That molecular sieve AlPO_4 absorbs water vapor does hot change their basic chemical structure, and the adsorption process is reversible. AlPO4分子筛吸附水汽并没有改变其基本的化学结构,此吸附过程是可逆的。
In this paper, a safe and effective oxygen removal and methane enrichment process is proposed which is based on vapor pressure swing adsorption ( VPSA). 本文提出了一种安全有效的从煤层气中分离氧气和富集甲烷的变压吸附流程,并建立了实验室规模的两塔真空变压吸附(VaporPressureSwingAdsorption,VPSA)装置。
