Abstract

The invention relates to an adsorbent for removing sulfides in MTBE and a preparation method and application method thereof and belongs to the technical field of improvement of adsorbents in a petrochemical industry. The adsorbent for removing sulfides in MTBE comprises an active component and a carrier. The active component is a mixture of AgNO3, Zn(NO3)2, Fe(NO3)3 and La(NO3)3. The carrier is a 13X molecular sieve. The adsorbent for removing sulfides in MTBE has the advantages of simple formula, high specific surface area, high specific pore volume, high activity, high stability and remarkable effects of removing sulfides. The invention provides a simple, safe and environmentally friendly preparation method and use method conducive to industrialization.

Description

technical field [0001] The invention relates to an adsorbent for removing sulfide in MTBE, a preparation method and an application method thereof, and belongs to the technical field of adsorbent improvement in petrochemical industry. Background technique [0002] With the continuous increase in the number of motor vehicles, motor vehicle exhaust emissions have become one of the main sources of urban air pollution. The quality standards of gasoline for vehicles have been continuously upgraded, and the restrictions on the sulfur content of gasoline have become more and more stringent. When producing high-grade gasoline, hydrogenation technology must be used to reduce the sulfur content of catalytic gasoline to a certain value, in order to meet the requirements of reconciling high-grade gasoline, and reducing the sulfur content of catalytic gasoline will inevitably lead to a decrease in octane number, methyl tert-butyl Methyl ether (MTBE) is used as a gasoline additive (general...
