【摘要】 综述了吸附法深度脱除燃料油中硫化物的吸附机理及技术进展,主要包括物理吸附脱硫、反应吸附脱硫和选择性吸附脱硫的研究进展。物理吸附脱硫技术对硫化物的选择性较差且很难实现深度脱硫,而反应吸附脱硫在高温下才能有较好的吸附性能,吸附剂的再生温度较高。选择性吸附脱硫技术最具发展前景,操作条件温和,投资和操作费用低,能深度脱硫,是近期最有希望实现零硫目标的脱硫技术,但吸附剂对含硫化合物的选择性和硫含量还有待进一步提高。更多还原

【Abstract】 Based on the mechanism of adsorption,this paper reviews physical adsorptive desulfurization,reactive adsorptive desulfurization and selective adsorptive desulfurization.Physical adsorptive desulfurization is not expected to be very selective for sulfur compounds in transportation fuels and deep removal of sulfur cannot be realized.Reactive adsorptive desulfurization can achieve high sulfur-adsorption capacity when adsorption temperature is high,but the adsorbent regeneration temperature is very high.Selective adsorptive desulfurization is considered to be more promising,because of low investment,low operation cost and high desulfurization efficiency.It is the most promising process to reach the “zero sulfur” objective in the near future,but sulfur capacity of adsorbents and their selectivity for sulfur compounds could not yet satisfy the requirement in industrial application.更多还原
