Application of Analytical Pyrolysis in Air Pollution Control for Green Sand Casting Industry
分析裂解技术在砂型铸造空气污染控制中的应用研究

Analytic pyrolysis was conducted to simulate the heating conditions that the raw materials of green sand would experience during metal casting process.The volatile organic compound(VOC) and hazardous air pollutant(HAP) emissions from analytical pyrolysis were analyzed by gas chromatograph-flame ionization detector/mass spectrometry(GC-FID/MS).The emissions from analytical pyrolysis exhibited some similarity in the compositions and distributions with those from actual casting processes.The major compositions...
