Patent number: 7510659Abstract: Present invention deals with cost-effective surface-modified zeolite materials developed from commercial zeolites and flyash-based zeolites by treating with surface modifiers like hexadecyltrimethyl ammonium bromide (HDTMA-Br). The formation of zeolitic materials with anionic characteristics requires treatment with a surfactant with initial concentrations greater than its critical micelle concentration (CMC). The sorption of oxyanions on the surfactant-modified zeolite (SMZ) is attributed to surface complexation and surface precipitation. Incorporation of metal ions on SMZ showed improved anion uptake for dearsenification of water due to synergistic effects and is able to meet the stringent target of 10 ppb of As on potable water being adopted by most countries. High selectivity, faster kinetics and high adsorption capacity ensures cost effectiveness of this product as compared to other low-cost products for dearsenification.Type: GrantFiled: August 23, 2006Date of Patent: March 31, 2009Assignee: Council of Scientific & Industrial ResearchInventors: Sadhana Suresh Rayalu, Pawan Kumar, Siddharth Ulhas Meshram, Amit Kumar Bansiwal, Nitin Kumar Labhsetwar, Rishi Narayan Singh, Sukumar Devotta

Patent number: 7494951Abstract: The present invention relates to a process for the manufacture of catalysts used for producing para-xylene by toluene shape selective alkylation. The invention is primarily used for solving the problems in the old technology, e.g., high requirements on the environment and great treatment of waste water containing organic amines when synthesizing ZSM-5 molecular sieves by using an organic amine as the template agent; small and non-homogeneous particles of the molecular sieves when synthesizing ZSM-5 molecular sieves by using an alcohol or ether as the template agent, such that the catalyst prepared thereby has low catalytic selectivity and low toluene conversion rate, etc. Said problems are better solved in the present invention by synthesizing ZSM-5 molecular sieves using the combination of organic amines and alcohols or ethers as the template agents (having a weight ratio of organic amines/alcohols=0.05-150, and organic amines/ethers=0.05-150), and modifying with organosilicon so as to obtain the catalysts.Type: GrantFiled: August 14, 2006Date of Patent: February 24, 2009Assignees: China Petroleum & Chemical Corporation, Shanghai Research Institute of Petrochemical Technology SinopecInventors: Zhirong Zhu, Dejin Kong, Weimin Yang, Qingling Chen, Wei Zou, Wei Li, Min Hou, Deqin Yang
