comprehensive utilization technology of by-product C4 from Coal-to-olefin Process

comprehensive utilization technology of by-product C4 from Coal-to-olefin Process

Page view:

The vigorous development of the coal chemical industry in China, enriched the C4 resources. KaiRui has matured technology to utilize the C4 resources from customs to produce value-added chemicals. 

Major processes

1. MTBE is produced by C4 etherification, the isobutylene content in C4 reffinate is lower 0.3%.

2. MTBE is produced by C4 etherification, C4 reffinate to produce 1-butene through selective hydrogenation.

3. To produce TBA from C4 by hydration, C4 raffinate to produce MTBE, then to produce sec-butanol and methyl ethyl ketone by hydration.

4. N-butene isomerization to produce MTBE.

5. Isobutane dehydrogenation to produce MTBE.
