Title

The role of carburization temperature on the molybdenum carbide surface and their catalytic activity

Pages

  91-97

Abstract

 The surfaces of molybdenum carbide were varied by changing the Carburization temperature between 823 and 1123 K. The surfaces of the catalytic material were investigated using in-situ temperature program carburization followed by temperature program Reduction and Oxidation. In-situ temperature program Oxidation (TPO) showed the surfaces of the catalysts contain a similar amount of carbonaceous deposit, while temperature program Reduction (TPR) showed their ability to consume hydrogen in different amounts. The result shows the surface of the carbide at 823 K contained oxygen, while those carburized at higher temperature (≥ 923 K) were pure carbide. The catalysts tested for Hydroisomerization of n-heptane and the catalyst with oxycarbide surface showed higher Activity and iso-heptane selectivity. Hence, Carburization temperature plays a crucial role in the formation of an active catalyst.
