This book investigates the development of sorption enhanced reaction processes (SERPs) with detailed modelling and simulation, design and operation of units. SERPs are processes intensified by combining adsorption and reaction, reaction and membranes or reaction/adsorption/membranes in a single unit in order to overcome thermodynamic limitations of conversion in reversible reactions. The focus here is on gas phase and liquid phase processes involving different technologies, including pressure swing adsorptive reactors, membrane reactors and simulated moving bed reactors. Emphasis is also given to presenting data and practical applications of SERP products.Sorption Enhanced Reaction Processes provides undergraduate and graduate students of chemistry and chemical engineering, researchers and industrial engineers with a clear path towards process development of SERP, whatever the area of application.
Lignin is one of the most abundant plant-derived feedstock on earth and qualifies as a renewable material. However, lignin is widely recognized as waste byproduct of the cellulosic ethanol and pulp and paper industry. How to properly modify lignin and develop it into functional polymers is a huge challenge, but an attractive research topic in both industry and academia.This book brings together leading engineering approaches to address the challenges of lignin valorization. It presents the chemistry and properties of different types of lignin, and explores the cutting-edge approaches of lignin modifications. Unlike any existing texts, this book not only summarizes the traditional ways of using lignin, but also presents various potential applications of lignin materials together with advanced processing techniques.The basis of lignin (its chemistry, types and properties) is described, as are different approaches to modify it. The features of lignin and its copolymers are explored and aligned with their potential applications. In addition to the carbon materials from lignin, the advanced fabrication approaches to engineer lignin-based micro/nano-structural materials are summarized.
There is a wide consensus that furfural, a renewable commodity currently obtained from lignocellulosic agro-residues with a production volume of around 300 kTon per year, is a key feedstock for leveraging lignocellulosic residues in future biorefineries. Several chemicals are already being manufactured from furfural due to its advantageous production cost. Furthermore, a vast number of others are also technically viable, to produce from oil.This book compiles the vast existing information into relevant stages of transformations of furfural as renewable chemicals, biofuels and bioresins focusing on the relevant chemical and engineering aspects of processes to obtain them, including reactors and catalysis. It offers essential information for improving the economic and environmental viability of current commercial applications and upcoming future applications.It should be of particular interests to graduate and advanced undergraduate students, as well as, engineers and academic researchers alike who are working in the field.
Light alkanes tend to be resistant to many forms of activation. The horizontal approach of the present book covers homogeneous, heterogeneous and biological catalysis, thus allowing readers to gain an awareness of progress and ideas in research areas different from their own. The book contains both general chapters, giving an overview of the subject, and specialised contributions that deal with the details and state of the art. A specialist report is also included which gives a critical insight into current progress and discusses future prospects and major challenges. Audience: Newcomers and senior researchers in the field of alkane activation. The mixed theoretical and practical approach will be of interest to researchers and industrialists alike.
This book constitutes the refereed proceedings of the Third Latin-American Symposium on Dependable Computing, LADC 2007, held in Morelia, Mexico, in September 2007. The papers are organized in topical sections on fault-tolerant algorithms, software engineering of dependable systems, networking and mobile computing, experimental dependability evaluation, as well as intrusion tolerance and security.
The term 'green chemistry' was coined by Anastas and Warner in the early 1990s and it is nowadays the mainstay of designing and implementing advanced chemical processes that decrease or eliminate the use and generation of hazardous substances whilst minimizing energy consumption.Solution Combustion Synthesis of Nanostructured Solid Catalysts for Sustainable Chemistry is an interdisciplinary collection of fundamental and applied cutting-edge studies which highlight general and specific aspects of the synthesis of nanostructured catalysts through Solution Combustion Synthesis (SCS), studying their applications from the perspective of green chemistry.This book intends to integrate the fundamental principles of the SCS process with its engineering aspects and covers the synthesis of a wide variety of catalytic materials. This reference book can be used as a permanent consulting material for students, researchers and the general readership for green chemistry, nanochemistry, materials science and chemical engineering.
High throughput experimentation has met great success in drug design but it has, so far, been scarcely used in the field ofcatalysis. We present in this book the outcome of a NATO ASI meeting that was held in Vilamoura, Portugal, between July 15 and 28, 2001, with the objective of delineating and consolidating the principles and methods underpinning accelerated catalyst design, evaluation, and development. There is a need to make the underlying principles of this new methodology more widely understood and to make it available in a coherent and integrated format. The latter objective is particularly important to the young scientists who will constitute the new catalysis researchers generation...
This book constitutes the refereed proceedings of the 16th Portuguese Conference on Artificial Intelligence, EPIA 2013, held in Angra do Heroísmo, Azores, Portugal, in September 2013. The 45 revised full papers presented were carefully reviewed and selected from a total of 157 submissions. The papers are organized in the following topical sections: ambient intelligence and affective environments; artificial intelligence in transportation systems; artificial life and evolutionary algorithms; computational methods in bioinformatics and systems biology; general artificial intelligence; intelligent robotics; knowledge discovery and business intelligence; multi-agent systems: theory and applications; social simulation and modeling; and text mining and applications.
This study analyzes the establishment of an iron foundry in the interior 18th-century of Angola. It was a fruit of the Portuguese Enlightenment, which encouraged investment in manufacturing, particularly of iron, a metal indispensable for military and technological purposes. However, the plans faced the resistance of African blacksmiths and founders who refused to learn foreign techniques and work processes. By emphasizing Central African agency, the book highlights the successful strategies of historical actors who scholars have largely ignored. Based upon a wide variety of sources from Brazilian, Portuguese, and Angolan archives, the book reconstructs how Africans were taken to work at the...
