    • The invention relates to organic chemistry, in particular to catalytic methods for producing aromatic hydrocarbons C6-C12 from hydrocarbons C2-C12. The aim of the invention is to develop an improved method for producing the hydrocarbons characterised by an increased product yield. The inventive method for producing aromatic hydrocarbons consists in transforming a methane mixture with at least one hydrocarbon from the C2-C12 range in the presence of a porous catalyst. Zeolite having an alumosilicate composition and a molar ratio SiO2/Al2O3 equal or less than 450 and chosen from a range ZSM-5, ZSM-11, ZSM-35, ZSM-38, ZSM-48, BETA is used as a catalyst. Gallosilicate, galloalumosilicate, ferrum silicate, ferrumalumosilicate, chromosilicate, chromoalumosilicate having a structure ZSM-5, or ZSM-11, or ZSM-48, or BETA, or alumophosphate having a structure of type of ALPO-5, or ALPO-11, or ALPO-31, or ALPO-36, or ALPO-37, or ALPO-40 with elements introduced into structure at stage of synthesis and chosen from the following range: magnesium, zinc, gallium, manganese, ferrum, silicium, cobalt and cadmium are also used as a catalyst. The catalyst for all variants of the method can also contain zinc, and/or gallium, and/or rare-earth elements, or platinum group metals in a quantity equal or less than 10 mass %.

    • This invention is an acid catalyzed process for producing 2,6-dimethylnaphthaline from cyclohexyl compounds and naphthenic compounds or their precursors such as cyclohexane or methylcyclopentane, as depicted in the Figure. The cyclohexyl (10), cyclic alkane (12) stream and the catalyst (11) are fed into the reactor (14). After stripping of lighter ends, the product stream is passed to a heavy ends separation unit (28) and the product comprising primarily dimethyldecalins is recovered as the overhead stream (32). This stream may then be dehydrogenated to produce a dimethylnaphthalene stream (36) which may be subjected to a crystallization step (38) to produce reasonably pure 2,6-dimethylnaphthalene (40). The latter may optionally be oxidized to produce 2,6-dicarboxynaphthalene (44) suitable for polymerization to various polyester materials.
    • 本发明是由环己基化合物和环烷化合物或其前体如环己烷或甲基环戊烷生产2,6-二甲基萘的酸催化方法,如图所示。 将环己基(10),环烷烃(12)料流和催化剂(11)进料到反应器(14)中。 在汽提较轻的端部之后,将产物流送至重尾分离单元(28),并且主要包含二甲基十年总胆固醇的产物作为塔顶液流(32)回收。 然后可以将该物流脱氢以产生二甲基萘流(36),其可以进行结晶步骤(38)以产生合理纯的2,6-二甲基萘(40)。 后者可任选地被氧化以产生适于聚合成各种聚酯材料的2,6-二羧基萘(44)。
