the para-xylene recovery section.

摘要： Methods and apparatuses for processing hydrocarbons are provided. In one embodiment, a method for processing hydrocarbons includes fractionating a feed stock to form a C6-C10 naphtha stream and a C11+ hydrocarbon stream. The method reforms the C6-C10 naphtha stream. Further, the method cracks the C11+ hydrocarbon stream to form a stream of C6-C10 hydrocarbons and extracts aromatics from the stream of C6-C10 hydrocarbons to form an extract stream. The method includes combining the C6-C10 naphtha stream and the extract stream containing the aromatics. Also, the method includes processing the C6-C10 naphtha stream and the extract stream in an aromatics complex to form selected aromatic products. Further, the embodiment may include reforming raffinate streams.

摘要： A new family of crystalline microporous silicometallophosphates designated MAPSO-64 and modified forms thereof have been synthesized. These silicometallophosphates are represented by the empirical formula R+rMm2+EPxSiyOz where R is an organoammonium cation such as ETMA+ or DEDMA+, M is an alkaline earth or transition metal cation of valence 2+, and E is a trivalent framework element such as aluminum or gallium. The MAPSO-64 compositions are characterized by a BPH framework topology and have catalytic properties for carrying out various hydrocarbon conversion processes, and separation properties for separating at least one component.

摘要： A method is provided for conversion of heavy alkylaromatic compounds, particularly those in the C8-C12 range, into more valuable aromatics of benzene, toluene and xylene utilizing a toluene disproportionation unit containing a nickel, palladium or platinum-modified mordenite catalyst. The method allows large amounts of these heavy alkylaromatic compounds to be processed without adversely affecting catalyst activity or catalyst life. This is accomplished by introducing the heavy alkylaromatic compounds into the reactor at constant reaction severity conditions and maintaining those conditions during conversion.
