Abstract Tar catalytic removal by char is a promising technology for gasification process because of its porous structure, good catalytic activity, low cost, and easy to treatment after deactivation. To provide comprehensive information on the tar catalytic removal by char, this study focuses on the ongoing efforts and advances from fundamental researches to the industrial applications. The tar removal efficiency by char much depends on reaction conditions and char property, such as char origin,...

Gasification is attracting attention as a method of chemically recycling waste plastics. However, gasification generates tar, which consists primarily of polycyclic aromatic hydrocarbons (PAHs), as a byproduct. Our study aims to elucidate the steam gasification behavior of tars from acrylonitrile butadiene styrene (ABS), polycarbonate (PC), and polyethylene (PE) plastics in a batch furnace using mass spectrometry. The tar fraction varies depending on the type of plastic. The plastics tars from A...

Abstract The ionization source based on glow discharge plasma using ambient air is driven by a pulsed direct-current voltage for soft plasma ionization (SPI). The novelty of this work is that molecular ions [ M + 13 ] + related to the analyte species (M), which may be formed by numerous oxidation, can be dominantly detected as a base peak with little or no fragmentation of them in an air plasma at a pressure of several kPa. The unique ion [ M + 13 ] + was assigned to the oxidation product, [ M +...

This work examined the reaction behavior and kinetics of in situ char gasification and the corresponding biomass devolatilization by TGA based on the non-isothermal method. Four kinds of devolatilization atmosphere (N2, N2+CO2 (10%), N2+CO2 (50%), N2+steam (10%)), three kinds of gasification atmosphere (N2+CO2 (10%), N2+CO2 (50%), N2+steam (10%)), and different heating rates (5, 10, 20, 30, 40 K/min) were adopted. With the increase of heating rate in each atmosphere for biomass devolatilization ...

Abstract Hydrogen chloride (HCl) non-thermal plasma was applied to introduce Cl active sites on biochar prepared from sorghum straw in this study. Surface modified biochar was then placed in flue gas with typical components to investigate its elemental mercury (Hg0) capture ability. To elucidate the adsorption mechanism & binding properties, samples were characterized by N2 adsorption, scanning electron microscopy with energy dispersive spectrometer (SEM-EDS) and X-ray absorption near edge struc...

Integrated coal gasification combined cycle systems are expected to raise the power generation efficiency of coal-fired power plants. In Japan, coal gasifiers are required to treat various kinds of coal imported from many countries because almost all of the coal is imported from abroad. In an entrained-bed coal gasifier, the slag-tapping hole must be heated adequately to discharge the molten slag. Thus, a heating technique has been developed to heat the hole from below, without using any auxilia...

Abstract In this study, the effects of mechanical stresses on the shedding of ash deposits in a coal-fired boiler were evaluated. We have confirmed that the shedding occurred because of the fracture within the initial deposit layer, which was formed by powdered ash residues. Therefore, assuming that the mechanical stress acting on the initial layer influenced the shedding, the distribution of the tensile stress and shear stresses acting on the initial deposit was calculated on the basis of elast...

Abstract This study describes an ionization source for mass analysis, consisting of glow discharge plasma driven by a pulsed direct-current voltage for soft plasma ionization, to detect toxic volatile organic compounds (VOCs) rapidly and easily. The novelty of this work is that a molecular adduct ion, in which the parent molecule attaches with an NO + radical, [M + NO] + , can be dominantly detected as a base peak with little or no fragmentation of them in an ambient air plasma at a pressure of ...
