| Abstract | Samples of WO3 supported on γ-Al2O3 with loadings w(WO3) = 1–30 % were prepared by impregnation method and subjected to heat treatment at 500 and 550 °C for 3 h in a static air atmosphere. The catalysts were characterized by TG, DTA, XRD, TEM, TPD-pyridine, and N2 sorption measurements. The surface acidity of the catalysts was investigated by the dehydration of isopropanol and the adsorption of pyridine and 2,6-dimethylpyridine. Catalytic activity and selectivity of the catalysts were investigated for the dehydration of methanol to dimethyl ether at 230 °C in a conventional fixed bed flow type reactor at atmospheric pressure using nitrogen or air as a carrier gas. The results revealed that the catalysts with w(WO3) = 1–5 % loadings, calcined at 500 °C, exhibit a considerable increase in the catalytic performance toward methanol dehydration. The increase was, however, much more pronounced with the catalyst containing w(WO3) = 5 %, which attained dimethyl ether in 89 % yield. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
