判断题 吸附效应——直径小于孔径的各种分子均可进入内孔,但分子筛是极性物质,故这些小分子中极性强的优先吸附。水和硫化氢是强极性分子,所以分子筛是干燥气体、脱硫化氢的优良吸附剂。Adsorption effect -- all kinds of molecules with diameter smaller than aperture can enter the inner pore, but molecular sieves are polar substances, so the strong polarity of these small molecules preferential adsorption. Water and hydrogen sulfide are strong polar molecules, so molecular sieve is a good adsorbent for dry gas and hydrogen sulfide removal.
