| 20110281317 | CONVERSION OF CELLULOSIC MATERIALS INTO GLUCOSE FOR USE IN BIOETHANOL PRODUCTION - A method for producing an aqueous sugar solution from cellulosic materials comprising the steps of heating ground cellulosic materials with perchloric acid; neutralizing the heated materials with an alkali to yield a salt precipitate; and filtering the salt precipitate off to obtain the aqueous sugar solution. | 11-17-2011 |
| 20110021720 | ENVIRONMENTALLY FRIENDLY NATURAL OIL-BASED TONER RESIN - A method of synthesizing polyester toner resins comprises: polycondensing polycarboxylic acids, polyols and free fatty acids to form low molecular weight polyester resins with alkenyl group or hydroxyl group or a combination of both; wherein at least one of said polycarboxylic acids, said polyols or said free fatty acids derive from natural oils; crosslinking the polyester via alkenyl group with radical initiator and vinyl monomer or via hydroxyl group with diisocyanate to generate polyester of higher molecular weight and melting point; obtaining a first fraction with a molecular weight ranged between 3000 and 15000 and a second fraction with a molecular weight larger than 15000; and combining said first fraction with said second fraction to form said polyester toner resins. | 01-27-2011 |
| 20100087312 | CHROMIUM-FREE CATALYSTS OF METALLIC CU AND AT LEAST ONE SECOND METAL - Described is a method for the preparation of a chromium-free catalyst comprising Cu and at least one second metal in metallic or oxidic form, comprising the steps of a) preparing a final solution comprising ions of Cu and of at least one second metal, said final solution additionally comprising ions of a complexing agent and having a pH of above 5; b) contacting said final solution with inert carrier to form a final solution/carrier combination; c) optionally, drying the final solution/carrier combination; d) calcining the final solution/carrier combination obtained in step c) or d) to yield Cu and the at least one second metal in oxidic form; and e) reducing at least part of the thus obtained oxidic Cu on the carrier. Further, a catalyst obtainable by the said method as well as uses thereof are described. | 04-08-2010 |
