Preparation of anisole in phenol by Zn/HZSM-5 catalyst from walnut shell catalyzed liquefaction

The promotional effect of Zn was investigated relative to the calcining activation HZSM-5. It found that lignin separated from walnut shell could be liquefied into small molecular ethers such as anisole by modified catalyst. Experimental results showed that, after loading Zn, HZSM-5 catalyst retained its original crystal structure, which exhibited good metal dispersion. Besides, due existence two interactions respectively with Al and a Brønsted-Lowry acid on Zn/HZSM-5 surface, remaining intergranular distance increased, particularly for 2% inside in state spherical particle aggregation narrow pore size distribution uniform size. peak intensity Si-O stretching vibration affected content least signal this molecule ether not absence ions, catalytic more distinct. Calculated mass difference method, yield liquid via 59.8%, including phenol represented anisole.
