摘要：NOVELTY - The preparation process of Ti-Si molecular sieve catalyst includes the following steps: reacting titanium source in alcohol solution and silicon source template agent solution for 3-15 hr and adding water in 3-8 times the silicon source into the reaction product to obtain colloid solution; reacting the colloid solution through heating in non-steady state program control condition to crystallize; filtering, washing, drying and roasting to obtain white solid catalyst powder. The non-steady state program control condition increases the size of the molecular sieve, and this reduces the filtering resistance greatly, eliminates the loss of catalyst, lowers the production cost and reduces the crushing of catalyst during use.
