| 英文摘要 | cs(2) removal was obtained by coupling catalytic hyidation on bi-functional catalyst. on the hydrolysis active sites, cs(2) is hydrolyzed to h(2)s, while on the oxidation active sites, h(2)s is oxidized to elemental s or sulfuric acid deposited on the porous support. the above can be expressed as follows: cs(2) (h(2)o) under right arrow cos (h(2)o) under right arrow h(2)s (o(2)) under right arrow s/so(4)(2-). h(2)s oxidation eliminates its prohibition on cs(2) hydrolysis so that the rate of coupling removal cs(2) is 5 times higher than that of cs(2) hydrolysis. the same active energy of hydrolysis and coupling reaction also indicates that h(2)s oxidation does not change the reaction mechanism of cs2 hydrolysis. temperature has obvious effect on the process while the mole ratio of o(2) concentration to cs(2) concentration (o/s) does not, especially in excess of 2.5. the formation of sulfuric acid on the catalyst surface poisons hydrolysis active sites and causes the decrease of left oh(-1) concentration on the catalysts surface. lower temperature is suggested for this bi-functional catalyst owing to the low yield ratio of s/so(4)(2-). |
