Encapsulation method for preparation of pellets with high attrition resistance
This disclosure provides a method to produce highly attrition resistant pellets by encapsulating reactive components in a vitrified clay outer layer. The reactive component mixture is present relative to the clay substrate in a weight ratio of part per 60-100 part to about 60 parts of the clay substrate. The reactive components are agglomerated first, and clay substrate is added to form the outer layer of the pellet. The pellets are calcined at temperatures above 1200 C to form a vitrified clay semi porous outer layer providing high strength to the pellet while facilitating the gas transfer for the reaction with the encapsulated reactive components. Pellets containing CuO—Fe.sub.2O.sub.3-alumina oxygen carrier for chemical looping combustion of fuel demonstrated high attrition resistance and high reactivity with methane.
USE OF POROUS 2,5-FURANEDICARBOXYLATE-BASED MOFS FOR IMPROVED SEPARATION OF BRANCHED ALKANES
The present invention relates to the use of 2,5-furanedicarboxylate-based MOFs, such as, MIL-160(Al) metal-organic framework, for separating C6 alkane isomers into linear, mono-branched and di-branched isomers. The present invention also relates to the use of 2,5-furanedicarboxylate-based MOFs, such as, MIL-160(Al) metal-organic framework, preferably in combination with Zeolite 5A for producing higher research octane number gasoline blends. Also within the scope of the invention is a system for separating C6 and C5 alkane isomer mixtures into linear, mono-branched and di-branched fractions.
3D printed zeolite monoliths for CO.SUB.2 .removal
Carbon dioxide (CO.sub.2) capture materials comprising one or more 3D-printed zeolite monoliths for the capture and or removal of CO.sub.2 from air or gases in enclosed compartments, including gases or mixtures of gases having less than about 5% CO.sub.2. Methods for preparing 3D-printed zeolite monoliths useful as CO.sub.2 capture materials and filters, as well as methods of removing CO.sub.2 from a gas or mixture of gases in an enclosed compartment using 3D-printed zeolite monoliths are provided.
Thermal management system with sublimator and adsorbent bed
A thermal management system includes a space structure, a feed water container, a water feed line, a pump, and a filter device. The space structure includes a heat source connected with a fluid loop for conveying a working fluid through the heat source to regulate temperature and a sublimator connected with the fluid loop to receive the working fluid. The sublimator has a porous surface. The water feed line is connected with the container and the sublimator. The pump is located in the feed water line and is operable to move the feed water from the container to the sublimator. The sublimator is operable to cool the working fluid using the porous surface. The filter device is located in the water feed line between the pump and the feed water container. The filter device includes an adsorbent bed to remove organic compounds.
