Isobutylene and dry point
Thread Content
We use a sulfuric acid-based stepped reactor; whenever the isobutylene content in the olefin feed is high, the dry point of isooctane also increases. I don’t know why this happens, and what should be done about it? I would appreciate it if experts could give me some advice
I’m not sure what the isobutylene content is in your area. We usually control the isobutylene level, as it is quite reactive during alkylation reactions; high levels of isobutylene can lead to side reactions. It is recommended to increase the alkene-to-isobutylene ratio appropriately.
