Abstract:
The objective of this work was to study the removal of nitric oxide by Fe/SUZ-4 zeolite
powder and Fe/SUZ-4 zeolite membrane. There are 2 parts of experiments. In the first part, the
K/SUZ-4 zeolite was synthesized via hydrothermal process. Different amounts of Fe (II) were
loaded in the synthesized K/SUZ-4 with different weight percentages: 1, 3, 5, 8 and 10 by
conventional ion exchange method. The reduction of NO by H2 in excess oxygen was studied
with fixed bed reactor at temperature in the range of 100-400 °C. 5 wt. % Fe/SUZ-4 exhibit high
activity for NO reduction and NO conversion of 59 % can be achieved at 300 °C. The second part
was synthesis of Fe/SUZ-4 zeolite membrane on mullite tube supporter with 5 wt. % Fe/SUZ-4
colloidal solution using spin coating. The reduction of NO was performed in membrane reactor at
300 °C and NO conversion was 18 %. Development of Fe/SUZ-4 zeolite membrane with packing
5 wt. % Fe/SUZ-4 powder has been achieved high activity of NO conversion with 65.5 %
