Micropore Size Analysis of Activated Carbons Using Nitrogen, Carbon Dioxide and Methane Adsorption Isotherms: Experimental and Theoretical Studies

Three disilanes, (CH3)3SiSi(CH3)3, Cl(CH3)2SiSi(CH3)2Cl, and Cl2(CH3)SiSi(CH3)Cl2, all representing components of the Direct Process residue for the industrial synthesis of chloromethylsilanes, were evaluated for their abilities to reduce carbon dioxide to carbon monoxide upon treatment with fluoride salts. In particular, Cl(CH3)2SiSi(CH3)2Cl proved to be highly efficient upon the use of stoichiometric amounts of potassium bifluoride. DFT calculations performed on the reduction steps with (CH3)3SiSi(CH3)3 and fluorinated analogues of this disilane suggest that the previously proposed pathway involving an intermediate silacarboxylic acid is plausible.

Insight Into

Activated carbon was prepared from nut shells using a conventional two-stage method: carbonization followed by activation. Activation with steam or carbon dioxide as activating agent produced a range of chars of different burn-off. These were characterized for their total and micropore surface areas, and benzene adsorption capacity. Benzene adsorption measurement provided an insight into the effect of porosity development on the adsorptive properties of the adsorbent. It was found that activated carbon products from nut shells were comparable, in terms of adsorption characteristics, with activated carbons from other lignocellulosic precursors. The evolution of porosity of the resulting carbons shows that carbon dioxide is the preferable agent for the production of activated carbon with a narrow micropore size distribution.
