A series of solid acid catalysts like CeO₂, CeO₂-ZrO₂ and SO₄^-2/CeO₂-ZrO₂ have been coated over monoliths by dip and dry process. Catalysts have been characterized by NH₃-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 NH₃-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.

修饰形式二氧化铈包覆的堇青石蜂窝状整体料，用于微波辐射酸催化合成乙酸丁酯

通过浸渍和干燥工艺将一系列固体酸催化剂如CeO ₂，CeO ₂ -ZrO ₂和SO ₄ ^-2 / CeO ₂ -ZrO ₂涂覆在整料上。催化剂的特征在于表面酸性为NH ₃ -TPD，结晶度为PXRD，功能为FT-IR分析，形态为SEM和TEM。通过乙酸与丁醇的液相酯化试验了合成材料的催化活性。催化活性与NH ₃检测到的酸位相关-TPD方法。通过改变摩尔比，温度，催化剂性质和反应时间来进行反应的优化。还研究了催化材料的详细技术经济分析和酯化反应遵循的程序。在技​​术经济分析中，注意到微波辅助加热比常规加热更有利。在微波加热的情况下，BA的转化率为98％，而反应时间为12分钟，但是在常规加热方法的情况下，几乎需要6小时才能获得上述转化率。还应注意，对粉末形式的蜂窝进行比较分析清楚地表明，与粉末类似物相比，蜂窝形式显示出BA转化率几乎提高了4倍。
