Abstract
Disclosed are embodiments relating to a process for reducing the total acid number of a hydrocarbon feed by contacting the feed with a metal titanate catalyst having an MTiOstructure wherein M is a metal having a valence of 2+, resulting in a hydrocarbon product having a final total acid number lower than the initial total acid number of the feed. The process is useful for pretreating high acid crudes prior to further processing thus avoiding corrosion of equipment used in refining operations. The process can be integrated into conventional refining operations in order to treat various refinery streams. In one embodiment, a process is provided for refining a low acid crude oil and a high acid crude oil by separately introducing a relatively low acid crude oil feed and a relatively high acid crude oil feed to an atmospheric distillation column, wherein the relatively high acid crude oil feed is contacted with a metal titanate catalyst prior to introduction to the atmospheric distillation column.
