Adsorption and Aggregation of Asphaltenes in Petroleum Dispersed Systems

Abstract

This paper describes the asphaltene adsorption at the surface of mineral powders which are a framework of oil reservoir by near IR (NIR) spectroscopy. Exptl. procedure of surface asphaltenes concn. measurement is proposed. Adsorption parameters are evaluated in a Langmuir approxn. of monomol. layer occupation. Adsorption characteristics are important for permeability coeff. estn. in Darcy law. [on SciFinder(R)]
