Coal contains harmful trace elements. Especially, mercury has high volatility. Mercury of approximately 27% in coals used in coal fired power plants is released as gaseous elemental mercury in a flue gas to the atmosphere. In an ironmaking system, since large amounts of coal are used as a reducing agent and heat source, there is a possibility that the gaseous elemental mercury emits from some processes. Therefore, an objective in this work is to develop adsorbents that are able to capture the gaseous elemental mercury in an air atmosphere and a reducing atmosphere. In this work, carbonized wastes (sewage sludge, paper sludge, woody biomass and municipal solid waste) were used as experimental samples. As a result, the municipal solid waste char has the highest property to capture the elemental mercury in the air atmosphere at 423 K. From results of X-ray Absorption Near Edge Structure (XANES) analyses, the mercury captured in the municipal solid waste char was mainly captured as mercury sulfide (HgS) on the char. On the other hand, a mercury capture ratio of the municipal solid waste char in the reducing atmosphere was lower than that in the air atmosphere.

No.1-1 Oxy-Fuel Coal Combustion Behavior in a Fluidized Bed

ASAI Ryosuke, YOSHIIE Ryo, UEKI Yasuaki, NARUSE Ichiro

Proceedings of Conference on Coal Science Vol. 53 ( 0 ) page： 2 - 3 2016

Publishing type：Research paper (scientific journal) Publisher：The Japan Institute of Energy

Oxy-Fuel coal combustion has drawn attention in the world as useful technique to achieve carbon dioxide capture and storage (CCS). It is a technology to enrich CO2 in exhaust gas by the flue gas recirculation with additional pure O2 to combustion atmosphere, which makes easy to capture CO2. Meanwhile, bubbling fluidized bed coal combustion has advantages of direct sulfur capturing in bed material and decreasing of thermal NOX in low combustion temperature. Objectives of this paper are to understand hazardous emission behaviors during the oxy-coal fluidized bed combustion under the actual flue gas recirculation condition, compared with those under the air and CO2-O2 combustion conditions. A lab-scale fluidized bed reactor was utilized as the experimental equipment. Dusts were separated from flue gas via cyclone downstream, and carbon contents in them were analyzed to estimate carbon balances through the reactor.

No.1-3 Evaluation of coalescence and detachment behaviors of ash particle in pulverized coal combustion

One of the major problems in pulverized coal combustion process is ash deposit phenomena such as slagging and fouling. The behaviors of Included Minerals (IM) and Excluded Minerals (EM) are an important factor to predict and control such ash deposit phenomena. Then, we sampled pulverized coal particles in different carbon conversion and coal types using Drop Tube Furnace (DTF) and analyzed ash particles by Computer Controlled Scanning Electric Microscope (CCSEM) in previous study3). In this study, we made the models of single pulverized coal particle in combustion process using data gotten by CCSEM analysis and evaluated IM/EM particle properties such as particle number, particle diameter and composition in different carbon conversion and coal types through the simulation.

No.1-2 Capture and Oxidation Mechanism of Mercury in Coal Combustion Exhaust Gas

SAKAIDA Masaya, YOSHIIE Ryo, UEKI Yasuaki, NARUSE Ichiro

Publishing type：Research paper (scientific journal) Publisher：The Japan Institute of Energy

Coal combustion is one of the major mercury emission sources. The majority of mercury emissions from coal combustion is an elemental mercury. This is because oxidized mercury is water-soluble and easily captured, but on the other hand elemental mercury is water-insoluble and difficult to capture. In this study, we expected the De-NOx catalyst to have a mercury capture/oxidation performance and performed mercury capture/oxidation experiment using the De-NOx catalyst as a sorbent. In the result, when HCl is present in the atmosphere, the De-NOx catalyst oxidized mercury and when HCl is not present in the atmosphere, the De-NOx catalyst showed high mercury capture performance. Furthermore, De-NOx catalyst maintained high mercury capture performance at a relatively high temperature (673 K).
