This Paper evaluates the positions of oil, coal and natural gas as the starting raw materials for ethylene production taking into account of the three factors i. e. degree of energy eonservation, hydrogen/carbon ratio and resource sources and from the viewpoints of energetics, chemistry and economics. In view of the two former factors, oil is preferable to coal. Developing ethylene production based on oil is more reasonable so long as the supply of both oil and coal is amply. The comparison of investment and...

This Paper evaluates the positions of oil, coal and natural gas as the starting raw materials for ethylene production taking into account of the three factors i. e. degree of energy eonservation, hydrogen/carbon ratio and resource sources and from the viewpoints of energetics, chemistry and economics. In view of the two former factors, oil is preferable to coal. Developing ethylene production based on oil is more reasonable so long as the supply of both oil and coal is amply. The comparison of investment and production cost between via pyrolysis of petroleum hydrocarbons and from methanol indicates that the price and availability of the row materials have significant impact on the ethylene production cost, Therefore, it is preferable to develop ethylene production technology based on methane, syngas or methanol actively as long as the supply of coal is amply and that of oil is short. In the ethylene production from methanol, both the methanol conversion rate and yields of olefins are higher. There are demonstration units built, so the said process is promising for commercialization. Since China has rich coal resources, developing ethylene production technology based on coal has both practical and strategical importance, which is worth paying great attention to.

从能量学、化学和经济学观点出发,以能量保持率、氢碳比和资源来源三个因素评价了石油和煤作为生产乙烯的起始原料的优劣。从前两因素考虑,石油优于煤。当石油系原料和煤系原料都有充足供应时,以发展由石油系原料制乙烯的生产更为合理。由石油烃裂解乙烯和由甲醇制乙烯的投资和成本的比较可知,乙烯成本受原料价格(来源)的影响极大。所以,在缺乏石油系原料来源而煤系原料供应充裕的情况下,应积极开发由甲烷、合成气或甲醇制乙烯的技术。其中,由甲醇制乙烯,甲醇转化率和烯烃产率较高,已有示范装置,工业化希望很大。我国煤炭资源丰富,研究开发由煤系原料制乙烯的生产有现实意义和战略意义,值得重视。

Studies on the thermal properties of four petroleum pitches for spinning and A240 pitch after concocting Were made by thermal gravimetric analysis (TGA) , thermomechanical analysis (TMA) and differential scanning calorimetry (DSC) . Relative thermal stability, vitrification transformation temperature (Tg) and relationships between specific heat and temperature of the five pitches were investigated.Analysis and comparison were also made between different pitches.
