Based on analysis of problems existed in application of inertial vibrosieve,the new type variable frequency hydraulic straight-vibrating sieve is introduced.
Mesoporous molecular sieves are of great academic and practical importance in heterocatalysis. In this review, we mainly summarized the progress made in its catalytic application.
According to the shape of screening impurities to choose hole-shaped sieve plate(move out long, Diamond impurities) and the slit-shaped sieve plate(move out particles shape impurities and emplastic).
According to the shape of screening impurities to shoose hole-shaped sieve plate (move out long ,Diamond impurities)and the slit-shaped sieve plate (move out particles shape impurities and emplastic).
