They ad&b all organic tid other non-polar compounds from iaseous or liquid phase. Due to the increasing applications of activated carbon, a lot of research has been carried out on the preparation of cost-effective adsorbents as a substitute for activated carbon. Few studies have been devoted to the use of coal waste, cl&lithe, as a starting material to produce an adsorbent. In this paper, the following topics were studied: (1) the preparation of new carbon-aluminosilicate composite adsorbent, elutrilithe activated with potassium hydroxide; (2) the examination of the influence of synthesis parameters on the properties of adsorbents; (3) the comparison of their adsorption behaviour towards benzene, toluenc and xylene.

Using a concurrent downflow circulating fhudized bed not only alleviates the conflict between high conversion and high selectivity, but also can sustain the reaction temperature by easily dispersing the reaction heat, making the operation of reaction regeneration system stable and smooth. Experiments were carried out to test the operating feasibility of the unit, and evaluate the tiuencc of operating an apparatus parameters on the process and the flow characteristics of the reaction regeneration system. fy~~ 459

The excellent work of Bui, Perron, and Read studied several process parameters pertinent to the Cal&nation of green petroleum coke tid the subsequent effect on calcined coke properties. One parameter studied was a calcination rate that was comparatively fast. Other work has shown that the calcination rate may be more important in its effect on anisotropic, or premium, coke properties that on more isotropic coke properties than was suspected by Bui, Perron, and Read.

Effect of coal fly ash on the phyalcal propertlea of %I01464 mortar Urn, M. H. et al., Kongop Hwahuk, 1995, 6, (3), 435-445. (In Korean) For the utilization of fly ash produced in domestic power plants, the properties of mortar using fly ash was studied.
Inter- article variations in particle diameter and chemical composition in coal Ry ashes are significant and can be quantitatively studied using currently available microanalysis techniques. One such technique, computer controlled SEM, is now routinely used to determine chemical compositions and diameters of individual fly ash particles, using statistically significant sample sizes. The paper proposes simple mathematical formulae for expressing the inter-particle variations.
