Abstract
소형 반응기를 이용하여 α-Al2O3를 담체로 한 Ru 촉매상에서의 기상의 톨루엔에 대한 수소화반응을 연구하였다. 반응온도 범위는 40 - 140 ℃ 이었고 톨루엔의 분압 범위는 49 - 82 mmHg이었다. 또한 반응의 주생성물은 메틸시클로헥산（methyl-cyclohexane）이었으며 다른 부산물은 무시할 수 있을 정도로 미량이었다.
톨루엔의 전화율은 80 - 100 ℃에서 최대이었다. 그리고 반응속도식은 분압의 항으로 다음과 같이 표현할 수 있었으며,
-（dpTo1/dt） = kpH2pTo1-0.5
50-65 ℃에서 구한 활성화에너지는 15.4 kcal/mol이었다.

The vapor phase hydrogenation of toluene was studied over the ruthenium catalyst supported on alumina in a small-scale reactor. The reaction temperature was in the range of 40-140 ℃, and the partial pressure of toleune from 49 mmHg to 82 mmHg. The main product of reaction was found to be methylcyclohexane, and the other products were in negligible amounts.
The maximum conversion of toluene was obtained between 80 ℃ and 100 ℃. The rate equation in terms of partial pressure could be expressed as
-（dpTo1/dt） = kpH2pTo1-0.5
The activation energy at 50-65 ℃ was found to be 15.4 kcal/mol.
