摘要

向使用绿色建筑材料的过渡代表了行业的重大转变,旨在减少对环境的影响并提高可持续性。这方面的一个具体例子是木质素基粘合剂的发展,以生产绝缘材料。了解和分析新型粘合剂的工艺排放对于可持续生产和法律合规至关重要。在本研究中,采用直接热萃取气相色谱-质谱法,开发了一种具有成本效益和时间效率的实验室方法来模拟矿棉固化过程中的排放。研究了影响挥发性有机化合物(VOC)排放的因素,如流量、停留时间和热解吸步骤中的大气(空气或He),以确定影响排放化学成分的主要因素,并更好地复制工业过程。还开发了一种模拟工厂生产材料的粘合剂浸渍的实验室方法。结果表明,只有大气对排放的化学成分有显著影响。排放物中最丰富的化合物是乙二醇,其次是脂肪族酮、醛类(来自矿物油氧化)和酚类(来自木质素降解)。实验室模拟的挥发性有机化合物排放量与工业测试的结果非常吻合,尤其是在大气中。本研究建立了一种评估新型木质素基粘结剂VOC排放化学成分的方法,有助于深入分析其环境影响。

Emission simulation using direct thermal extraction gas chromatography-mass spectrometry: Case study with curing of lignin-based binder

Emission simulation using direct thermal extraction gas chromatography-mass spectrometry: Case study with curing of lignin-based binder
The transition towards using green construction materials represents a significant shift in the industry, aimed at reducing environmental impact and enhancing sustainability. A specific example of this is the development of lignin-based binders to produce insulation materials. Understanding and analyzing the process emission of novel binders can be crucial for sustainable production and legislative compliance. In this study a cost-effective and time-efficient laboratory method was developed to simulate emissions from the mineral wool curing process using direct thermal extraction gas chromatography mass spectrometry. Factors affecting the emissions of volatile organic compounds (VOC), such as flow, residence time, and the atmosphere (air or He) during the thermal desorption step, were investigated to identify the dominant factor influencing the chemical composition of emissions and to better replicate industrial processes. A laboratory method for binder impregnation was also developed to mimic factory-produced materials. Results showed that only the atmosphere significantly affects the chemical composition of emissions. The most abundant compounds in emissions were glycols, followed by aliphatic ketones, aldehydes (from mineral oil oxidation), and phenolic species (from lignin degradation). The VOC emissions from laboratory simulations closely matched those from industrial tests, particularly in an air atmosphere. This study establishes a method to evaluate the chemical composition of VOC emissions of novel lignin-based binders, facilitating a thorough analysis of their environmental effects.

期刊介绍: The Journal of Chromatography A provides a forum for the publication of original research and critical reviews on all aspects of fundamental and applied separation science. The scope of the journal includes chromatography and related techniques, electromigration techniques (e.g. electrophoresis, electrochromatography), hyphenated and other multi-dimensional techniques, sample preparation, and detection methods such as mass spectrometry. Contributions consist mainly of research papers dealing with the theory of separation methods, instrumental developments and analytical and preparative applications of general interest.
