Book Description
A comprehensive introduction to the design, synthesis, characterization, and catalytic properties of nanoporous catalysts for the biomass conversion With the specter of peak oil demand looming on the horizon, and mounting concerns over the environmental impact of greenhouse gas emissions, biomass has taken on a prominent role as a sustainable alternative fuel source. One critical aspect of the biomass challenge is the development of novel catalytic materials for effective and controllable biomass conversion. Edited by two scientists recognized internationally for their pioneering work in the field, this book focuses on nanoporous catalysts, the most promising class of catalytic materials for the conversion of biomass into fuel and other products. Although various catalysts have been used in the conversion of biomass-derived feedstocks, nanoporous catalysts exhibit high catalytic activities and/or unique product selectivities due to their large surface area, open nanopores, and highly dispersed active sites. This book covers an array of nanoporous catalysts currently in use for biomass conversion, including resins, metal oxides, carbons, mesoporous silicates, polydivinylbenzene, and zeolites. The authors summarize the design, synthesis, characterization and catalytic properties of these nanoporous catalysts for biomass conversions, discussing the features of these catalysts and considering future opportunities for developing more efficient catalysts. Topics covered include: Resins for biomass conversion Supported metal oxides/sulfides for biomass oxidation and hydrogenation Nanoporous metal oxides Ordered mesoporous silica-based catalysts Sulfonated carbon catalysts Porous polydivinylbenzene Aluminosilicate zeolites for bio-oil upgrading Rice straw Hydrogenation for sugar conversion Lignin depolymerization Timely, authoritative, and comprehensive, Nanoporous Catalysts for Biomass Conversion is a valuable working resource for academic researchers, industrial scientists and graduate students working in the fields of biomass conversion, catalysis, materials science, green and sustainable chemistry, and chemical/process engineering.

Book Description
Growing environmental concerns associated with diminishing reserves of fossil fuels has led to accelerated research efforts towards the discovery of new catalytic processes for converting renewable lignocellulosic biomass into value-added chemicals. For this conversion, nanoporous solid acid materials have been widely used because of their excellent hydrothermal stability and molecular sieving capability. In the thesis, hierarchical Lewis acid zeolites with ordered mesoporosity and MFI topology (three dimensionally ordered mesoporous imprinted (3DOm-i) Sn-MFI) were successfully synthesized within the confined space of three dimensionally ordered mesoporous (3DOm) carbon by a seeded growth method. The obtained 3DOm-i Sn-MFI showed at least 3 times higher catalytic activities for the biomass-derived sugar isomerization than conventional Sn-MFI zeolites. This is because the mesopores in the hierarchical zeolites greatly enhance molecular transport. In addition, Lewis acid Sn-MFI combined with Pt metal nanoparticles (Pt/Sn-MFI) could oxidize glycerol to produce lactic acid (LA) under base-free conditions. Glycerol is a by-product in biodiesel synthesis. 80.5% selectivity of LA was achieved at 89.8% conversion of glycerol using a bifunctional Pt/Sn-MFI catalyst under base-free conditions. In the tandem reaction pathway, selective oxidation of glycerol to glyceraldehyde (GLA) and dihydroxyacetone (DHA) by using Pt catalysts was cascaded with Lewis acid catalyzed isomerization of GLA/DHA into LA. Moreover, morphology-tunable Lewis acid Sn-BEA with hydrophobicity was successfully synthesized by recrystallization of post-synthesized Sn-BEA (Sn-BEA-PS) using ammonium fluoride (NH4F) and tetraethylammonium bromide (TEABr). This recrystallization includes simultaneous procedures of dissolution-reassembly: i) the dissolution of Si-O bonds around silanol nests by fluoride ions, and ii) the reassembly of fragmented silica species into defect-free zeolite framework in the presence of TEA ions. The recrystallization also increased open Lewis acid Sn sites. These findings can explain why a 2.5 times higher rate of aqueous glucose isomerization was achieved on recrystallized Sn-BEA (Sn-BEA-RC), compared with Sn-BEA-PS. Moreover, in the isomerization of bulky lactose (C12 sugar) dissolved in MeOH, hierarchical Sn-BEA-RC showed a 3.2-fold higher activity than hydrothermally synthesized Sn-BEA (Sn-BEA-HF), due to the mesopores and enhanced organophobic character of the recrystallized catalyst. In the final part, renewable p-xylene synthesis was investigated. p-Xylene is a major commodity chemical used for the production of polyethylene terephthalate (PET) with applications in polyester fibers, films and bottles. Diels-Alder cycloaddition of 2,5-dimethylfuran (DMF) and ethylene with subsequent dehydration of the cycloadduct intermediate to produce p-xylene is an attractive reaction pathway for its production from biomass feedstocks. It was shown that phosphorous-containing zeolite BEA (P-BEA) is active, stable and selective for this reaction with an unprecedented p-xylene yield of 97%. It can selectively catalyze the dehydration reaction from the furan-ethylene cycloadduct to p-xylene, without performing side reactions which include alkylation and oligomerization. This acid catalyst establishes a commercially attractive process for renewable p-xylene production.

Book Description
Biorefineries are becoming increasingly important in providing sustainable routes for chemical industry processes. The establishment of bio-economic models, based on biorefineries for the creation of innovative products with high added value, such as biochemicals and bioplastics, allows the development of “green chemistry” methods in synergy with traditional chemistry. This reduces the heavy dependence on imports and assists the development of economically and environmentally sustainable production processes, that accommodate the huge investments, research and innovation efforts. This book explores the most effective or promising catalytic processes for the conversion of biobased components into high added value products, as platform chemicals and intermediates. With a focus on heterogeneous catalysis, this book is ideal for researchers working in catalysis and in green chemistry.

Book Description
This volume looks at modern approaches to catalysis and reviews the extensive literature. Chapters highlight application of 2D materials in biomass conversion catalysis, plasmonic photocatalysis, catalytic demonstration of mesoporosity in the hierarchical zeolite and the effect of surface phase oxides on supported metals and catalysis. Looking to the future a chapter on ab initio machine learning for accelerating catalytic materials discovery is included. Appealing broadly to researchers in academia and industry, these illustrative chapters bridge the gap from academic studies in the laboratory to practical applications in industry not only for catalysis field but also for environmental protection. Other chapters with an industrial perspective include heterogeneous and homogeneous catalytic routes for vinyl acetate synthesis, catalysis for production of jet fuel from renewable sources by HDO/HDC and microwave-assisted catalysis for fuel conversion. Chemical reactions in ball mills is also explored. The book will be of great benefit to any researcher wanting a succinct reference on developments in this area now and looking to the future.
