Preparation and Evaluation of Adsorbents from Coal

Preparation and Evaluation of Adsorbents from Coal

CdII and PbII ions removal using adsorbents prepared from sub-bituminous coal lignite and a blend of coal and Irvingia gabonensis seed shells was investigated. Fourier transform infrared scanning electron microscope and X-ray fluorescence analyses implicated hydroxyl carbonyl Al2O3 and SiO2 as being responsible for attaching the metal ions on the porous adsorbents.

Preparation of Activated Carbons from Mongolian

Preparation of Activated Carbons from Mongolian

Preparation of activated carbons by a physical activation technique is performed using the methods of coal pyrolysis and gasification at different temperatures. As increasing pyrolysis temperature from 520C to 700C the yield of activated carbons from the Khuut KH sub-bituminous coal is lowered and amount of micropores increases gradually however there is no development of mesopores by .

International Journal of Coal Geology Elsevier

2020-7-26The International Journal of Coal Geology deals with fundamental and applied aspects of the geology and petrology of coal oilgas source rocks and shale gas resources. The journal aims to advance the exploration exploitation and utilization of these resources and to stimulate environmental awareness as well as advancement of engineering for effective resource management.

Coal preparation in the world current status and

Coal preparation in the world current status and

The Republic of South Africa exports nearly one third of produced coal. Half of coal left in the country is spent to generate power and round 20 of coal is converted to chemicals and fuel products. The best part of the produced coal needs preparation and coal for export is totally subjected to dressing. Turkey mines mainly lignite 95 .

The preparation of synthetic graphite materials with

Lignite obtained from Inner Mongolia of China was used as the starting precursor for the preparation of synthetic graphite materials. The raw coal was ground to powder and then sieved into a particle size of less than 74 m. Lignite powder LC H 2 SO 4 and H 3 PO 4 were proportionally mixed LC g H 2 SO 4 mL H 3 PO 4 mL 1 0.1 5 .
