splintering

In the course of the expansive transformation of the ethylene plant of Guangzhou General Petrochemical Works,the divisional cracking technology of ethane and naphtha is used to transform the cracking furance,and the transformation rate of ethane has been improved greatly,the circulation of ethane in the system has been reduced effectively.

广石化乙烯装置扩能改造中,采用乙烷、石脑油分区裂解工艺改造乙烯裂解炉,大幅提高了乙烷转化率,有效降低了系统内乙烷循环量,从而提高了乙烯收率,使整个乙烯装置产量达标,取得了良好的经济效益。

The basic principle of analytical pyrolysis was introduced.

介绍了分析裂解技术的基本原理,综述了分析裂解技术在橡胶工程中的应用。

In this work, first a new analytical pyrolysis system was developed by incorpo-rating pyrolysis--gas chromatography/ mass spectrometry with pyolysis--massspectrometry on Hitachi model M--80 doublc-focusing mass spectrometer.

本文报导了在日立 M-80型气相色谱/质谱仪上装上CDS Pyroprobe 100型裂解器,组成既能做裂解色谱/质谱(Py-GC/MS),又能做裂解质谱(Py-MS)的分析裂解系统,通过对一系列的高分子裂解试验,评价了二者的性能。
