Embodiment 1

[0032] Using organic furfuryl alcohol (FA) as carbon precursor, powdery commercial Y-type zeolite (SiO 2 / Al 2 o 3 =7.4) as a template, and the template carbonization method prepares porous carbon with regular structure and high specific surface area. The specific steps are as follows: 1. Weigh 3 g of powdery Y-type zeolite and dry it under vacuum at 120° C. for 1 hour. 2. Add 10ml of FA to the dry powdered Y-type zeolite under vacuum at room temperature, and start stirring. After 30 minutes, nitrogen gas is introduced to continue stirring for 8 hours, and then impregnated under 1.0MPa nitrogen pressure for 1.2 hours. 3. Filter the FA / Y type zeolite mixture and dry it under air to obtain dry FA / Y type zeolite. 4. The FA / Y-type zeolite obtained in step 3 is washed with o-xylene to remove the FA remaining on the outer surface of the Y-type zeolite (stirring time is 10min), and the FA / zeolite composite is obtained after filtering to remove the detergent and further drying in t...

[0034] Using organic furfuryl alcohol (FA) as carbon precursor, powdery commercial Y-type zeolite (SiO 2 / Al 2 o 3 =7.4) as a template, and the template carbonization method prepares porous carbon with regular structure and high specific surface area. The specific steps are as follows: 1. Weigh 5 g of powdery Y-type zeolite and dry it under vacuum at 120° C. for 1 hour. 2. Add 15mL of FA to the dry powdered Y-type zeolite under vacuum at room temperature, and start stirring. After 30 minutes, nitrogen gas is introduced and stirring is continued for 8 hours, and then impregnated under 1.2MPa nitrogen pressure for 1.5 hours. 3. Filter the FA / Y type zeolite mixture and dry it under air to obtain dry FA / Y type zeolite. 4. Wash the FA / Y-type zeolite obtained in step 3 with o-xylene to remove FA remaining on the outer surface of the Y-type zeolite (stirring time is 10 min), filter to remove the detergent, and dry under air to obtain the FA / zeolite composite. 5. Put the FA / zeolit...

[0036] Using organic furfuryl alcohol (FA) as carbon precursor, powdery commercial Y-type zeolite (SiO 2 / Al 2 o 3 =7.4) as a template, and the template carbonization method prepares porous carbon with regular structure and high specific surface area. The specific steps are as follows: 1. Weigh 10 g of powdery Y-type zeolite and dry it under vacuum at 120° C. for 1 hour. 2. Add 25mL of FA to the dry powdered Y-type zeolite under vacuum at room temperature, and start to stir. After 30min, nitrogen gas is introduced to continue stirring for 8h, and then impregnated under 1.2MPa nitrogen pressure for 1.5h. 3. Filter the FA / Y type zeolite mixture and dry it under air to obtain dry FA / Y type zeolite. 4.

Abstract

A process for preparing porous carbon with regular structure and large specific surface area includes such steps as providing Y zeolite as template, and furfuryl alcohol as carbon precursor, pre-treating the template, preparing organic substance-template compound, preparing carbon-template compound, removing template to fill the organic substance in the nano-arteries of inorganic material, polymerizing, charring and removing template.

Description

technical field [0001] The invention belongs to the field of carbon material science and technology. It relates to a technical method for preparing porous carbon with regular structure and high specific surface area by taking porous inorganic material with regular pore structure as template and organic compound as carbon precursor template method. Background technique [0002] Porous carbon materials (PCM) refer to carbon materials with different pore structures. change over a wide range. Carbon materials with different shapes and properties, such as traditional activated carbon (ordinary activated carbon), super activated carbon (high specific surface area activated carbon), activated carbon microspheres, activated carbon fibers, and carbon molecular sieves, all belong to the category of porous carbon. Since the 1990s, as environmental problems have increasingly become the focus of the world, porous carbon, as an adsorbent material with excellent performance, has made gre...
