Abstract:
     The dehydrogenation catalyst for production of olefine aromatics is charaterized by adding several kinds of metal oxides and silicasol or silica gel in tis composition of iron-potassium-cerium-molybdenum catalyst system, in which the addition quantity of silicasol or silica gel is (by SiO2) 0.05-10% (weight), and the element being in added metal oxides can be at least one or several kinds selected from subgroup IB-VIII B and subgroup III A-VA. The catalyst made by using said method not only possesses very high activity and selectivity, but also possesses higher compression strength and longer application period.
