A method for synthesizing petroleum sulfonate in a microreactor

The invention discloses a method for synthesizing petroleum sulfonate in micro reactors. The method is mainly characterized in that: a) wide petroleum fraction serving as a raw material and liquid SO3 serving as a sulfonating agent undergo continuous sulfonation reaction in a first micro reactor in the presence of a solvent to generate petroleum sulfonic acid; b) the petroleum sulfonic acid is directly neutralized by using aqueous ammonia to generate the petroleum sulfonate without an ageing process, wherein the neutralization reaction is performed in a subsequent second micro reactor; and c) a micro mixing channel and a micro heat exchange channel are integrated in each micro reactor, and the temperatures of the sulfonation reaction and the neutralization reaction are adopted by adopting cooling media. By using efficient heat transfer and mass transfer properties of the micro channels, the wide petroleum fraction and the liquid SO3 are synthesized into the petroleum sulfonate by sulfonating; the petroleum sulfonate has high active substance content and low interfacial tension; safe, efficient and clean production equipment and a production process capable of realizing strengthened processes are adopted in the method; and the method is suitable for large-scale continuous industrial production of a petroleum sulfonate surfactant for tertiary oil recovery.
