Ni/ZnO–HZSM-5 adsorbents with diff erent ratios of Ni/ZnO were synthesized by incipient wetness impregnation.HZSM-5 was calcinated at 500°C for 3.0 h before using.A total of 4.95 g of Ni（NO 3）2·6H 2 O was dissolved in 6.0 mL distilled water and followed by the addition of6.1 g of Zn（NO 3）2·6H 2 O under stirring at 90°C in water bath.The mixture solution was dropwise added into 4.0 g HZSM-5 and ultrasound-treated for 15 min，followed by stirring at 90°C in water bath for 4 h，evaporating the redundant water.The mixture was aged at 25°C for 8 h.After aging，the mixture was dried at 120°C overnight and followed by calcination at 550°C in air for 6 h in a muffl e furnace.The temperature of the muffl e furnace was heated up to 550°C with a ramp rate of 4°C per min.Finally，the powder was tableted and ground to 20–40 mesh adsorbents.For comparison purposes，Ni/ZnO–Al 2 O 3 adsorbent was synthesized using the same method，and Ni/ZnO was synthesized by co-precipitation.The adsorbents with diff erent ratios of Ni/ZnO were numbered，as shown in Table 1.
