Abstract: In this study, the asphaltene deposition was modeled during natural depletion process. The Langmuir and Toth adsorption models were used to investigate the monolayer and multilayer asphaltene adsorption phenomena onto core surfaces, respectively. A computer program was written to solve the equations with numerical method and the genetic algorithm […]

Abstract: In this study, bentonite was modified with acidic ionic liquid and ionic liquid-bentonite hybrid characterized with XRD, BET and TGA analyses. The esterification of acetic acid with ethanol was studied over this hybrid and the effect of reaction temperature, type and amount of catalyst, molar ratio and reaction time […]

Abstract: Plastics have become a vital ingredient in the world. Due to their non-biodegradability and low life time, their huge wastes made environmental problems in the world. Chemical recycling of them plastics could be a promising method to overcome this problem. Waste plastics can be converted to feed-stocks or valuable […]
