| Abstract | The acid-catalyzed conversion of lignocellulosic biomass (AC3B) process has been developed for the direct liquefaction of lignocellulosic biomass. In the original version, the main products, ethyl esters, are produced in acidic medium containing ethanol, using a one-pot conversion system. Our research strategy for obtaining a high overall performance is based on two general concepts: (a) coupling of catalytic/chemical reactions that lead to desired products and (b) decoupling of reactions that produce unwanted products, by decreasing the effectiveness of these reactions. Concept (a) is realized by using oxidizers (hydrogen peroxide and Fenton’s reagent) that promote a higher production of carboxylic acids as main intermediates, while concept (b) contributes to a significant decrease of undesired formation of polymeric products. As result of these reaction coupling and decoupling, the overall yield of liquid products has been multiplied by a factor of 2.5 (from 27 to over 70 wt%). Not only the yields of products from cellulose and hemicellulose components experience considerable increases, but also the lignin component starts undergoing a noticeable conversion. Essentially, the AC3B process, in the most recent version, consumes ethanol that is partly used to produce liquid fuels and chemicals from lignocellulosic biomass. The other amount of feed ethanol is converted—via diethyl ether and over ZSM-5-based catalysts—into aromatics-rich gasoline and liquefied petroleum gas—grade hydrocarbons.Sequence of actions that have significantly improved the total product yield (RP): AC = acidic medium, HP = addition of hydrogen peroxide, DL-st = use of a delignification step, FR = use of a Fenton-type reagent, PIn = use of a polymerization inhibitor |

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.
