Abstract: 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° 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.

Abstract: Provided is a Fischer Tropsch catalyst prepared according to a process comprising: a. preparing a catalyst precursor by: i. impregnating an alumina catalyst support material with a first solution comprising ammonium metavanadate and phosphoric acid, to obtain a treated catalyst support material; ii. calcining the treated catalyst support material at a temperature of at least 500° C. to obtain a modified catalyst support having a modified support surface area and a pore volume of at least 0.4 cc/g; wherein the modified catalyst support loses no more than 8% of the pore volume when exposed to a water vapor; and iii. contacting the modified catalyst support with a second solution comprising a precursor compound of an active cobalt catalyst component and glutaric acid to obtain the catalyst precursor; and b. reducing the catalyst precursor to activate the catalyst precursor to obtain the Fischer Tropsch catalyst.

Abstract: An integrated system for monitoring a chemical concentration in an ionic liquid, comprising: a. an online FTIR instrument with an ATR window; b. a sample conditioning station that removes light hydrocarbons and produces a degassed ionic liquid that is analyzed by FTIR; and c. a solvent flushing system that flows solvent across the ATR window. Also, a process for monitoring the chemical concentration, comprising: a. degassing the ionic liquid in the sample conditioning station; b. passing the degassed ionic liquid over an ATR window; c. periodically redirecting a flow of the degassed ionic liquid via a bypass line or an on-off valve that isolates the ATR window from the process unit that elutes the ionic liquid; and d. flowing a solvent and a purging gas over the ATR window during the periodically redirecting step c); and e. resuming the passing of the degassed ionic liquid over the ATR window.

Abstract: 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.
