▎ 摘  要

NOVELTY - Preparing composite A-type molecular sieve raw powder containing wave-absorbing material comprises adding the microwave-absorbing material powder of micro-nano size, placing in the A-type molecular sieve precursor reaction solution, after microwave heating to react, in the microwave heating process, selectively heating the wave absorbing material under the effect of particle surface effect, as molecular sieve growth of seed crystal in-situ growing synthetic A type molecular sieve, the synthetic A type molecular sieve coated wave absorbing material, after the reaction, and drying. USE - The composite A-type molecular sieve raw powder containing wave-absorbing material is used as adsorbent in removing impurity (claimed). ADVANTAGE - The wave-absorbing material: can deeply absorb specific molecule, and rapidly regenerated by microwave heating. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) composite A-type molecular sieve raw powder containing wave-absorbing material, prepared by the preparation method comprising a micro-nano-sizedwave-absorbing material, and A-type molecular sieve obtained by in-situ growing the micro-nano-sized wave-absorbing material as seed crystal and A-type molecular sieve coated wave-absorbing material; and (2) full zeolite molecular sieve containing wave-absorbing material, is prepared by the preparation method, the grain diameter distribution of the full zeolite molecular sieve containing wave-absorbing material is 0.1-5 mm, the ion exchange degree in the process is not greater than 95%, the static water absorption is not greater than 20 wt.%, the water content is not greater than 1.5 wt.%, the wear rate is less than 1.5 wt.%.
