Title:
【発明の名称】オクタン-バレル価を最大にするための低温におけるFCCガソリンの深脱硫
Document Type and Number:
Japanese Patent JP2002530469
Kind Code:
A
Abstract:
Low sulfur gasoline of relatively high octane-barrel value is produced from cracked, sulfur containing olefinic naphthas by hydrodesulfurization at low temperature and low space velocity over either a conventional catalyst, such as CoMo/Al2O3, or a dual functional catalyst, such as CoMo ZSM-5/Al2O3. This approach also minimizes the olefins/hydrogen sulfide re-combination frequently observed at high temperature. The process produces a gasoline having a reduced sulfur content with a less than 5% change in motor octane number and a less than 10% change in research octane number.
