Adsorbent body including activated carbon and inorganic binder for bonding together activated carbon grains, and method of producing the adsorbent body

A method of producing an adsorbent body having a porous structure for purifying a fluid, said method comprising the steps of:

• preparing a raw material composition including a source material which gives activated carbon, aluminum hydroxide which gives activated alumina, and an inorganic binder for bonding together grains of said activated carbon and said alumina, said raw material composition including 15-70 wt % of said aluminum hydroxide, said inorganic binder including phosphorous pentoxide;
• forming an unfired shaped body of said raw material composition;
• and
• firing said unfired shaped body at a predetermined sintering temperature to produce said adsorbent body having a porous structure comprising said activated carbon, said activated alumina, and said inorganic binder.

A method of producing an adsorbent body having a porous structure for purifying a fluid, said method comprising the steps of:

• preparing a raw material composition including a source material which gives activated carbon, aluminum hydroxide which gives activated alumina, and an inorganic binder for bonding together grains of said activated carbon and said activated alumina, said source material comprising an ash of plant and/or wood, wherein said ash of plant and/or wood comprises 10-30 wt. % of carbon and 10-40 wt. % of phosphorous pentoxide;
• forming an unfired shaped body of said raw material composition;
• and
• firing said unfired shaped body at a predetermined sintering temperature to produce said adsorbent body having a porous structure comprising said activated carbon, said activated alumina, and said inorganic binder.
