A novel synthetic crystalline aluminogermanosilicate molecular sieve material, designated SSZ-114, is provided. SSZ-114 can be synthesized by treating an aluminogermanosilicate molecular sieve of CTH framework topology with water or an aqueous solution of a mineral acid under conditions sufficient to degermanate at least a portion of aluminogermanosilicate molecular sieve to form a degermanated molecular sieve and calcining the degermanated molecular sieve under conditions sufficient to convert the degermanated molecular sieve to SSZ-114. Molecular sieve SSZ-114 may be used in organic compound conversion reactions and/or sorptive processes.

An aluminosilicate molecular sieve of STW framework type, designated herein as SSZ-110, and having a molar ratio of SiO/AlOof less than 100, is provided. SSZ-110 may be synthesized using an organic structure directing agent selected from one or more of 1,4-bis(2,3-dimethyl-1H-imidazolium)butane dications, 1,5-bis(2,3-dimethyl-1H-imidazolium)pentane dications, and 1,6-bis(2,3-dimethyl-1H-imidazolium)hexane dications. SSZ-110 may be used in organic compound conversion reactions and sorptive processes.

A process has been developed for preparing a Fischer-Tropsch catalyst precursor and a Fischer-Tropsch catalyst made from the precursor. The process includes preparing a catalyst precursor by contacting a boehmite material with a stabilizer containing vanadium-phosphorus. The boehmite material includes two or more different crystalline boehmites having the same average crystallite size to the nearest whole nanometer and having differing properties selected from surface area, pore volume, density and combinations thereof. The boehmite material is subjected to at least one heat treatment at a temperature of at least 500&#xb0; C., either before or after the contacting step to obtain a stabilized catalyst support having a pore volume of at least 0.3 cc/g. A catalytic metal or a compound containing cobalt is applied to the stabilized catalyst support to form the catalyst precursor. Finally, the catalyst precursor is reduced to activate the catalyst precursor to obtain the Fischer Tropsch catalyst. The catalyst has enhanced hydrothermal stability as measured by losing no more than 6% of its pore volume when exposed to water vapor.

Methods for monitoring ionic liquids using vibrational spectroscopy may involve contacting an infrared (IR) transmissive medium with the ionic liquid, recording an IR spectrum of the ionic liquid, and quantifying at least one chemical characteristic of the ionic liquid based on the IR spectrum. The IR spectrum may be recorded ex situ or in situ. Methods for controlling ionic liquid catalyzed processes are also disclosed, wherein a condition of the ionic liquid may be determined during such processes based on IR spectral analysis of the ionic liquid.

A process is disclosed for preparing a Fischer-Tropsch catalyst precursor and a catalyst made from the precursor. The process includes contacting an alumina catalyst support material with a first solution containing a vanadium compound and a phosphorus compound, to obtain a modified catalyst support material. The modified catalyst support material is calcined at a temperature of at least 500&#xb0; C. The calcined modified catalyst support has a pore volume of at least 0.4 cc/g. The modified catalyst support is less soluble in acid solutions than an equivalent unmodified catalyst support. The modified catalyst support is contacted with a second solution which includes a precursor compound of an active cobalt catalyst component and glutaric acid to obtain a catalyst precursor. The catalyst precursor is reduced to activate the catalyst precursor to obtain the Fischer-Tropsch catalyst. The catalyst has enhanced hydrothermal stability and good activity.
