  • What is 4A zeolite?
  • 4A zeolite, whose ideal chemical structure formula is Na 12 [ (AlO 2) 12 (SiO 2) 12 ]·27H 2 O, is a type of crystalline aluminium-containing silicate with homogeneous microchannels ( García et al., 2015; Shen et al., 2017 ).
  • How was 4A zeolite synthesized based on hydrothermal method?
  • 4A zeolite was synthesized based on hydrothermal method by using OWR of palygorskite mine from Xuyi County, Jiangsu Province, China. Natural OWR underwent extrusion, crushing, and screening to obtain OWR particles of 200 mesh (0.075 mm).
  • Can 4A zeolite be synthesised from Owr?
  • As it is known, a study about the synthesis of 4A zeolite from OWR has not been reported. This work provides a new material for synthesis of 4A zeolite and a new method for the removal of ammonium ion. Importantly, a novel method to utilize OWR producing during palygorskite mine exploitation was achieved.
  • Which zeolite is best for CO2 adsorption?
  • Zeolite 4A 15, zeolite 13X 16, ZK-5 17, ZSM-5 18, β-zeolite 19, and Na-X 20 are among the zeolite types that have demonstrated potential in applications related to CO 2 capture. These zeolites possess distinctive pore structures, substantial surface areas, and excellent thermal stability, rendering them highly desirable options for CO 2 adsorption.
