This article emphatcaiily explores the way to increase the gas-carrying effect of zeoliterock bymeans of ypemodification treatment.In the experiment,six different kinds of zeolite rock with two sizes each(1.2-0.6mm,0.6-0.3mm)were used as the samples.The reagents used here included HCl(1.5N),NH_4Cl(0.7N)andthe mixture of HCl(1.5N)and NH_4Cl(0.75N).The samples were heated by a circulation conden-ser so as to be changed into 3 new types,type H~+,type NH_4~+and mixed type.The experimental re-sults showed that boiling HCl is the most effective for increasing the amount of gas produced,the less effective is soaking in the mixture and the worst is soaking in NH_4Cl.In the first 5minutes after Changing in type,zeolite rock had the maximum gas-producing speed,and at theend of 48 hours it kept on producing gases,though slowly.The optimum dehydration tempera-ure of zeolite rock ranges usually from 500℃ to 300℃,at which zeolite rock produces gas at themaximum speed,while at 200℃ it produces gas at the minimum speed.From he experimentalresults with XRD and DTA it follows tha after changing in type the purity of zeolite is inc-eased and because of its super-porosity effect the amounyt of gas produced is increased too.
This article emphatcaiily explores the way to increase the gas-carrying effect of zeoliterock bymeans of ypemodification treatment. The experiment, the six different kinds of zeolite rock with two sizes each (1.2-0.6mm, 0.6-0.3mm) were used as the samples The reagents used here included HCl (1.5N), NH 4 Cl (0.7N) and the mixture of HCl (1.5N) and NH 4 Cl (0.75N). The samples were heated by a circulant-ser so as to be changed into 3 new types, type H ~ +, type NH_4 ~ + and mixed type. the experimental re-sults showed that boiling HCl is the most effective for increasing the amount of gas produced, the less effective is soaking in the mixture and the worst is soaking in NH 4 Cl. In the first 5 minutes after Changing in type, zeolite rock had the maximum gas-producing speed, and at the end of 48 hours it kept on producing gases, though slowly. Temperatures of zeolite rock usually from 500 ° C at 300 ℃, at which zeolite rock produces gas at the maximum speed, while at 200 ℃ it produces gas at the minimum speed. Frohe experimental results with XRD and DTA it follows tha after changing in type the purity of zeolite is inc-eased and because of its super-porosity effect the amounyt of gas produced is increased too.
