Green Urea

This book presents a game changing technology of lower energy-intensive urea production of urea which is used as fertilizer. The technology, from a resource to a knowledge-intensive based industry, investigates a new synthesis approach employing electromagnetic induction and nano-catalyst at lower energy consumption. This clean and green method for a sustainable future might change the landscape of future chemical processes. It is made possible due to the enhancement in nanotechnology where quantum mechanical understanding is called into play. New reactor designs are elaborated on and discussed explicitly. Hematite and nickel oxide nanocatalysts are proposed for the green urea synthesis process, in the presence of static and oscillating magnetic fields. Strategies to increase single to triplet conversion rate are given for better understanding of the improved urea rate. The focus is deliberately on scrutinizing the greenhouse gas effect on the urea yield, in this case CO2 flow rate. Coating techniques for slow release strategies are provided to reduce the volatilization of ammonia and leaching effect, hence offering a complete solution of Green Technology. Agriculture 4.0 that creates the new patterns and precision monitoring of crop rotation and livestock utilization will be able to pave the way for better crop yield. Development of advanced technology in agriculture is important for the implementation of Agriculture 4.0 and currently an inevitable trend of the socioeconomic development in the context of broader international integration for the sustainable future. The author would like to acknowledge Ministry of Higher Education (MOHE) for the grant worth RM 12 million to accomplish Green and Economical Urea project and to have full understanding on Green Technology in Urea. This book is a collaborative effort by her colleagues, Ku Zilati, Khanif, Shahrina, Zainovia, Azizah, Zakaria, and who have carried out the research over the past five years which started in 2011. Their unconditional commitment had brought us together and we completed the project with success. I wish to also thank Dr Menaka Ganeson and all my PhD students, Dr. Saima, Dr. Bilal, Mr. Zia and Mr. Irfan for their commitment to assist me to complete the book. Last but not least, thank you very much to Professor Mike Payne (Cambridge University) and Professor Koziol (Cranfield University) for the comments.

Interdisciplinary approach to sustainability, illustrating current catalytic approaches in applied chemistry, chemical engineering, and materials science Catalysis for a Sustainable Environment covers the use of catalysis in its various approaches, including homogeneous, supported, and heterogeneous catalysis, and photo- and electrocatalysis, towards sustainable environmental benefits. The text fosters interdisciplinarity in sustainability by illustrating modern perspectives in catalysis, from fields including inorganic, organic, organometallic, bioinorganic, pharmacological, and analytical chemistry, along with chemical engineering and materials science. The chapters are grouped in seven sections on (i) Carbon Dioxide Utilization, (ii) Volatile Organic Compounds (VOCs) Transformation, (iii) Carbon-based Catalysis, (iv) Coordination, Inorganic, and Bioinspired Catalysis, (v) Organocatalysis, (vi) Catalysis for Water and Liquid Fuels Purification, and (vii) Hydrogen Formation/Storage. Sample topics covered in Catalysis for a Sustainable Environment include: Activation of relevant small molecules with strong environmental impact and carbon-based catalysts for sustainable chemical processes Catalytic synthesis of important added value organic compounds, in both commodity and fine chemistries (large and small scale productions, respectively) Development of catalytic systems operating under environmentally benign and mild conditions towards the establishment of sustainable energy processes Catalysis by coordination, metal and metal-free compounds, MOFs (metal-organic frameworks) and nanoparticles, and their contribution to environmental and sustainable processes Employing the latest approaches that impact global and circular economies, Catalysis for a Sustainable Environment serves as an excellent starting point for innovative catalytic approaches, and will appeal to professionals in engineering, academia, and industry who wish to improve existing processes and materials.

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.
