石脑油用吸附脱硫分子筛的改性研究进展

Progress on modification of adsorption and desulfurization molecular sieves for naphtha

介绍了石脑油脱硫所用吸附脱硫分子筛的特点,综述了分子筛吸附剂的改性方法,包括单金属改性、双金属改性、酸改性以及碱改性等,并对石脑油吸附脱硫技术的研究提出发展建议,指出今后仍然以提高分子筛的硫容和选择性为主。

The characteristics of adsorption desulfurization molecular sieves used in naphtha desulfurization were introduced,the modification methods of molecular sieve adsorbents were reviewed,including monometallic modification,bimetallic modification,acid modification and alkali modification with 40 references.And the development suggestions were put forward for the research of naphtha adsorption desulfurization technology,which would still be focusing on improving the sulfur capacity and selectivity of molecular sieves in the future.
