中文摘要：

综述了15年来HC-trap技术的研究进展，重点概述了汽车冷启动尾气的组成、分子筛吸附剂的选择及其对芳香烃分子的吸附脱附性能、分子筛的孔道及表面结构对芳香烃分子吸附性能的影响，最后展望了该技术在我国的发展意义及趋势。

英文摘要：

The main advances in HC-trap technology till now are reviewed. The emphases are put on the hydro- carbon constitute in the cold start exhaust, the choice of zeolite adsorbents for dutrex such as toluene, the influence of pore and surface structure on toluene adsorption performance. Finally, the developing tendency for HC-trap technolo- gy in our country is proposed.
