Title:
PRODUCTION OF MODIFIED GASOLINE REDUCED IN SULFUR, NITROGEN AND OLEFIN CONTENTS
Document Type and Number:
Japanese Patent JP3178515
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a method for modifying a heavy naphtha raw material rich in nitrogen and sulfur contents.
SOLUTION: This method for producing a modified gasoline reduced in sulfur, nitrogen and olefin contents contains a step for feeding a naphtha raw material having an initial nitrogen content, an initial sulfur content and an initial octane value, a step for bringing the led naphtha raw material into contact with an acidic source to produce a nitrogen-reduced raw material having a smaller nitrogen content than the initial nitrogen content, and a step for bringing the nitrogen-reduced raw material into contact with a hydroconversion catalyst system in a hydrogen atmosphere to produce the final product having a larger final octane value than the initial octane value of the raw material. Isomerized components in the final product are increased in comparison with those of the raw material, and the contents of aromatic components are substantially not increased.
