“…This dependence is clearly traced between the samples of initial asphaltenes (SA-0) and samples SA-5, SA-10, SA-30 and SA-60. For the SA-30 sample, the mass fraction of sulfur was higher than for the other samples; an analogous pattern of the non-linear dependence between the sulfur content and the sulfonation severity has been observed in our previous studies on asphaltenes sulfonation [24,26]. Further sulfonation (with a contact time of more than 60 min) does not lead to a noticeable increase in either the sulfur content or the total acid value of the material.…”

“…Such polyaromatic hydrocarbons are formed in the oil industry as by-products, mainly in tar deasphalting plants; their further disposal is part of the more general problem of heavy oil residues disposal. It was shown earlier that by sulfonating asphaltenes, ion-exchange materials can be obtained that are applicable for water treatment [24][25][26]; some preliminary data on the catalytic properties of these materials were also reported [27]. In this work, the sulfonation of asphaltenes is used as an approach for the preparation of non-porous acid catalysts, as a result of which a set of samples with different sulfonation degrees was obtained.…”

In this study, an approach for the preparation of heterogeneous acid catalysts based on asphaltenes isolated from vacuum residue is proposed. Varying the conditions for the sulfonation of asphaltenes made it possible to obtain materials with an acid value of 1.16 to 2.76 meq g–1 and a total sulfur content of 6.4 to 12.3 wt%. The samples obtained were characterized by acid-base titration, nitrogen adsorption, sulfur elemental analysis and transmission electron microscopy techniques, and were studied as potential acid catalysts in the ketalization reaction between glycerol and acetone. Sulfonated asphaltenes (SA) were characterized by a homogeneous distribution of sulfonic groups over the granule surface and an almost complete absence of a porous structure. The ketalization reaction in the presence of SA proceeded without intradiffusion restrictions; as a result of which, their activity was higher than for known heterogeneous catalysts. The most active SA sample (total acid value, 1.16 meq g–1) had an apparent activation energy of 18.0 kJ mol–1, which was lower than the value obtained for the zeolite BEA-40 (29–53 kJ mol–1) and the Amberlyst 36 resin (27 kJ mol–1), and was close to the value for the homogeneous p-TSA catalyst (14.5 kJ mol–1). The SA heterogeneous catalysts did not show any acid leaching and had no loss of activity after five catalytic cycles, with the total turnover number TON = 7247.

“…Ион алмасу сипаттамаларын салыстырмалы талдау нәтижесінде асфальттардың концентрацияланған күкірт қышқылымен және олеуммен өзара әрекеттесу өнімдері белгілі бір жағдайларда синтетикалық күшті қышқыл сульфокатиониттерден кем түспейтіні және әртүрлі өндірістік су тазарту процестерінде жаңа асфальтен сульфокатиониттері ретінде қарастырылуы мүмкін екендігі көрсетілген. Термиялық талдау нәтижелері асфальтенді сульфокатиониттердің дәстүрлі полимерлі сульфокатиониттермен салыстырғанда термодеструкцияның басталу температурасы жоғары екенін көрсетеді (Yakubov, 2015;Yakubov, 2016;Yakubov, 2017).…”
