Figure 5. (A) Effect of Si/Al ratio of PLS-3 on the catalytic performance of Zn2Al3O4/PLS-3-x for syngas conversion; (B) Dependence of E/P and O/P ratios on the Si/Al ratio of PLS-3. Reaction conditions: catalyst, 0.25 g; metal oxide/zeolite mass ratio, 3:2; temperature, 623 K; pressure, 1 MPa; the WHSV of syngas (H2/CO volume ratio = 1:1), 6,000 mL·g-1·h-1; TOS, 10 h. E/P: Ethylene to propylene; O/P: olefin to paraffin; WHSV: weight hourly space velocity; TOS: time on stream.
