摘要

摘要: 煤层气与煤伴生作为清洁能源，主要用于工业燃料和发电，而对低浓度煤层气，一般做法是排空，因此煤层气应用领域非常有限。本文介绍了煤层气的开采及提纯技术等研究现状，针对煤层气的分子式结构，提出高值利用煤层气路线，即采用化学气相沉积（CVD）方法，以煤层气为原料制备金刚石。介绍了合成原理与工艺过程，提出了不同浓度的煤层气抽采、发电、提纯、金刚石生产及尾气回收于一体的闭环应用系统。总结获得金刚石制品从工具级、热力学级、光学级到电子级的工艺控制规律，比较分析了CVD工艺方法与装备的优势，概述了气相沉积金刚石在相关领域的应用及研究进展，探讨了气相沉积金刚石作为功能材料的应用优势，为煤层气资源高效利用生产炭材料以及金刚石制备技术革新提供参考。

Abstract: The use of coal bed methane (CBM) to fabricate diamonds by chemical vapor deposition (CVD) is proposed. The method uses a closed-loop system composed of CBM mining, CBM purification, the production of hydrogen from CBM for use in diamond growth, diamond fabrication and waste gas recovery. The requirements for the fabrication of diamonds of different grades for use in cutting tools, thermal management, and optical lens and field emission transistors are introduced as examples of the efficient utilization of CBM to produce different quality diamonds.
