The effect of the nature of a modifying additive (Pt, Zn, Ga) on the activity of oxide and zeolite catalysts in ethane dehydrogenation and aromatization
- N.D. Institute of Organic Chemistry, Moscow (Russian Federation); and others
The catalytic properties of Pt, Zn, and Ga deposited on supports of various natures (Al{sub 2}O{sub 3}, SiO{sub 2}, NaZSM, and HZSM) in the dehydrogenation and aromatization of ethane were investigated. Pt-containing catalysts are the most active in the conversion of ethane: the selectivity with respect to ethylene is 25-87% depending on the nature of the support. In the presence of Zn- and Ga-containing catalysts the yield of ethylene is 2-3 times lower than with Pt-catalysts. With HZSM modified by Pt, Zn, or Ga aromatic hydrocarbons (ArH) and methane are the main products of ethane transformation. Ga/HZSM is the most efficient catalyst of the aromatization of ethane under the conditions studied (550 {degrees}C, 120 h{sup -1}).
