摘要
在工业生产中,助剂Ce的添加对丙烯醛、丙烯酸的产率和选择性都有一定的提高.特别是在选择性上表现得非常好但是丙烷转化率和产物收率却是不高.B1-常规在450℃时丙烷转化率可达到 38.43%,但此时的丙烯醛、丙烯酸的收率分别仅为 5.21%、1.47%.C3-常规的丙烯酸产率最高仅为 10.4%,丙烯醛收率最高的B1-微波也仅为14.75%,可能是比表面积较低等原因,致使催化效果不太理想,但催化剂的结构和文献中催化效果较好的催化剂的结构是比较接近的,只要再改进制备催化剂的方法,可能效果会更好.
Abstract
In industrial production,the addition of additive Ce can improve the yield and selectivity of acrolein and acrylic acid.In particular,the selectivity is very good but the propane conversion and product yield are not high.B1-conventional conversion of propane at 450℃ can reach 38.43%,but the yield of acrolein and acrylic acid is only 5.21%and 1.47%,respectively.The highest yield of C3-conventional acrylic acid is only 10.4%,and the B1-microwave with the highest yield of acrolein is only 14.75%,which may be due to the low specific surface area,resulting in the catalytic effect is not ideal,but the structure of the catalyst is relatively close to that of the catalyst with good catalytic effect in the literature,as long as the method of preparing the catalyst is improved.It might work better.
