Abstract
A process for hydrotreating acidic compounds of an acidic petroleum oil is disclosed. The process includes contacting the acidic petroleum oil with a hydrogen donor solvent to thereby produce a treated petroleum oil. The process can further include contacting a fraction or a full-boiling range portion of the treated petroleum oil with a hydrogenation catalyst in the presence of hydrogen and under process conditions sufficient to hydrogenate at least a portion of the hydrocarbons of the fraction or full-boiling range portion; and utilizing at least a portion of the hydrogenated fraction or full-boiling range portion as the hydrogen donor solvent.
Claims33
A process for hydrotreating acidic compounds of an acidic petroleum oil which comprises:
- contacting an acidic petroleum oil comprising at least one acidic compound with a hydrogen donor solvent at process conditions sufficient to promote hydrogen transfer from said hydrogen donor solvent to said at least one acidic compound of said acidic petroleum oil, thereby producing a treated petroleum oil.
A process for hydrogenating acidic compounds of an acidic petroleum oil which comprises:
- contacting an acidic petroleum oil comprising at least one acidic compound with a hydrogen donor solvent at process conditions sufficient to promote hydrogen transfer from said hydrogen donor solvent to said at least one acidic compound of said acidic petroleum oil, thereby producing a treated petroleum oil;
- removing a fraction from said treated petroleum oil;
- contacting said fraction with a hydrogenation catalyst in the presence of hydrogen and under process conditions sufficient to hydrogenate at least a portion of the hydrocarbons of said fraction;
- and
- utilizing at least a portion of said fraction as at least a portion of said hydrogen donor solvent.
A process for hydrogenating acidic compounds of an acidic petroleum oil which comprises:
- contacting an acidic petroleum oil comprising at least one acidic compound with a hydrogen donor solvent at process conditions sufficient to promote hydrogen transfer from said hydrogen donor solvent to said at least one acidic compound of said acidic petroleum oil, thereby producing a treated petroleum oil;
- contacting a portion of said treated petroleum oil with a hydrogenation catalyst in the presence of hydrogen and under process conditions sufficient to hydrogenate at least a portion of the hydrocarbons of said portion of said treated petroleum oil, thereby producing a hydrogenated treated petroleum oil;
- and
- utilizing at least a portion of said hydrogenated treated petroleum oil as said hydrogen donor solvent.
