Production of Activated Carbon from HK Bamboo  

Project Title: Production of Activated Carbon from HK Bamboo

Applicant: Hong Kong University of Science and Technology

Total Approved Grant: $119,500

Duration: 01/09/98 to 31/03/99

Project Status/Remarks: Completed

Scope: To assess the possibility of producing activated carbons from bamboo cane to remove pollutants from gas and liquid phase industrial effluents.

Summary of the Findings/Outcomes:

Six carbon chars were produced in a nitrogen atmosphere at temperatures ranging from 600oC to 900oC. The surface areas and pore volumes for most of these chars were more than double those of chars produced from peat, lignite and some coals. Such chars are likely to be very effective materials for filter media. Also the low percentage volatiles and low ash contents would also make these chars very attractive raw materials for the production of BBQ briquettes. Eleven activated carbons have been produced using a range of temperatures, carbonisation times and chemical activating agents. All the carbons tested so far have reasonably high surface areas and adsorption capacities for phenol and methylene blue dye are also high, particularly for phenol adsorption.
