1.分子筛催化剂ZSM—5的出现及其在催化研究方面的意义莫比尔公司从50年代开始进行用于催化裂化的分子筛催化剂的开发和工业化研究,发现通过改变分子筛微孔的形状和大小,将它作为催化剂使用时,能显著地改变生成物的选择性。据称,与这些研究相关连,为了增加分子筛的热稳定性及憎水性,开始 1. Molecular sieve catalyst ZSM-5 and its significance in catalytic research Mobile from the 1950s for the catalytic cracking of molecular sieve catalyst development and industrialization study found that by changing the shape and size of molecular sieve micropores, will be When used as a catalyst, it significantly changes the selectivity of the product. Allegedly, associated with these studies, in order to increase the thermal stability and hydrophobicity of molecular sieves,
