The present invention relates to a process for producing aromatics, p-xylene and terephthalic acid. The process for producing aromatics comprises a step of contacting an oxygen-containing raw material with an aromatization catalyst, under aromatization reaction conditions, to produce aromatics. The process for producing aromatics has an advantage of high yield of carbon as aromatics.

Provided is a method of producing a conjugated diene, including a step of dehydrating a ,-unsaturated alcohol in the presence of a solid acid catalyst having a Hammett acidity function (H.sub.0) of 12.2 or less.

Disclosed is a polyalphaolefin made up of hydrogenated oligomers. The oligomers include at least 80 wt. % of a C.sub.6 to C.sub.12 normal alpha olefin monomer. The polyalphaolefin has a viscosity index greater than or equal to 110 and a kinematic viscosity at 40 C. of less than or equal to 1750 cSt.

The present invention discloses processes for oligomerizing a monomer containing C.sub.3 to C.sub.30 olefins using a chemically-treated solid oxide, such as fluorided silica-coated alumina and fluorided-chlorided silica-coated alumina.

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 invention discloses processes for oligomerizing a monomer containing C.sub.3 to C.sub.30 olefins using a chemically-treated solid oxide, such as fluorided silica-coated alumina and fluorided-chlorided silica-coated alumina.

A method to generate cyclic hydrocarbons from farnesene to increase both the density and net heat of combustion of the product fuels.

Disclosed herein are catalyst systems containing an alpha-diimine nickel halide complex, a chemically-treated solid oxide, and an optional co-catalyst. These catalyst systems can be used to reduce the light oligomer content of propylene oligomer streams, for instance, by oligomerizing olefin feedstocks containing C.sub.6 to C.sub.27 propylene oligomers to produce oligomer compositions having higher molecular weights.

A method for producing a linear hydrocarbon, including reacting a linear aliphatic aldehyde in the presence of at least one metal ion selected from the group consisting of a vanadium ion, a manganese ion, an iron ion, a cobalt ion, an iridium ion, a copper ion, and a thallium ion.
