TREATMENT OF FEED FOR HIGH SEVERITY VISBREAKING |
| 摘要 |
Prior to upgrading a viscous feed by visbreaking, at least a portion of the feed is treated to remove a heavy phase in specified amounts, whereby the severity of the visbreaking may be increased. The Shell Hot Filtration number of the visbreaking product is reduced by at least 75%, compared to visbreaking of untreated feed at the same severity. |
