| Abstract | Methanation of residual syngas as a downstream process after liquefied petroleum gas (LPG) synthesis is considered to be an attractive alternative to conventional gas separation. Seven intensively studied factors in catalyst development (ratio of Fe/Ni, metal loading, selection of Al2O3 or SiO2 as oxidic support, addition of promoters such as potassium and/or MgO, heat dissipation by diluting with inert material and two common preparation techniques (impregnation and precipitation)) were selected within a Plackett–Burman screening design and rated towards their impact on catalytic performance such as carbon monoxide and hydrocarbon conversion as well as methane and carbon dioxide selectivity. Detailed characterization of fresh and used catalysts has been carried out applying N2-physisorption, X-ray diffraction (XRD), inductively coupled plasma atomic emission spectroscopy (ICP-AES), temperature-programmed reduction (H2-TPR), and transmission electron microscopy with energy-dispersive spectroscopy (TEM/EDS) in order to confirm the results. Finally, suggestions on the preferred levels of these factors are made for development of advanced catalysts. |

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.
