20130079578 | Modified Zirconia Catalysts and Associated Methods Thereof - The present invention provides a modified zirconia catalyst including zirconia, sulfate anion, a first metal component and a second metal component, wherein the first metal component can contain aluminum or gallium, and the second metal component includes platinum or palladinum. The weight percentage of sulfur atoms of the sulfate anion based on the weight of the modified zirconia catalyst is less than 1.0 wt %. Decreasing the sulfate content of the modified zirconia catalyst during impregnation can remarkably enhance the iso-C | 03-28-2013 |
20130057268 | Method and Apparatus for Measuring Container Bulge - An extensible frame adapted to receive and maintain a rectilinear container applied upon an interior ledge extensible frame. Two or more orthogonally aligned sensor assemblies are provided to measure deflection of panels forming the container when a static or dynamic load is applied upon an uppermost panel. Each sensor assembly outputs a signal corresponding to a deflection of a panel induced by the load applied upon the uppermost panel. Signals output from the sensor assemblies are received and processed by an output processing unit in either a human cognizable or machine readable format. The amount deflection measured by the sensor assemblies corresponds to an amount of bulge of a panel when a defined load is applied. | 03-07-2013 |
20120142973 | Dual-Bed Catalytic Distillation Tower And Method For Preparing Dimethyl Ether Using The Same - A dual-bed catalytic distillation tower has a catalytic column from the top down having an upper catalytic bed filled with low temperature dehydration catalysts and a lower catalytic bed filled with high temperature dehydration catalysts. When using the dual-bed catalytic distillation tower, the feeding may be fed to the tower from the top of the upper catalytic bed, between the upper and lower catalytic beds or the bottom of the lower catalytic bed for dehydration to obtain DME. The dual-bed catalytic distillation tower has the advantage of flexible set up depending on various feedings such as anhydrous or crude methanol and on different grade of DME to be obtained. | 06-07-2012 |
20110184207 | Method of Fabricating Glycol Monoalkyl Ether Acetate Using Acidic Ionic Liquid Catalyst - A new method for fabricating glycol monoalkyl ether acetate (GMAEA) is provided. A Bronsted acidic ionic liquid is used. After some reactions, two layers of materials are formed. A product of GMAEA is obtained at the upper layer. The lower layer is the ionic liquid. Thus, the ionic liquid is reusable for re-fabricating the product. And, furthermore, waste acid is reduced. | 07-28-2011 |
20090255853 | Novel energy efficient and throughput enhancing extractive process for aromatics recovery - An energy efficient, high throughput process for aromatics recovery can be readily implemented by revamping existing sulfolane solvent extraction facilities, or constructing new ones, so as to incorporate unique process operations involving liquid-liquid extraction and extractive distillation. Current industrial sulfolane solvent based liquid-liquid extraction processes employ a liquid-liquid extraction column, an extractive stripping column, a solvent recovery column, a raffinate wash column, and a solvent regenerator. The improved process for aromatic hydrocarbon recovery from a mixture of aromatic and non-aromatic hydrocarbons requires transformation of the extractive stripping column into a modified extractive distillation column. The revamping incorporates the unique advantages of liquid-liquid extraction and extractive distillation into one process to significantly reduce energy consumption and increase process throughput. The revamp entails essentially only piping changes and minor equipment adjustments of the original liquid-liquid extraction facility, and is therefore, reversible. | 10-15-2009 |
20090105514 | Extractive distillation processes using water-soluble extractive solvents - Extractive distillation processes whereby water-soluble extractive distillation (ED) solvents are regenerated and recovered employ improved operations of the extractive distillation column (EDC) so that polar hydrocarbons are recovered and purified from mixtures containing polar and less polar hydrocarbons and measurable amounts of hydrocarbons that are heavier than intended feedstock and/or polymers that are generated in the ED process. The improved process can effectively remove and recover the heavy hydrocarbons and/or remove polymer contaminants from the solvent in a closed solvent circulating loop through mild operating conditions with no additional process energy being expended. With the improved process, the overhead reflux of the EDC may be eliminated to further reduce energy consumption and to enhance the loading and performance within the upper portion of the EDC, especially when two liquid phases exists therein. | 04-23-2009 |
20090032256 | THROTTLE UNIT FOR DUMP BAILER AND METHOD OF BLOCKING A WATER OUT ZONE IN A PRODUCTION WELL UTILIZING THE SAME - A method of blocking a water out zone in a production well includes the steps of connecting a throttle unit to a dump bailer, wherein the throttle unit is internally defined a flowing space, which can be adjusted in size to thereby control a flow rate of cement for blocking the water out zone; loading the cement into the dump bailer; slowly lowering down the loaded dump bailer to the water out zone in the production well; opening an outlet of the dump bailer under control, so that the cement flows from the dump bailer into the throttle unit and is released at a flow rate preset by adjusting the size of the flowing space; allowing the released cement to load up in the water out zone and slowly permeate into a gravel layer in the production well before becoming cured to block the water out zone. | 02-05-2009 |
