Abstract: Tungstated zirconium catalysts for paraffin isomerization may comprise: a mixed metal oxide that is at least partially crystalline and comprises tungsten, zirconium, and a variable oxidation state metal selected from Fe, Mn, Co, Cu, Ce, Ni, and any combination thereof. The mixed metal oxide comprises about 5 wt. % to about 25 wt. % tungsten, about 40 wt. % to about 70 wt. % zirconium, and about 0.01 wt. % to about 5 wt. % variable oxidation state metal, each based on a total mass of the mixed metal oxide. The mixed metal oxide has a total surface area of about 50 m2/g or greater as measured according to ISO 9277, and at least one of the following: an ammonia uptake of about 0.05 to about 0.3 mmol/g as measured by temperature programmed adsorption/desorption, or a collidine uptake of about 100 μmol/g or greater as measured gravimetrically.

Abstract: Systems and methods are provided for improving the operation of a divided wall column for performing distillations. The systems and methods include using a separation stage in a fluid flow pathway for transporting an enriched intermediate stream from a first side of a dividing wall to a second side of a dividing wall. By using a separation stage, the benefit of transporting an enriched intermediate stream can be achieved without requiring precise knowledge of the local concentration profile on the first side of the dividing wall.

Abstract: A hybrid model for predicting corrosion in a system integrates a physics-based model developed using laboratory data and a machine-learning model developed using in-field data. Said hybrid model may be used, for example, in methods by: determining a physics-based measurement of corrosion using a physics-based model for a fluid's corrosion of a substrate based, at least in part on, lab-based measurements; determining a machine learning-based measurement of corrosion using a machine learning-based model for the fluid's corrosion of the substrate based, at least in part on, in-field-based measurements; and applying an ensemble method to the physics-based measurement of corrosion and the machine learning-based measurement of corrosion to yield an estimated measure of corrosion of the substrate. The hybrid model may be applied to corrosion mechanisms that occur in, for example, hydrocarbon transportation systems, hydrocarbon production systems, hydrocarbon refining systems, and alkylation systems.

Abstract: Catalytic compositions and sequential catalytic methods are generally described. in some embodiments, a composition comprises a first catalyst comprising a Cu-modified zeolite, and a second catalyst capable of a coupling reaction between (a) an intermediate resulting from a reaction of a reactant at the first catalyst, and (b) a co-reagent, wherein a rate of diffusion of the co-reagent within one or more cages and/or pores of the first catalyst is lower than a rate of diffusion of the intermediate within the one or more cages and/or pores of the first catalyst.

Abstract: Metal-organic framework materials (MOFs) are highly porous entities comprising a multidentate organic ligand coordinated to multiple metal centers, typically as a coordination polymer. Some highly porous MOFs lack stability at ambient conditions. MOFs having ambient condition stability may comprise a plurality of metal clusters (M4O clusters, M=a metal), and a plurality of 4-(1H-pyrazol-4-yl)benzoate ligands coordinated to the plurality of metal clusters to define an at least partially crystalline network structure having a plurality of internal pores. Methods for synthesizing these MOFs may comprise combining a metal source, such as a preformed metal cluster, with 4-(1H-pyrazol-4-yl)benzoic acid, and reacting the preformed metal cluster with the 4-(1H-pyrazol-4-yl)benzoic 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-(1H-pyrazol-4-yl)benzoate.

Abstract: Methods for building models that estimate compositional properties of a process may include (a) receiving data relating to a process; (b) cleaning the data by identifying and removing outlying data points from the data; and conditioning the data; (c) identifying inferential model parameters comprising a parameter selected from the group consisting of: a compositional property of the process as a model output that is not part of the data, operational constraints of the process, interactions between process variables of the chemical process, and any combination thereof; (d) building one or more inferential models based on the cleaned data and the inferential model parameters; and (e) outputting the one or more models and the corresponding validation metric.

Abstract: An elevated target amount of electrolyte is used to initially fill a molten carbonate fuel cell that is operated under carbon capture conditions. The increased target electrolyte fill level can be achieved in part by adding additional electrolyte to the cathode collector prior to start of operation. The increased target electrolyte fill level can provide improved fuel cell performance and lifetime when operating a molten carbonate fuel cell at high current density with a low-CO2 content cathode input stream and/or when operating a molten carbonate fuel cell at high CO2 utilization.

The example process may further include epoxidizing a branched alkene by a catalytic reaction with least a portion of the organic hydroperoxide to produce at least an olefin epoxide and an alcohol. The example process may further include converting at least a portion of the alcohol to either additional branched alkane and/or additional branched alkene.
