摘要

COS水解催化在工业气净化脱硫中具有重要意义。镁铝类水滑石基氧化物（MgAl-MMO）在简单气氛（COS + H

O）下可有效催化COS水解，然而O

S对MgAl-MMO的催化影响作用尚不明晰，同时现有催化剂合成方法耗时较长。探索了微波辅助合成MgAl-MMO的可行性，并研究了其在反应气含O

S下的催化行为。结果表明，80 ℃微波晶化及

(Mg)/

(Al) = 2时所制催化剂COS水解性能最佳，其在反应气含1.0%（体积分数）O

气氛中，COS转化率及H

S选择性均为100.0%并保持540 min；但O

体积分数增大至1.5%时，COS转化率及H

S选择性明显降低（分别下降63.2%与68.8%），主要归因于高O

体积分数下H

S催化氧化导致催化剂表面硫沉积加剧；无O

环境中H

S在催化过程中导致催化剂中毒，且中毒程度随H

S质量浓度增大而加剧：含198 mg/m

S下COS转化率和H

S选择性在100 min时分别降至37.4%和5.3%；1.0% O

与198 mg/m

S共存进一步加快催化剂失活，加剧了表面硫酸盐化及中弱碱相对含量减小，且H

S对催化剂的不利影响显著大于O

，反应85 min时COS转化率与H

S选择性分别仅为20.2%、1.4%。

Abstract

COS hydrolysis catalysis is important in industrial gas purification and desulfurization. MgAl hydrotalcite-based oxides (MgAl-MMO) can effectively catalyze COS hydrolysis in a simple atmosphere (COS + H

O). However

the catalytic effect of O

S on MgAl-MMO is not clear

and the existing synthesis methods are time-consuming. The feasibility of microwave-assisted synthesis of MgAl-MMO was explored and its catalytic

behavior under reaction gas containing O

S was investigated. The results show that the best performance of the catalyst for COS hydrolysis is achieved by microwave crystallization at 80 ℃ and

(Mg)/

(Al) of 2. The COS conversion rate and H

S selectivity of the catalysts are 100.0% and maintain for 540 min in in the reaction gas (O

volume fraction of 1.0%). However

the COS conversion rate and H

S selectivity decrease significantly (by 63.2% and 68.8%

respectively) when the O

volume fraction increases to 1.5%

which is mainly attributed to the increase of sulfur deposition on the catalyst surface due to the catalytic oxidation of H

S at high O

volume fraction. H

S in the O

-free environment leads to catalyst poisoning during the catalytic process

and the degree of poisoning increases with the increase of H

S mass concentration: COS conversion rate and H

S selectivity with 198 mg/m

S decrease to 37.4% and 5.3% after 100 mintutes

respectively. The coexistence of 1.0% O

and 198 mg/m

S further accelerate the catalyst deactivation

exacerbate the surface sulfation and the relative content of medium bases and weak bases decreased significantly

and the detrimental effect of H

S on the catalyst is significantly greater than that of O

with the COS conversion rate and the H

S selectivity of only 20.2% and 1.4%

respectively

after 85 minutes of reaction.
