Biobutanol is increasingly attracting industrial interest as a fuel additive because of its numerous advantages over bioethanol that include higher calorific value, fuel efficiency, and reduced-engine problems. Therefore, bioethanol valorization to biobutanol provides a good option for the energy industry. This paper reviews literature on the recent progress. for the-ethanol to butane (ETB) process. Issues related to catalyst development and the role of compositional properties (i.e., catalyst nature and acidity-basicity) and reaction parameters in enhancing butanol yield were Critically examined. The mini review also discussed the reaction mechanisms involved and identified new paths for further studies.
