coal uses ethylene

What Is The Competitiveness Of Coal-to-ethylene

2020-8-28  One is the ethylene route, which uses crude oil, ethane or methanol as raw materials; it is the most mature process route with absolute market advantage among the existing processes. The second is the synthesis gas route, which uses coal, natural gas, and coke oven gas as raw materials, which is suitable for the relatively abundant coal resources in my country.

Development of a Coke Oven Gas Assisted Coal to

2021-3-12  Developing a coal to ethylene glycol (CtEG) process is of great interest to many countries, especially China. However, because the hydrogen to carbon ratio of the coal-gasified gas is far less than the desired value, the CtEG process suffers from high CO 2 emission and wastes precious carbon resources. At the same, most coke oven gas (COG) is discharged directly or used as fuel, resulting in

A comparison between coal-to-olefins and oil-based ...

2017-11-1  Even if half of the domestic ethylene is produced from coal, there are only 3.8% of the domestic coal production consumed. Because of the increasing coal supply and rising crude oil prices from 2004 to 2014, enterprises in China are trying to replace oil with coal to produce petrochemical products. The CTO project is one of the typical projects.

Coal to Olefins - IHS Markit

COAL TO OLEFINS (October 2011) As demand for oil and natural gas outpaces discoveries of new reserves, coal will regain its importance as a source of energy and as a chemical feedstock. At current production levels, proven coal reserves are estimated to last over a century, with recoverable reserves in around 70 countries.
