Beschreibung
Zusammenfassung:	The present invention relates to a process of preparing a chloride adsorbent with natural binder wherein the organic binder is used to bind metal oxide powder altogether and polymethyl methacrylate (PMMA) or carbon black is used as porogen. The chloride adsorbent is then extruded, left at room temperature, dried and burned to form pores. The prepared adsorbent can efficiently remove the chloride compounds in both forms of inorganic chloride e.g. hydrogen chloride (HCI), organic chloride e.g. vinyl chloride (VCI) and trichloro ethylene (TCE) from the hydrogen stream generated from the continuous catalytic reforming unit, in the actual operation in the oil refinery and aromatic substance production facilities. The adsorbent prepared according to the present invention contains metal oxide of zinc in an amount of up to 99.5-99:8% by weight.
