This book outlines the most recent progress in the development of technologies for carbon dioxide utilization into renewable synthetic fuels and platform chemicals via chemical and biological routes. Various processes are discussed, including thermocatalytic, electrocatalytic, phoatalytic, and biological conversion. This SpringerBrief consists of four chapters, each chapter outlining fundamentals and catalytic mechanisms, and discussing main design considerations and major technological challenges, providing also a brief outline of the most recent progress. The book is useful for a broad community of academic and industrial researchers in the fields of chemical reaction engineering, electro- and photo-chemistry, and biochemical engineering, with specific emphasizes on heterogeneous catalysis, reactor design and process development.
