为什么说煤层气是一种清洁高效安全的新型能源

Why Coalbed Methane Is a New Clean Efficient and Safe Energy

随着低碳经济时代的到来,煤层气作为一种清洁优质能源逐渐受到世界的重视。通过煤层气与煤炭、石油和常规天然气等常用化石能源的组成对比,建立了煤层气是一种清洁高效安全新型能源的分析基础。从能源开发历史和能源类型角度说明了煤层气是一种新型能源;从能源燃烧产物角度解释了煤层气是一种更加清洁的能源;从能源热值和能源利用率角度证实了煤层气是一种更加高效的能源;从大气环境保护和煤矿环境安全角度阐明了煤层气是一种更加安全的能源。提出了化石能源优劣程度的主要判别标准,即对于元素组成以C和H为主的化石能源,C/H原子比是决定该能源优劣的主要因素,C/H原子比越小,能源的清洁性、高效性和安全性越好。最后通过对煤层气能源清洁、高效和安全性等特点的研究,揭示了煤层气在能源与环境两方面的重要价值,表明了煤层气开发利用的重要意义。

With the advent of low carbon economy time,coalbed methane(CBM),as is a clean,efficient and Safe energy,is paid more and more attention.By comparing the components of energy resources such as coal,oil and conventional natural gas etc,the analysis base is buildup to verify the problem why CBM is cleaner,efficient and safe energy resource.First,CBM is a new energy showed by it's development history and unconventional properties.Second,CBM is cleaner than other energy resources considering it's combustion products.Third,CBM is more efficient due to it's calorific value and utilization ratio.In addition,CBM is safe in atmospheric environment and coal mine environment.In this paper,C/H ratio is considered to be a key factor to energy resources mainly comprised of carbon element and hydrogen element in determining the quality of the energy.That is to say,the smaller the C/H ratio is,the better(cleaner,more efficient and safer) the energy is.Finally,according to the advantages of CBM,it plays an important role in energy supply and environment protection,which shows the importance of development and utilization of CBM.
