Abstract: This disclosure relates to the adsorption and separation of carbon dioxide in a feed stream (e.g., natural gas) using zeolite ITQ-55 as the adsorbent. A process is disclosed for removing impurities such as carbon dioxide and nitrogen while producing a hydrocarbon product. The process involves passing a feed stream through a bed of an adsorbent comprising zeolite ITQ-55 to adsorb carbon dioxide from the feed stream, thereby producing a product stream depleted in carbon dioxide. The zeolite ITQ-55 has a mean crystal particle size within the range of from about 0.1 microns to about 100 microns. The feed stream is exposed to the zeolite ITQ-55 at effective conditions for performing a kinetic separation, in which the kinetic separation exhibits greater kinetic selectivity for carbon dioxide than for methane or nitrogen. The system and method of this disclosure are particularly suitable for use with feed streams in excess of 10 MMSCFD utilizing rapid cycle PSA operations by tuning crystals size.

Abstract: A method for modeling fluid flow in a wellbore is provided. Hydraulic fracturing is an effective technique to improve well productivity by forming high permeable pathways for hydrocarbons to flow from the rock formation to the wellbore. Fluid flow for hydraulic fracturing is modeled using separated flow components, including a wellbore component (modeling the wellbore(s)), a perforation component (modeling the perforations(s)), a fracture component (modeling the fracture(s)) and a rock component (modeling the rock). Each respective component may be selected independently from a plurality of available components. Further, the respective components may be coupled to one another only at their interfaces, such as at a wellbore-perforation interface, a perforation-fracture interface, and a fracture-rock interface, for continuity of fluid kinematics and properties (such as pressure and density). In this way, the modeling of the subsurface may be tailored to the respective components in order to effectively predict the fracturing treatment.

Abstract: Aspects of the technology described herein comprise a surrogate model for a chemical production process. A surrogate model is a machine learned model that uses a collection of inputs and outputs from a simulation of the chemical production process and/or actual production data as training data. Once trained, the surrogate model can estimate an output of a chemical production process given an input to the process. Surrogate models are not directly constrained by physical conditions in a plant. This can cause them to suggest optimized outputs that the not possible to produce in the real world. It is a significant challenge to train a surrogate model to only produce outputs that are possible. The technology described herein improves upon previous surrogate models by constraining the output of the surrogate model to outputs that are possible in the real world.

Abstract: Methods are provided for appending amines to metal organic framework (MOF) compositions. In some aspects, the methods can allow for appending of amines in the solution or synthesis solution used for synthesizing a MOF. In such aspects, an amine-appended MOF can be formed without having to first separate and dry the underlying non-amine-appended MOF composition. In other aspects, amines can be appended to an existing MOF composition by exposing the MOF to a suitable amine in a protic solvent, such as water or an alcohol.

Abstract: Diesel fuel compositions are provided that have unexpectedly beneficial cold flow properties. Methods for forming such diesel fuel compositions are also provided. The improved cold flow properties are achieved in part based on dewaxing of a distillate fraction of the composition. The improved cold flow properties are achieved further in part based on inclusion of a cold flow additive and fatty acid alkyl ester in the composition, such as fatty acid methyl ester.

Abstract: Systems and methods are provided for improving product yields and/or product quality during co-processing of fast pyrolysis oil in a fluid catalytic cracking (FCC) reaction environment. The systems and methods can allow for co-processing of an increased amount of fast pyrolysis oil while reducing or minimizing coke production for a feedstock including fast pyrolysis oil and a conventional FCC feed. The reducing or minimizing of coke production can be achieved in part by adding a low molecular weight, non-ionic surfactant to the mixture of fast pyrolysis oil and conventional FCC feed.
