Magnetic Activated Carbon

Magnetic coal-based activated carbon was prepared from Taixi anthracitic coal in the presence of magnetite (Fe3O4). The magnetic activated carbon samples were characterized by N2 adsorption, XRD, FTIR and vibrating sample magnetometer (VSM). It was found that the magnetic activated carbon had a high surface area of 993.5 m2/g with 4% Fe3O4 and a saturation magnetization of 2.4158 emu/g for magnetic separability. The results showed that the magnetic properties of MAC are provided by Fe3O4 and Fe. In the presence of Fe3O4, the rate of carbonization and activation increase to form a large surface area and a high pore volume. Moreover, the addition of Fe3O4 can greatly promote the number of both micro-pores and meso-pores in activated carbon.

In the present research, activated carbon-supported sulfonic acid catalysts were synthesized and tested as pretreatment agents for the conversion of switchgrass into glucose. The catalysts were synthesized by reacting sulfuric acid, methanesulfonic acid, and p-toluenesulfonic acid with activated carbon. The characterization of catalysts suggested an increase in surface acidities, while surface area and pore volumes decreased because of sulfonation. Batch experiments were performed in 125 mL serum bottles to investigate the effects of temperature (30, 60, and 90 °C), reaction time (90 and 120 min) on the yields of glucose. Enzymatic hydrolysis of pretreated switchgrass using Ctec2 yielded up to 57.13% glucose. Durability tests indicated that sulfonic solid-impregnated carbon catalysts were able to maintain activity even after three cycles. From the results obtained, the solid acid catalysts appear to serve as effective pretreatment agents and can potentially reduce the use of conventional liquid acids and bases in biomass-into-biofuel production.
