Process Design And Economics For The Conversion Of Lignocellulosic Biomass To Hydrocarbon Fuels And Coproducts 2018 Biochemical Design Case Update Biochemical Deconstruction And Conversion Of Biomass To Fuels And Products Via Integrated Biorefinery Pathways

Over the past decade, NREL conducted a campaign to quantify the economic implications associated with observed and future targeted performance for the biochemical conversion of corn stover to ethanol through techno-economic modeling. This report serves as an update to the biological sugar conversion approach, reflecting modifications to underlying conversion operational strategies, as well as refinements to the techno-economic model details. In addition, the report includes a more quantitative focus on envisioned processing requirements for achieving final fuel cost goals moving further into the future, via inclusion of value-added coproducts.

Analytical Methods for Biomass Characterization and Conversion is a thorough resource for researchers, students and professors who investigate the use of biomass for fuels, chemicals and products. Advanced analytical chemistry methods and techniques can now provide detailed compositional and chemical measurements of biomass, biomass conversion process streams, intermediates and products. This volume from the Emerging Issues in Analytical Chemistry series brings together the current knowledge on each of these methods, including spectroscopic methods (Fourier Transform Infrared Spectroscopy, Near-infrared Spectroscopy, Solid State Nuclear Magnetic Resonance), pyrolysis (Gas Chromatography/Mass Spectrometry), Liquid Chromatography/High Performance Liquid Chromatography, Liquid Chromatography/Mass Spectrometry, and so on. Authors David C. Dayton and Thomas D. Foust show how these can be used for measuring biomass composition and for determining the composition of intermediates with regard to subsequent processing for biofuels, bio-chemicals and bio-based products. Covers the broad range of techniques and applications that have been developed and perfected in the last decade Highlights specific analyses required for understanding biomass conversion to select intermediates Provides references to seminal books, review articles and technical articles that go into greater depth, serving as a basis for further study

Plant polyphenols are specialized metabolites that constitute one of the most common and widespread groups of natural products. They are essential plant components for adaptation to the environment and possess a large and diverse range of biological functions that provide many benefits to both plants and humans. Polyphenols, from their structurally simplest forms to their oligo/polymeric versions (i.e. tannins and lignins), are phytoestrogens, plant pigments, antioxidants, and structural components of the plant cell wall. The interactions between tannins and proteins are involved in plant defense against predation, cause astringency in foods and beverages, and affect the nutritional and health properties of human and animal food plants. This eighth volume of the highly regarded Recent Advances in Polyphenol Research series is edited by Juha-Pekka Salminen, Kristiina Wähälä, Victor de Freitas, and Stéphane Quideau, and brings together chapters written by some of the leading experts working in the polyphenol sciences today. Topics covered include: Structure, reactivity and synthesis Bioactivity and bioavailability Metabolomics, targeted analysis and big data Quality control & standardization Biogenesis and functions in plants and ecosystems Biomaterials & applied sciences Distilling the most recent and illuminating data available, this new volume is an invaluable resource for chemists, biochemists, plant scientists, pharmacognosists and pharmacologists, biologists, ecologists, food scientists and nutritionists.

The annual State of Technology (SOT) assessment is a key activity for biochemical platform research. It allows the impact of research progress (both directly achieved in-house at the National Renewable Energy Laboratory [NREL] and indirectly extrapolated from available public data) to be quantified in terms of economic improvements in the overall cellulosic biofuel production process for a particular conversion pathway. As such, initial benchmarks can be established for currently demonstrated performance and progress can be tracked toward out-year goals to ultimately demonstrate cost-competitive biofuel technology. Building upon efforts to progress NREL's biochemical platform R&D work toward ultimate 2030 goals to demonstrate less than $2.50/gallon gasoline equivalent (GGE) fuel selling prices, experimental and techno-economic analysis (TEA) activities have primarily focused on "advanced" biochemical processing strategies to fuels and coproducts, guided by TEA modeling to highlight key barriers and priorities toward achieving this goal across a number of potential bioconversion pathways. The purpose of the present effort is to benchmark the latest experimental developments for these pathways as quantified by modeled minimum fuel selling prices (MFSPs), as a measure of current status relative to those final targets. For this SOT, TEA models were run for two separate biological conversion pathways to fuels, based on available data for integrated biomass deconstruction and hydrolysate processing; namely carboxylic acids (primarily butyric acid) and diols (2,3-butanediol [BDO]), reflecting NREL's recently published 2018 biochemical design report focused on those two pathways. The models were run across two scenarios for lignin utilization, namely combustion and conversion to value-added coproducts.

Rethinking Polyester Polyurethanes: Algae Based Renewable, Sustainable, Biodegradable and Recyclable Materials explains how and why bio-based materials, specifically algae, will change the polymer industry. The book provides background on algae, polyurethanes (PUs), and their everyday use. It covers the biology and chemistry behind how and why these materials are engineered to be both biodegradable and, through the process of depolymerization, fully recyclable. Chapters cover Re-evaluating the Sources, Redefining the Analytics, Reformulating Polyester Polyurethanes, and The Future. The latter part of the book describes the landscape of bio-based materials, the eco-consumer, and insights into the industry problem of “greenwashing. This book is a valuable resource for industry professionals who use polyurethanes in the supply chain for manufactured products, those in sales and marketing or regulatory roles who wish to better understand the unique advantages of bio-based materials, and researchers studying R&D of biobased polyurethanes or remediation of microplastics pollution on land and in bodies of fresh and saltwater worldwide. Builds on the foundation of sustainable, renewable, biodegradable, recyclable microplastics, with lifecycle assessment, techno-economic analysis, and the green premium Clarifies the true economics—if we were to go back to initial development of the plastics industry, what would we do differently? Covers the basic science—the knowledge required to effectively communicate the use of materials that are on first examination more expensive, but on closer examination less expensive when environmental consequences are factored
