A catalyst may include a support and from 5 to 20 wt.-% of a promoter, based on the total weight of the catalyst, wherein the support may include titanium dioxide, zirconium dioxide, and/or a mixture thereof, and the promoter may be an alkali metal oxide. Processes for preparing such catalysts may include impregnating a support of titanium dioxide and/or zirconium dioxide with an aqueous solution including a preferably soluble alkali compound and calcining. Alkyl mercaptans may be prepared in the presence of such catalysts or catalysts obtained by such processes.

The invention relates to a catalyst system for oligomerizing olefins over a catalyst comprising nickel, to the use of this catalyst and to a method for dimerizing olefins.

Selective oligomerization of olefins

A process for preparing a catalyst provided in the form of a metal oxide catalyst having at least one element selected from Mo, Te, Nb, V, Cr, Dy, Ga, Sb, Ni, Co, Pt and Ce. The catalyst is subjected to an aftertreatment to increase the proportion of the M1 phase, by contacting the catalyst with steam at a pressure below 100 bar or by contacting the catalyst with oxygen to obtain an aftertreated catalyst. The aftertreated catalyst may be used for oxidative dehydrogenation processes.

The invention relates to a novel catalyst based on zeolite, the production of that catalyst, and the use of the catalyst in a method for producing lower olefins from oxygenates and for oligomerizing olefins. The novel catalyst has a SiO/AlOweight ratio of 2 to 9, a BET surface of 250 to 500 m/g, and an Na content under 200 ppm. The catalyst includes a crystalline alumosilicate zeolite and a binder. The catalyst is characterized in that the ratio of the peak heights of its IR absorption bands v=3610 cm&#xb1;20 cm/v=3680 cm&#xb1;20 cmis greater than 1.8.

Re-usable ceramic magic angle spinning (MAS) NMR rotors constructed of high-mechanic strength ceramics are detailed that include a sample compartment that maintains high pressures up to at least about 200 atmospheres (atm) and high temperatures up to about least about 300&#xb0; C. during operation. The rotor designs minimize pressure losses stemming from penetration over an extended period of time. The present invention makes possible a variety of in-situ high pressure, high temperature MAS NMR experiments not previously achieved in the prior art.
