ASPHALTENE STABILISATION AND ANTI-COKING ADDITIVE AND METHOD FOR OBTAINING SAME

摘要

The invention relates to an asphaltene stabilisation and anti-coking additive containing condensed cresol alkyl amine, a surfactant and a hydrogen donor compound. Optionally, the additive contains condensed sulphonic alkylphenyl acids. Preferably, said additives are synthesised from refinery streams without any pre-treatment and they do not require separation and concentration steps after each reaction. The invention also relates to the process used to produce the condensed cresol alkyl amine.
