| 20110021846 | PROCESS FOR ABSORBING METHYLACROLEIN WITH IONIC LIQUID - Disclosed is a process for absorbing methylacrolein, characterized in that it absorbs methylacrolein by an absorbent comprising an ionic liquid. The absorbent can absorb methylacrolein effectively, and it is easy to be separated from methylacrolein, regenerated and recycled. It is a green absorbent. The technique is a green methylacrolein absorbing and separating technique. | 01-27-2011 |
| 20100143259 | FLUORESCENT MICROSPHERES, THE PREPARATION METHOD AND USES THEREOF - The invention discloses the microspheres comprising the following structure in the composition thereof and the uses as tracers and fluorescent standard calibration products. | 06-10-2010 |
| 20100068778 | PROCESS FOR COMPREHENSIVELY UTILIZING STEAM EXPLODED RADIX PUERARIAE AND DEVICE THEREFOR - The invention provides a process for co-producing ethanol and Radix Puerariae flavones and utilizing Radix Puerariae fibers from Radix Puerariae by way of clean solid state fermentation, and the device used therein. The process comprises the following steps: providing Radix Puerariae as raw material; pretreating the Radix Puerariae raw material by steam explosion; producing and separating ethanol by continuous coupled solid state fermentation; filtering off fermentation residues; and extracting and purifying Radix Puerariae flavones from the filtrate. The process achieves an effective and comprehensive utilization of Radix Puerariae. | 03-18-2010 |
| 20100044310 | METHOD, EQUIPMENT AND SPECIFIC DRAWER FOR MEMBRANE SEPARATION UTILIZING CONCENTRATION POLARIZATION - The present invention relates to a membrane separation method and a relevant equipment, in particular to a method and an equipment for membrane separation utilizing concentration polarization during membrane filtration process, especially, to a concentration process and equipment and a drawer special for drawing a concentration polarization layer. The direct removal of the concentration polarization layer from membrane surface not only decreases the adverse influence of concentration polarization on membrane separation but also obtains concentrated retention components, thereby significantly improving the ability to maintain membrane flux, solving the twinborn problems concerning concentration polarization and membrane fouling during the membrane separation process, and achieving a high-efficiency concentration for retention components. The method and equipment of the present invention can be widely applied in various membrane techniques, in particular in a membrane separation process for concentrating biomacromolecule and organic micromolecule products such as sugars, organic acids and polypeptides etc. | 02-25-2010 |
| 20090246847 | METHOD FOR PRODUCING ETHANOL FROM STEAM EXPLODED SWEET POTATO BY FERMENTATION - A method for producing ethanol from steam-exploded sweet potato by fermentation includes subjecting sweet potato to a steam explosion treatment, subjecting the sweet potato after the steam explosion to saccharification and fermentation, and collecting ethanol produced by the fermentation. The sweet potato can optionally be subjected to a pre-treatment utilizing a short-time, low-pressure steam explosion technology, which omits the long-time cooking process for the starch-based raw material and reduces the energy consumption for producing ethanol by fermentation. The method permits the steam explosion-treated sweet potato t be subjected directly to saccharification and solid-state fermentation, the water content in fermentation mash is reduced greatly so as to increase the concentration of ethanol in fermentation mash, reduce the energy consumption for distillation, reduce the subsequent treatment steps for the waste water and lower the producing cost, which are all beneficial to the comprehensive utilization of sweet potato. | 10-01-2009 |
| 20080311646 | Carbon Supply Device for Cultivating Miro Algae in Large and Its Application Method and Use - Disclosed herein is a carbon supply device for supplying carbon dioxide during large scale cultivation of micro-algae in open pond, and its application method and use. The device comprises a trap container in which a partition plate is installed vertically and has a 10-50 cm gap from the container bottom, and the partition plate is higher than the wall of the trap container; and a gas distributor is positioned at the bottom of the container. In use, the trap carbon supply device is embedded in bottom of an open pond, wherein the partition plate is above the liquid level of the culture solution in the open pond such that the culture solution driven by a stirrer flows into the trap carbon supply device from one side thereof, and flows out of the device from the other side thereof, wherein the culture solution is mixed with carbon dioxide at the bottom of the container. | 12-18-2008 |
| 20080233295 | ANTIOXIDATION COATING FOR STEEL AND ANTIOXIDATION METHOD USING THE SAME - The present disclosure relates to an antioxidation coating for steel. In one example, the coating is produced by mixing magnesian mineral, layered silicate, metallurgical solid waste, aluminum powder, organic thickener and inorganic binder including the components of Al | 09-25-2008 |
