摘要
Abstract
Ethylene technologies including steam pyrolysis,naphtha catalytic cracking,heavy oil catalytic cracking,direct crude-to-ethylene,coal(methanol)to olefin,biomass ethanol dehydration to ethylene,syngas-to-ethylene and methane to ethylene are reviewed. The development status and characteristics of each process are described and the development trend of ethylene industry in China is analyzed in many ways including cost,investment,raw material and product. It is concluded that the naphtha-base ethylene will occupy the dominant position for a long time in China and have greater optimization space in the raw material cost,diversification and integration. With low oil price, CTO/MTO and other non-oil routes will be suppressed,but with CTO/MTO project under construction coming on stream and technological progress,the proportion of CTO/MTO capacity accounting for the total ethylene capacity will increase. MTO is decided by the stable inexpensive methanol source. Ethane-base ethylene is decided by ethane supplies and the price in China. R & D investment of methane to ethylene and syngas to ethylene should be enhanced,striving for breakthroughs in core technologies such as catalysts and for solving engineering problems.关键词
