The ramie mainly use China-specific textile crop production in the world. Accounted for the plants most of the hemp stalk has not been fully utilized. The ramie Stick with a low ash, high carbon content, which is ideal for the preparation of high specific surface area activated carbon raw materials. In this study, ramie, hemp stalk as raw material has developed pore structure of activated carbon were prepared and used in the treatment of oily wastewater using chemical methods to achieve to waste pollution control purposes. In this study, using a two-step chemical Preparation of Activated Carbon, ramie Stick carbonation and chemical activation of the carbonized particles. Ramie, hemp stalk as raw material by 350. C-600. C pyrolysis treatment, prepared as a Ramie Stalk carbide particles. According to the the carbonized particles rate measurement, extracts and FTIR analysis to determine the optimal carbonization conditions, as the first step in a chemical method for the preparation of activated carbon carbonized conditions. The analysis results show that, at 600. C pyrolytic treatment the ramie Stick carbide hot water extract, 1% NaOH extract and alcohol benzene the extractives minimum-OH of the infrared absorption significantly reduced, and a significant increase of the infrared absorption of an aromatic ring structure. This shows that when the pyrolysis temperature reaches 600. Ramie the straw C, most of the tissue is removed, thereby forming a large amount of the pore structure. According to the experimental results, it is determined to ramie Stick as the raw material preparation process of activated carbon, i.e. at 600. C high temperature carbonization treatment of raw materials, then through a different activator (H 3 PO 4 , KOH or of ZnCl 2 ) In a different activation temperature (700 C, 750. C, 800 ° C) Preparation of ramie Shank activated carbon. Experimental study different activator (H 3 the PO 4 KOH or ZnCl 2 ) and activation temperature (700 C, 750 C , 800. C) of the activated carbon yield, the pore structure and specific surface area. Using nitrogen adsorption value measured BET specific surface area of ??activated carbon, through the microscopic structure of the scanning electron microscope observation of activated carbon, after the iodine adsorption value of activated carbon, and methylene blue adsorption value analysis of its adsorption capacity. The experimental results show that the carbonization temperature of 600. C activator is KOH and the impregnation ratio is 1:1, and the activation temperature of 800. C, the preparation of activated carbon pore structure is the most developed, the BET value of 1038m2 g -1 , pore volume of 0.668 cm 3 g -1 iodine adsorption value of 899 mg g -1 , methylene blue adsorption value of 89.25 mg g -1 . SEM picture also shows the pore structure having a honeycomb-like surface of the activated carbon was prepared using KOH, and with elevated activation temperature, the volume and number of the mesoporous activated carbon is also rising. Furthermore ramie Shank activated carbon absorption capacity, oil absorption rate, oil absorption selectivity and oil retention rate, tests the effect of the activated carbon samples prepared in this experiment in the practical application. The results show that the ramie Shank activated carbon has a good oil-absorbing properties, wherein with KOH at 800. C was prepared under the activated carbon oil absorption amount is largest, fastest oil absorption rate, and has a good range selectivity The results are consistent with the structural characteristics of the activated carbon. Based on the above conclusions, ramie, hemp stalk as a raw material can be prepared has developed pore structure of activated carbon and the practical application of good results.
