| titleOfInvention | The preparation method of coffee grounds activated carbon |
| abstract | The invention discloses a kind of preparation method of coffee grounds activated carbon, including pre-treatment, de-oiling, dipping, the step such as activation and cleaning, first pass through and carry out that vacuum pyrolysis de-oiling removes grease in coffee grounds and charing obtains coffee grounds carbon precursor to coffee grounds, then with phosphoric acid as activator in different impregnating ratios（The mass ratio of phosphoric acid and coffee grounds carbon precursor）Lower immersion ultrasound, dry after activation under different vacuum conditions, the influences of the activation condition to coffee grounds Properties of Activated Carbon such as activation final temperature, vacuum, heating rate, soak time, impregnating ratio are considered, prepared coffee grounds activated carbon yield is high, and iodine sorption value and methylene blue adsorption value have exceeded national activated carbon primary standard（Iodine sorption value 1000mg/g, methylene blue adsorption value 135mg/g）, it is the extraordinary material for air purification of absorption property available for the absorption after finishing to toxic and harmful gas such as the formaldehyde in room, whole carbon technique processed avoids blocking of the coffee grounds grease to coffee grounds activated carbon hole, simple possible, duty parameter is stable, green pollution-free. |
