A process of tuning a hydrocarbon product composition is described. The process involves selecting paraffins for reaction. The equilibrium constants for reactions of the selected paraffins can be used to select appropriate feed ratios, or an equilibrium composition as function of C/H molar ratio. A selected feed is reacted to obtain the product. Equilibrium product compositions and non-equilibrium product compositions can be obtained using the process.

This present disclosure relates to processes and apparatuses for toluene methylation in an aromatics complex for producing paraxylene. More specifically, the present disclosure relates to processes and apparatuses for toluene methylation within an aromatics complex for producing paraxylene wherein an embodiment uses a riser reactor, another embodiment uses a pre-reactor producing dimethyl ether, and another embodiment uses partial regeneration of the catalyst.

The present invention relates to a process for producing olefins, including the step of subjecting an alcohol having not less than 8 and not more than 22 carbon atoms to dehydration reaction in the presence of a solid acid catalyst, in which the solid acid catalyst includes aluminum oxide and an oxide of an element having an electronegativity higher than that of aluminum which is supported on the aluminum oxide.

The present specification describes a novel polycyclic compound and an organic electroluminescent device using the same.

The present disclosure provides methods to produce para-xylene, toluene, and other compounds from renewable sources (e.g., cellulose, hemicellulose) and ethylene in the presence of an acid, such as a Lewis acid. For example, cellulose and/or hemicellulose may be converted into 2,5-dimethylfuran (DMF) and 2-methylfuran, which may be converted into para-xylene and toluene, respectively. In particular, para-xylene can then be oxidized to form terephthalic acid.

The present invention provides methods, reactor systems, and catalysts for increasing the yield of aromatic hydrocarbons produced while converting alkanols to hydrocarbons. The invention includes methods of using catalysts to increase the yield of benzene, toluene, and mixed xylenes in the hydrocarbon product.

A catalyst can be used to convert an alcohol in a dehydration process into an olefin having the same number of carbon atoms as the alcohol. The catalyst can include a phosphorus modified zeolite made by providing a zeolite with at least one ten member ring in the structure, steaming the zeolite, mixing the zeolite with binders and shaping additives, and shaping the zeolite. An ion-exchange step can be performed, and the shaped catalyst can be steamed. Phosphorus can be introduced on the catalyst at an amount of at least 0.1 wt %, such as by dry impregnation or chemical vapor deposition. A metal can be introduced. The catalyst can be washed and/or calcinated, and steamed in an equilibration step. The steaming severity (X) can be at least about 2. The catalyst can be steamed at a temperature above 625 C., such as a temperature ranging from 700 to 800 C.
