摘要：

Gallium nitrate-impregnated NaZSM-5 and HZSM-5 light paraffin aromatization catalysts have been reduced via hydrogen in a microbalance, and a disparity in the degree of reduction of gallium was determined. This result suggests that catalytic activity differences in the two materials may be associated with the degree of gallium reduction.
