摘要

针对我国现有煤热解工艺存在原料利用率低、煤气品质不佳等问题，本文聚焦提出的兰炭制备新工艺中活性组分与兰炭相互作用这一核心科学问题，以神木低阶煤为原料，通过固定床反应器和滴管炉耦合固定床反应器分别探究CO

、H

O单一活性组分及煤热解挥发分在不同温度下与兰炭的相互作用规律，分析其对产物分布及兰炭性能的影响。结果表明，550~700 ℃为神木煤制备兰炭的适宜温度范围。随热解温度升高，兰炭产率降低，灰分与固定碳升高，挥发分与比电阻呈降低的趋势。受限于较大的粒径尺寸，H

O和CO

在650~750 ℃ 可与兰炭发生微弱的气化反应，对灰分和固定碳的影响较小，但显著影响比电阻。此外，煤热解挥发分可抑制兰炭的进一步热解，造成兰炭产率的上升，相较于550 ℃，650 ℃时兰炭产率增加较少，且由于活性组分与兰炭表面的反应导致比电阻下降。本研究明确了活性组分对中低温煤热解兰炭性能的影响规律，为提高原煤利用率、改善煤气品质、煤热解制备兰炭工艺的优化设计及反应器开发提供了理论支撑。

Abstract

In response to issues such as low feedstock utilization and poor gas quality in existing coal pyrolysis processes in China

this study focuses on the core scientific problem of the interaction between active components and blue-coke in the proposed new process for blue-coke preparation. Using low-rank Shenmu coal as the raw material

the interaction laws of single active species (CO

and H

O) and coal pyrolysis volatile with blue coke at different temperature were systematically investigated using a fixed-bed reactor and a drop-tube coupled fixed-bed reactor

respectively. The effects on product distribution and blue coke properties were analyzed. The results show that 550~750 °C is the optimum temperature range for Shenmu coal pyrolysis

to prepare blue coke. As the pyrolysis temperature rises

the blue coke yield decreases

ash and fixed-carbon contents increase

whereas volatiles and specific electrical resistance decrease. Slight gasification reaction occurred between CO

and H

O and blue coke at 650~750 °C

which had little effect on ash content and fixed carbon

but significantly affected the specific resistance. Furthermore

coal pyrolysis volatiles inhibited further pyrolysis of blue coke

leading to an increase in blue coke yield; however

the increase in yield at 650 °C is smaller than that at 550 °C

and the specific resistance decreases due to reactions between the active components and the blue coke surface. This study elucidates the influence of active components on the properties of blue coke at the medium-low temperature range for coal pyrolysis

which provides theoretical support for the utilization of raw coal

the improvement of coal gas quality and the optimization of coal pyrolysis processes and reactor development.
