It is important for environmental protection to use waste materials effectively. In this work, we conducted fundamental researches on the application of carbonaceous materials from waste as a reductant for iron oxide. Carbonaceous materials from waste (carbonized municipal waste, carbonized biomass, canbonized sewage sludge) were mixtured with hematite reagent The mixtures were heated up at the temperatures of 1000-1200℃ in N_2 gas by using thermo gravimetric analysis (TG) or batch furnace. In the reduction experiments, weight changes and concentrations of generated gases from samples were measured by electric balance and micro gas chromatograph, respectively. Weight changes ratio was calculated to compare reaction rate and reactive character.

Improved steam co-gasification characteristics of coal and cedar (biomass) blend was observed against additive average behavior for separate gasification of coal and biomass. Similar effect was less pronounced during CO_2 co-gasification. Blends gasified to 800℃ reveal hastened pore development and physical cracking on coal particles. Co-pyrolysis char has higher H/C ratio and exhibits higher reactivity than chars mixed after separate pyrolysis of coal and cedar.

A novel low temperature process to recover base oil from waste lubricating oil is proposed in this study, which is based on solvent extraction with membrane. In this process, organic solvent is circulated in a closed loop, representing a resource saving technology. Residue consists of only impurities in waste lubricating oil, such as suspended particles, aqueous droplets, soot and tar, representing a waste reducing technology. This process includes a fractional distillation, too, but it is for separating out organic solvent from oils. Then, temperature for fractional distillation is lower than 100 degC, representing energy saving technology. Rubber film is utilized as membrane in this process. Rubber film has swelling property when it is immersed in organic solvent. Expanded polymer network structure works as filter to separate impurities from oil dissolved in solvent. Objective in this paper is to verify the feasibility of solvent extraction with rubber membrane to recover base oil from waste lubricating oil. Effect of extraction period, solvent volume and extraction temperature on both yield and quality of the extracted oil was experimentally estimated. Quality of extracted oil was evaluated through measurement of sulfur, carbon residue and carbon number distribution in oil molecules.

No.18 Development of combustion technology for low-rank coals in pulverized coal-fired boiler

PAK Haeyang, AKIYAMA Katsuya, TAKUBO Yoji, TADA Toshiya, UEKI Yasuaki, YOSHIIE Ryo, NARUSE Ichiro

The main purpose of this study is to develop the combustion technology for low-rank coals with low melting point of ash. Various kinds of coals with different melting temperatures and ash compositions were used as the samples for the chemical equilibrium calculations and the pilot-scale combustion experiment. It was confirmed that the deposition fraction of ash obtained by the experiment rapidly increased when the molten slag fraction obtained by the calculation became over 60%. Finally, the combustion tests of the blended coal of low rank coal with bituminous coal were conducted using a 145 MW pulverized coal-fired boiler. The blending mass ratio of low rank coal to bituminous coal was decided, using the coal blending method developed. As a result, the mass of the deposited ash for the blended coal did not greatly increase and no slagging problems occurred for 11 days of boiler operation.
