The research is intended to synthesize zeolite from Silica sol H-ZSM-5 – (30% colloidal silica, LUDOX HS-30 wt SiO2) as the silica source on synthesis by studying the effect of the various variables of H-ZSM-5 zeolite synthesis include the temperature at 60, 90, 110, 130° c ratio is 20:1, by studying the physical characteristics and the duration used in the process of hydraulic thoeman. Trial found that dementia is the appropriate synthesis zeolite H-ZSM-5 is temperature 90° c duration 15 days after reacting zeolite crystallization powder, coarse and are arranging is clearly Crystal by XRD pattern has appeared near position occurred in the range Sc.Ale 8-10 and 20-25 p in the same position, outstandingly well-suited to your H-ZSM-5 and proportions of Si/Al is the tendency of inserting more and constant at 1%: 7: where the duration and temperature affect the reactivity of the H-ZSM-5 that is associated with the energy crystals in stimulating synthesis.
