  • A combustible producer gas composed of H2, CO and CH4 could be obtained by the thermal-chemical conversion of biomass. However, a large amount of particulate matters including tar generated causes the mal-function of turbines and engines or the fouling of pipelines. In this study, a wet scrubber using the soybean oil and bag filter were installed, and the removal efficiency was investigated. Hydrate limestone and wood char base activated carbon were pre-coated on the filter medium to prevent clogging of open pores. The removal efficiencies by the bag filter were 86 and 80% for the hydrated limestone and activated carbon coating, respectively. Overall, the collection when using a series of oil scrubbers and bag filters were 88%, while 83% for the filter coating material.

  • With the development of industry, fine dust is causing difficulties in various fields such as environment, health, and life, and a large amount of pollutants generated from human social activities are emerging as a serious environmental problem due to air pollution. Therefore, in this study, activated carbon was added to remove fine dust and volatile organic compounds by spinning cellulose acetate polymer fibers on a silicon support using the electrospinning method. By varying the activated carbon ratio and electrospinning time, the fine dust blocking effect and toluene adsorption performance were confirmed according to the activated carbon ratio and filter thickness. As a result, it was shown that the particles were effectively blocked with the increase in the electrospinning time due to the filter thickness increase. Adsorbed amount of toluene was increased with increase in activated carbon amount. Light transmittance was decrease with increase in electrospinning time, showing that there were light transmittance in filters electrospun for 20~30 minutes.
