Abstract: An additive manufactured article is comprised of at least two adhered layers of extrudates (120) comprised of a thermoset material having therein a phase change material, wherein the phase change material undergoes a phase change at a temperature less than where the thermoset material decomposes. The article may be made by dispensing a mixture comprised of an organic reactive material and phase change material forming extrudates that are 3D printed into an article having multiple layers of extrudates bound together and then allowing the organic reactive material to react forming a thermoset material having therein the phase change material to form the additive manufactured article. The shape of the article may be changed by heating to a temperature above the temperature where the phase change material undergoes a phase change while applying a force and then cooling below the phase change temperature.

Abstract: The present invention relates to azeotropic blends and pseudoazeotropic blends and to coating compositions including such blends. In one aspect, an azeotropic blend or a pseudoazeotropic blend consists essentially of octamethyltrisiloxane and a second component selected from the following: amyl acetate, 2-propoxyethanol, 1-methoxy-2-propylacetate, and 1-propoxy-2-propanol.
Abstract: The invention is an improved method of making an improved carbon molecular sieve (CMS) membrane in which a precursor polymer (e.g., polyimide) is pyrolyzed at a pyrolysis temperature to form a CMS membrane that is cooled to ambient temperature (about 40° C. or 30° C. to about 20° C.). The CMS membrane is then reheated to a reheating temperature less than the pyrolysis temperature to form the improved CMS membrane. The improved CMS membranes have shown an improved combination of selectivity and permeance as well as stability for separating hydrogen from gas molecules (e.g., methane, ethane, propane, ethylene, propylene, butane, carbon dioxide, nitrogen, butylene, and combinations thereof).

Abstract: The present disclosure provides a packaging process and the resultant package produced from the process. The process includes introducing, into a mixing device, pellets composed of ethylene/propylene/diene polymer (EPDM). The EPDM comprises greater than 60 wt % units derived from ethylene. The pellets have a residual moisture content from 500 ppm to 2500 ppm. The process includes adding a silica-based powder to the mixing device and coating at least a portion of the pellets with the silica-based powder. The process includes sealing a bulk amount of the coated pellets in a bag made of a flexible polymeric film. The process includes absorbing, with the silica-based powder, the residual moisture from the pellets, and preventing moisture condensation in the bag interior for a period from 7 days after the sealing step to 1000 days after the sealing step.

Abstract: A method for processing a chemical stream includes contacting a feed stream with a catalyst in a reactor portion of a reactor system that includes a reactor portion and a catalyst processing portion. The catalyst includes platinum, gallium, or both and contacting the feed stream with the catalyst causes a reaction which forms an effluent stream. The method includes separating the effluent stream from the catalyst, passing the catalyst to the catalyst processing portion, and processing the catalyst in the catalyst processing portion. Processing the catalyst includes passing the catalyst to a combustor, combusting a supplemental fuel in the combustor to heat the catalyst, treating the heated catalyst with an oxygen-containing gas to produce a reactivated catalyst, and passing the reactivated catalyst from the catalyst processing portion to the reactor portion. The supplemental fuel may include a molar ratio of hydrogen to other combustible fuels of at least 1:1.
