Thirty-Fifth Annual INTERNATIONAL PITTSBURGH COAL CONFERENCE University of Pittsburgh · Swanson School of Engineering ABSTRACTS BOOKLET Clean Coal-based Energy/Fuels and the Environment October 15-18, 2018 New Century Grand Hotel Xuzhou Hosted by: The conference acknowledges the support of Co-hosted by: K. C. Wong Education Foundation, Hong Kong A NOTE TO THE READER This Abstracts Booklet is prepared solely as a convenient reference for the Conference participants. Abstracts are arranged in a numerical order of the oral and poster sessions as published in the Final Conference Program. In order to facilitate the task for the reader to locate a specific abstract in a given session, each paper is given two numbers: the first designates the session number and the second represents the paper number in that session. For example, Paper No. 25.1 is the first paper to be presented in the Oral Session #25. Similarly, Paper No. P3.1 is the first paper to appear in the Poster Session #3. It should be cautioned that this Abstracts Booklet is prepared based on the original abstracts that were submitted, unless the author noted an abstract change. The contents of the Booklet do not reflect late changes made by the authors for their presentations at the Conference. The reader should consult the Final Conference Program for any such changes. Furthermore, updated and detailed full manuscripts, published in the Conference Proceedings, will be sent to all registered participants following the Conference. On behalf of the Thirty-Fifth Annual International Pittsburgh Coal Conference, we wish to express our sincere appreciation and gratitude to Ms. Kristen Harper for her meticulous leadership and control of the entire operation of the conference and to Mr. Rui Wang and Mr. Husain Ashkanani for their invaluable assistance in preparing this Abstracts Booklet. Special thanks go to Ms. Xinyuan ZHANG (Summer), CUMT for her great help of this year’s conference. Thank you, Badie I.

A green chemical method has been developed for ash removal from coals. By using the sintering reaction of alkali and minerals in coals, the chemical digestion has been greatly 1.1- Case Studies of Biomass Co-Firing in Full-Scale Pulverized intensified even under mild conditions, by comparison with conventional chemical Coal-Fired Power Plants in China methods. The green chemical method has been applied to a raw coal of 35.55% ash, and achieved a high ash removal rate of >95%, preparing a low ash coal of <2%. By Wang Xuebin, Xi’an Jiaotong University, PR CHINA. comparison with the available results for high ash coals, it has been found that about half the alkali would be spared by the green chemical method with the lower temperatures of Biomass co-firing in pulverized coal-fired (PC) power plants is becoming more and 100-150 °C, and the resulting low ash coal can be used in many advanced fields. more popular in China recently, aiming to reduce CO2 emission, encouraged by the Chinese government. In China, four kinds of biomass co-firing modes have been tested 1.5- Hybrid Eulerian-Lagrangian Simulation of Gas-Solid Fluidized Bed or long-term operated in the full-scale PC power plants in the past 13 years, since the first successful case of Guodian Shiliquan Power Plant in 2005, which case imported the Chen Yang, Haochuang Wu, Chongqing University. technologies and fuel pretreatment equipment from Denmark. The other three typical modes developed in China include (1) molding-biomass co-firing, (2) biomass powde The fluidized reactor is widely used in a number of chemical processes due to its high r direct co-firing, and (3) biogas co-firing, in which, the modes (1) - (2) were designed gas-particle contacting efficiency and excellent performance on solid mixing. and conducted by the authors. In this report, these four kinds of biomass co-firing modes An improved numerical framework based on MP-PIC (multi-phase-particle-in-cell) and the corresponding tested results are introduced, the economic analysis and the method has been developed to simulate the processes of gas-solid flow and chemical existing problems of different modes are compared. reactions in a fluidized bed. In the MP-PIC method, the solid phase is treated as both continuum and discrete phase, the particle stress gradient is calculated on the Eulerian 1.2- Pilot Test of Urea Hydrolysis to Ammonia with Steam Stripping grid and the particle properties are mapped from Eulerian grid to Lagrangian coordinates by the use of interpolation functions and particle size distribution.
