Summary, etc. A series of solid acid catalysts like CeO<sub>2</sub>, CeO<sub>2</sub>-ZrO<sub>2 </sub>and SO<sub>4</sub><sup>-2</sup>/CeO<sub>2</sub>-ZrO<sub>2 </sub>have been coated over monoliths by dip and dry process. Catalysts have been characterized by NH<sub>3</sub>-TPD for surface acidity, PXRD for crystallinity, FT-IR analysis for functionality, SEM and TEM for morphology. The catalytic activity of the synthesized materials is trialled by liquid-phase esterification of acetic acid with butanol. The catalytic activity is correlated with acid sites examined by NH<sub>3</sub>-TPD method. Optimization of reaction is carried out by altering the molar ratio, temperature, catalyst nature and time of the reaction. A detailed techno-economical analysis of the catalytic material and the procedure followed for the esterification reaction is also studied. In the techno-economical analysis, it is noticed that microwave assisted heating is more advantageous over conventional one. In case of microwave heating, the conversion of BA is 98% with a shorter reaction time of 12 min but in the case of conventional method of heating, it takes almost 6 h to get the above said conversion. It is further noticed that a comparative analysis of honeycomb over powder forms clearly states that, honeycomb forms shows almost 4 fold time increase in the conversion of BA compared to their powder analogs.
