为了寻找一种节约煤炭的替代品，一种微藻。普通小球藻（Chlorella vulgaris，C.将淡水中广泛存在的一种生物活性物质（vulgaris）引入煤的热解过程。本文对C.采用热重分析（TGA）对普通煤和混煤（CCB）进行了热重分析，并对C.并分别以普通煤和煤为对照组。结果表明：CCB的TG和DTG曲线与C.结果表明：CCB的DTG曲线在不同的升温速率下有明显的差异; CCB的固相之间存在相互作用;动力学三重峰分别由Kissinger-Akahira-Sunose（KAS）、Flynn-Wall-Ozawa（FWO）和master-plots法确定。研究结果在一定程度上为微藻与煤共热解的进一步研究提供了参考。皇冠版权所有（C）2012由爱思唯尔有限公司出版。保留所有权利。
To find out an alternative of coal saving, a kind of microalgae. Chlorella vulgaris (C. vulgaris) which is widespread in fresh water was introduced into coal pyrolysis process. In this work, the pyrolysis experiments of C. vulgaris and coal blend (CCB) were carried out by TGA, and those of C. vulgaris and coal were also taken respectively as control groups. It was found that: the TG and DTG profiles of CCB were similar to C. vulgaris, but different from coal under various blending ratios; DTG profiles of CCB were different at several heating rates; interaction was observed between the solid phases of CCB; kinetic triplets were determined by the Kissinger-Akahira-Sunose (KAS), Flynn-Wall-Ozawa (FWO), and master-plots method, respectively. The results provide a reference for further study on co-pyrolysis of microalgae and coal to a certain extent. Crown Copyright (C) 2012 Published by Elsevier Ltd. All rights reserved.
