标题:Process for the synthesis of carboxylic anhydrides using a vanadium, phosphorus oxygen containing catalyst composition
发明人：YANG TAI-CHENG; RAO KRISHNA K; HUANG I-DER
权利人:EXXON RESEARCH ENGINEERING CO
摘要:A vanadium, phosphorus oxygen containing catalyst composition capable of partially oxidizing hydrocarbons (e.g., n-butane) to form a carboxylic anhydride (e.g., maleic anhydride), a process for preparing this catalyst, and a process for using this catalyst to form such anhydrides is disclosed. The catalyst composition is prepared by an organic heterogenous technique followed by a water treatment step and activation.

摘要:The present application relates to the technical field of batteries, and relates to an oxalate material, a preparation method, a use, a lithium-ion battery cathode material and a lithium-ion battery. The oxalate material of the present application comprises the following chemical compositions: Li2TMC4O8, wherein TM is a transition metal having charge of plus two. The oxalate material is a polyanionic-based cathode material having dual electrochemical activities and can be used as a lithium-ion battery cathode active material in a lithium-ion battery. With respect to existing lithium-ion battery cathode materials, the present application provides a designing and preparation method for a cathode material having a good safety and high capability. Besides, the synthesis method for the cathode active material is convenient, rapid and safe and all materials are cheap and easily obtained; and the cathode active material is important for optimizing battery material synthesis technique and reducing electrode material preparation cost.

标题:Hydrocarbon conversion and hydrocracking with layered complex metal silicate and chrysotile compositions
发明人：ROBSON H
权利人:VELSICOL CHEMICAL CORP
摘要:A NEW AND IMPROVED PROCESS FOR THE PREPARATION OF LAYERED COMPLEX METAL SILICATES, ESPECIALLY CHRYSOTILES, AT LOW SEVERITY CONDITIONS. THESE CRYSTALLINE FORM OF COMPLEX METAL SILICATE, FOR SHAPE RANGING FROM THICK WALL TUBES THROUGH THIN WALL TUBES, AND THIN WALL TUBES THROUGH FLAKES, CAN BE PRODUCED, WITH HIGH SURFACE AREA, AS DESIRED, IN HYDRATED FORM, BY CONTACT OF SUITABLE SILICA AND METAL SOURCES IN A REACTION OR SYNTHESIS MIXTURE AT PH OF AT LEAST ABOUT 10, AND PREFERABLY FROM ABOUT 12 TO 14, AT MODERATE TEMPERATURES AND PRESSURES. THE PROCESS CAN PRODUCE CHRYSOTILES, SOME OF WHICH HAVE BE FOUND TO EXIST IN NATURE, OR HETERFORE SYNTHETICALLY PRODUCED, BUT CAN AS WELL PRODUCE CHRYSOLITE SPECIES WHICH DIFFER CHEMICALLY OR PHYSICALLY, OR BOTH, FROM PREVIOUSLY KNOWN SPECIES. NEW AND NOVEL FORMS OF CHRYSOTILE ARE IMPROVED IN MANY OF THEIR PHYSICAL AND CHEMICAL CHARACTERISTICS AS CONTRASTED WITH PREVIOUS SPECIES, AND ARE PARTICULARLY USEFUL DIRECTLY OR INDIRECTLY IN CONDUCTING HYDROCARBON CONVERSION REACTIONS.
