Excess properties have been worked out taking account for non-ideality of both liquid and vapor phases and compared to the prediction of the average potential theory developed by Prigogine and coworkers (see The Molecular Theory of Solutions , (Amsterdam 1957)) Table I gives the main results. ...
As shown in Table 5, the increase of Co loading amount leads to the improvement of the stability of H2 yield. In addition, it is found that 15% Mo2C/γ-Al2O3 shows higher initial catalytic activity than 15% Mo2C/α-Al2O3. This might be due to the higher surface area of γ-Al2...
