Abstract: Methods and systems for mitigating annular pressure buildup in a wellbore. An example method introduces a treatment fluid into an annulus of the wellbore, wherein the annulus has an annular pressure, and wherein the treatment fluid comprises an aqueous base fluid and a nanoporous metal oxide. The method further includes allowing or causing to allow at least a portion of the treatment fluid to remain in the annulus; and allowing or causing to allow the annular pressure to increase thereby inducing at least a portion of the aqueous base fluid to enter into an interior volume of the nanoporous metal oxide.

Abstract: Catalyst particles comprising one or more active metal components and methods for manufacturing such catalyst particles are provided. The particles are a composite of a granulating agent or binder material such as an inorganic oxide, and an ultra-stable Y (hereafter “USY”) zeolite in which some of the aluminum atoms in the framework are substituted with zirconium atoms and/or titanium atoms and/or hafnium atoms. The one or more active phase components are incorporated in a composite mixture of the inorganic oxide binder and the post-framework modified USY zeolite prior to forming the catalyst particles.

Abstract: The invention provides a process for preparing a cobalt-containing catalyst precursor. The process includes calcining a loaded catalyst support comprising a silica (SiO2) catalyst support supporting cobalt nitrate to convert the cobalt nitrate into cobalt oxide. The calcination includes heating the loaded catalyst support at a high heating rate, which does not fall below 10° C./minute, during at least a temperature range A. The temperature range A is from the lowest temperature at which calcination of the loaded catalyst support begins to 165° C. Gas flow is effected over the loaded catalyst support during at least the temperature range A. The catalyst precursor is reduced to obtain a Fischer-Tropsch catalyst.

Abstract: Provided is a process for hydrocracking normal paraffins into lighter normal paraffins with minimal formation of iso-paraffins. The process comprises hydrocracking a hydrocarbon feedstock comprising normal paraffins under hydrocracking conditions. The reaction is run in the presence of a selected catalyst, e.g., an LTA-type zeolite, with a requisite topology and acid site density. The zeolite has a framework type with voids greater than 0.50 nm in diameter, which are accessible through apertures characterized by a longest diameter of less than 0.50 nm and a shortest diameter of more than 0.30 nm. The reaction conducted in the presence of such a selected zeolite produces an n-paraffin rich product.

Abstract: Metal-organic framework materials (MOFs) are highly porous entities comprising a multidentate organic ligand coordinated to multiple metal centers. MOFs having ambient condition stability may comprise a plurality of metal clusters comprising one or more M4O clusters (M is a metal), and a plurality of 4-pyrazolecarboxylate ligands coordinated to the plurality of metal clusters to define an at least partially crystalline network structure having a plurality of internal pores. The MOFs may have a Pa3 symmetry, which upon activation may convert into Fm3m symmetry. Methods for synthesizing the MOFs may comprise combining a metal source, such as a preformed metal cluster, with 4-pyrazolecarboxylic acid, and reacting the preformed metal cluster with the 4-pyrazolecarboxylic acid to form a MOF having an at least partially crystalline network structure with a plurality of internal pores defined therein and comprising a plurality of metal clusters coordinated to a multidentate organic ligand comprising 4-pyrazolecarboxylate.
