Quality issues with MTBE as a raw material for isobutylene cracking
Thread Content
In the coming years, driven by the growth of catalytic reforming and isomerization, the issue of improving the octane rating of catalytic gasoline will no longer be addressed by adding MTBE; instead, MTBE’s future lies in its use for producing isobutylene through cracking. When MTBE is used as a raw material for cracking isobutylene, high quality requirements are imposed. The most important things are purity and the content of C4. My question is: are there any requirements regarding sulfur content? After all, low-sulfur TBE is in short supply at present, and its price is 200 yuan per ton higher than that of high-sulfur TBE.

Check on Longzhong Petrochemical Network: the purity of MTBE should be over 98.5%, with a sulfur content of less than 10 ppm.
The MTBE produced in our factory is used in organic plants for the cracking process to produce isobutylene; the required purity level is 98.7% or higher, and the sulfur content, as indicated in the test reports, is 1PPm or less. This is the actual situation here; the sulfur content before the carbon four feed enters the washing unit is around 330 PPm, while the sulfur content after it exits the washing unit is around 300 PPm.
I fully agree; there is no significant shortage of MTBE in the domestic market. Shandong’s local refining capacity is enormous and continues to grow. The production of high-purity isobutylene from MTBE requires strict standards, with the sulfur content having to be below 10 ppm.
There are requirements, especially for use in butyl rubber, where strict limits are imposed on the sulfur content
Hello, we have high-purity MTBE here. Do you need any? ? My QQ is 1527691677; feel free to contact me if you need anything
High-purity isobutylene used to produce butyl rubber requires strict control of its sulfur content; we carry out desulfurization treatment on the raw material before tetrahydrofuran formation. MTBE, which is used as a raw material for etherification, also needs to undergo light and heavy fraction removal processes, so that its sulfur content remains at approximately 1 PPM.
