Abstract: An integrated process for producing para-xylenes may include catalytically reforming a naphtha feed stream; separating the reformate stream into a C1-C7 hydrocarbon stream and a C8+ hydrocarbon stream; exposing the C1-C7 hydrocarbon stream to a first solvent in a solvent extraction unit to form a non-aromatic hydrocarbon stream and an aromatics stream; upgrading the aromatics stream to form a toluene-rich transalkylation feed stream; separating the C8+ hydrocarbon stream into a C9+ hydrocarbon stream, a para-xylene stream and a xylene isomer stream; dealkylating the C9+ hydrocarbon stream; separating the dealkylation product stream into an additional xylene stream and a tri-methyl benzene rich stream; and upgrading the toluene-rich transalkylation feed stream and the tri-methyl benzene rich stream with a hydrogen stream to produce an alkyl-benzene stream and additional xylene stream, wherein a ratio by weight of the toluene-rich transalkylation feed stream to the tri-methylbenzene rich stream is from 0.3 to 3.

Abstract: This application consists of a method for the synthesis of a type of FER/MOR composite molecular sieve. That method consisting of mixing FER seed crystals, MOR seed crystals, a silicon source, water and an acid or alkali, thus yielding a reaction mixture; by adjusting the proportions of the seed crystals added, the silicon-aluminium proportion, acidity/alkalinity and other reaction conditions, it is possible to obtain a dual phase composite molecular sieve within which the proportions of the crystal phases may be adjusted. In the synthesis process to which the method of this application relates, there is no need to add any organic template, thus reducing the cost of the reaction, in addition to reducing likely environmental pollution, thus having major potential applications.

Abstract: A catalyst for the carbonylation of dimethyl ether to methyl acetate. The catalyst comprises a zeolite, such as a mordenite zeolite, at least one Group IB metal, such as copper, and/or at least one Group VIII metal, such as iron, and at least one Group IIB metal, such as zinc. Such a catalyst with combined metals provides enhanced catalytic activity, improved stability, and improved selectivity to methyl acetate, and does not require a halogen promoter, as compared to a metal-free or copper only zeolite.
