The invention discloses a method for preparing integrated molecular blocks on basis of a 3D printing technology, and belongs to the field of
molecular sieve type adsorbent or catalyst
processing. Themethod comprises the following steps of: (1) uniformly mixing a
molecular sieve body with an inorganic binder, an inorganic
fiber, an organic shaping auxiliary, a pore forming agent and water so as toconfigure a pasty mixture; (2) carrying out ultrasonic treatment on the pasty mixture; (3) designing a printing program; (4) printing
molecular sieve blocks by utilizing a 3D printer; and (5) carrying out low-temperature aging shaping and high-temperature
roasting. According to the method, the 3D printing technology is applied to intelligent preparation of molecular
sieve type bodies for the time, so that the method has the advantages of being simple to operate, low in cost and high in material
utilization rate; and the molecular
sieve blocks have the advantages of being wear-resistant, highin
mechanical strength, developed in pores, uniform in micropore-mesopore-
macropore grade pore structure, small in
pressure reduction and high in
mass transfer rate, and is suitable for
processing various molecular
sieve adsorbents and catalysts.
