Biodiesel Production with Green Technologies

By: Aminul Islam,Pogaku Ravindra

This book provides a single-source reference to green technologies in advanced biofuel technology. The main focus is on the description of the state of the art in catalytic processes for the "green" production of biofuels. The authors describe two different, practical approaches for catalysts, which allow for effective and easy separation of the catalyst by simple filtration, and enable reuse for several cycles. Readers will gain understanding as to the mechanisms involved in the synthesis and structure formation of the catalyst, in order to maximize yield of biodiesel production. The authors also address the question of how catalytic material should be distributed inside a porous support to obtain optimal performance. The effects of physicochemical and operating parameters are analyzed to gain insight into the underlying phenomena governing the performance of optimally designed catalysts.“br>

Production of biodiesel using lipase encapsulated in κ-carrageenan

By: Pogaku Ravindra,Kenthorai Raman Jegannathan

This book explores a novel technique for processing biodiesel using lipase immobilization by encapsulation and its physical properties, stability characteristics, and application in stirred tank and re-circulated packed bed immobilized reactors for biodiesel production. The enzymatic processing of biodiesel addresses many of the problems associated with chemical processing. It requires only moderate operating conditions and yields a high-quality product with a high level of conversion and the life cycle assessment of enzymatic biodiesel production has more favourable environmental consequences. The chemical processing problems of waste water treatment are lessened and soap formation is not an issue, meaning that waste oil with higher FFA can be used as the feedstock. The by product glycerol does not require any purification and it can be sold at higher price. However, soluble enzymatic processing is not perfect. It is costly, the enzyme cannot be recycled and its removal from the product is difficult. For these reasons, immobilized enzymatic process has been developed which retains the advantages of the soluble enzymatic process and reuse of the enzyme is possible which decreases the enzyme cost, the biodiesel produced does not contain any enzyme residue and the activity of the enzyme can be increased by immobilization. The drawbacks of the immobilized enzyme process are mass transfer limitation, enzyme leakage, the lack of a versatile commercial immobilized enzyme and some of immobilization methods involve toxic chemicals. To overcome the drawbacks of the immobilized enzyme, an attempt is made to use a degradable biopolymer (κ-carrageenan) as a carrier for lipase immobilization.

Teasers of Chemical Engineering and Technology

By: Ravindra Pogaku

This book has been written in view of the dire necessity of students and practising professionals of chemical engineering. The questions are innovative in their own way. The users would find it very handy in taking competitive exams, attending interviews and a ready-guide to practising professionals. This book covers most of the areas of chemical engineering, and other allied areas. Most normal textbooks used by chemical engineering, food engineering and biochemical engineering students are lack in adequate multiple-choice questions. For a better understanding of the subject, analytical ability and reasoning are key factors. Hence, this teasers of chemical engineering book would be beneficial to readers.

Advances in Biofuels

By: Pogaku Ravindra,Rosalam Hj. Sarbatly

Biofuels will play a key role in the 21st century as the world faces two critical problems; volatile fuel prices and global climatic changes. Both of these are linked to the overdependence on the fossil fuels: petroleum, natural gas, and coal. Transportation is almost totally dependent on petroleum based fuels such as gasoline, diesel fuel, liquefied petroleum gas, and on natural gas. Despite a significant amount of research into biofuels, the field has not been able to replace fossil fuels. Recent advances will change this scenario. Extracting fuel from biomass has been very expensive (both monetarily and in land usage), time consuming, unusable byproducts, etc. Technology to obtain liquid fuel from non-fossil sources must be improved to be faster, more efficient and more cost-effective. This book will cover the current technology used for a variety of plant types and explore shortcomings with each.
