Abstract

This paper reports on the preparation of hydrocarbon (HC) trap, which can exhibit the capability to effectively reduce evaporative emission from automotive vehicles. The preparation of HC-trap was accomplished by a dipping method which involved the immersion of a nonwoven material in an aqueous solution containing powdered activated carbon. Four kinds of activated carbon are used for HC-trap preparation. HC-traps were then characterized by scanning electron microscopy (SEM), porosimeter (measurement of pore size ) and tensometer (mechanical properties). We conducted butane working capacity (BWC) and vehicle evaporative emission test to check adsorption performance of evaporative emission. Given the high mesopore volume, the HC-traps exhibited high BWC and low vehicle evaporative emissions. It was also revealed that relatively smaller pore size (5~11 nm) of mesopore could be easily saturated by evaporative emissions with HEEL stabilization. Finally, prepared HC-trap showed excellent performance of vehicle evaporative emission test and high reduction of evaporative emissions which showed 18.4 mg of reduction of total vehicle emissions.


본 논문에서는 자동차의 증발 가스를 효과적으로 감소시킬 수 있는 탄화수소(HC)-트랩을 제조하였다. HC-트랩은 분말화된 네 종류의 활성탄을 함유하는 각각의 수용액에 부직포를 침지시키는 방법으로 제조하였다. 제조된 HC-트랩은 주사 전자 현미경(SEM), porosimeter(기공크기 측정) 및 tensometor(기계적 특성)로 특성을 조사하였다. 또한 증발가스의 흡착성능을 측정하기 위하여 butane working capacity(BWC) 및 차량 증발 배출 시험을 실시하였다. 중간 공극이 높은 경우의 HC-트랩은 높은 BWC 및 낮은 차량 증발 배출량을 보여주었다. 또한 HEEL 안정화 실험에서 상대적으로 크기(5~11 nm)가 작은 중간공극들은 증발가스에 의해 쉽게 포화될 수 있음을 알 수 있었다. 결론적으로 제조된 HC-트랩은 차량 증발가스의 우수한 배출성능과 증발 배출량의 높은 감소를 보여 주었으며, 차량 전체 배출가스 중 18.4 mg의 감소를 나타냈다.
