초록

무촉매 공기 브로잉 공정에서 석유계 감압 잔사유로부터 세미-부로운 아스팔트를 제조하는 경우, 시간에 따른 아스팔트의 조성, 구조, 물리적 성질의 변화를 조사하였다. 공기 브로잉에 의해 지방족 탄화수소 성분이 방향족 탄화수소 성분으로 전이되고, 고분자화 되어 아스팔텐 성분이 증가함을 박막크로마토그래피를 이용한 조성 분석에서 관찰하였다. 처리시간에 따른 방향족화와 고분자화 정도의 증가는 1 H-NMR, 열시차분석, 그리고 열중량분석에서도 확인할 수 있었다. 이러한 아스팔트의 조성과 구조의 변화는 침입도의 감소, 연화점과 인화점의 증가를 초래하였다.

The vacuum residue of petroleum refinery, i.e. asphalt, was modified through a non-catalytic air blowing process to prepare the semi-blown asphalt. Changes in composition, chemical structure, and physical properties of asphalt were examined. The result from the thin layer chromatography showed that the asphaltene content in asphalt was increased by the air blowing on account of the aromatization of aliphatic hydrocarbon and condensation. These changes in molecular structure were also confirmed by 1H-NMR, differential scanning calorimetry, and thermogravimetry. Because of the molecular structure changes, the penetration of asphalt was decreased and the softening point and the flash point of asphalt were increased.

Keywords:semi-blown asphalt;air blowing process;asphaltene;molecular structure;thermal properties;physical properties
