Abstract: In this paper, using lithium chloride and calcium chloride as modifying agents, the modified silica gel and molecular sieve composite based on ceramic fiber was prepared by treating ceramic fiber paper with sequential impregnation of the suspension of waterglass and molecular sieve and the aqueous solution of salt. The composition of the modified composite was characterized by using Fourier transform infrared spectroscopy (FTIR). Thermogravimetry (TG) and temperature programmed desorption (TPD) were used to evaluate the desorption performance of the composite. FTIR spectra indicated that impregnation salt has no effect on the composition of molecular sieve. TG and TPD analysis indicated that desorption activated energy of modified composite was lower than that of molecular sieve. The result of the dynamic and static adsorption experiment showed that the adsorption performance of molecular sieve enhanced greatly through the modification. Copyright , Oxford University Press.
