The invention belongs to the technical field of
air pollution control and particularly relates to high-performance mesoporous-micro double hole controllable
molecular sieve adsorbent and preparation and application thereof. The preparation method includes the following steps that a
silicon source, an
aluminium source, a microporous structure guide agent, a mesoporous template agent, organosilane and water serve as raw materials for synthesizing
mother liquor, the
mother liquor assists into a
hydrothermal reaction through microwaves, a product obtained through the reaction is subjected to
centrifugation,
drying and calcinations, and the high-performance mesoporous-micro double hole controllable
molecular sieve adsorbent is obtained. According to the high-performance mesoporous-micro double hole controllable
molecular sieve adsorbent and preparation and application thereof, an efficient method is utilized for preparing a mesoporous type
zeolite molecular
sieve which is high in specific surface, high in pore volume and high in adsorptive property, the synthesis time is greatly shortened, and the synthesis process is simplified. The synthesized
zeolite type molecular
sieve adsorbent is of a hierarchical pore structure, the
pore diameter is adjustable, the
mass transfer resistance is small, high adsorptive property of VOCs is achieved, high hydrophobic property and hydrothermal stability are achieved, and the high-performance mesoporous-micro double hole controllable molecular
sieve adsorbent has high application value in the field of VOCs
processing technologies.
