Preparation and characterization of adsorbents for treatment of water associated with oil production

Overview on the Effect of Particle Size on the Performance of Wood Based Adsorbent

“…Effect of particle size is a complex phenomenon associated with significant change in physical and chemical properties of substance due to direct reduction of the particles (grains, crystallites), the contribution of the interface to system properties and due to particle size being commensurate with the physical parameters of length dimension [2][3][4][5][6]. Size effects are observed with the reduction in size of structural elements, particles, crystallites and grain below a certain threshold.…”

Remoção de querosene na mistura querosene/água, utilizando bagaço de caju quimicamente modificado

“…Algumas pesquisas vêm sendo desenvolvidas com o propósito de aproveitamento de resíduos da agroindústria como adsorventes em processos de separação por adsorção. Sueyoshi et al, (2012) estudaram a ativação física do tronco de palmeira para preparação de carvão ativado. Resultados preliminares mostraram que esse adsorvente tem capacidade de adsorção superior aos adsorventes comerciais assim como alguns resíduos agrícolas.…”

The reduction of oil pollutants of petroleum products storage-tanks sludge using low-cost adsorbents

“…Various methods such as evaporation, dispersion on surface, oxidation, demulsification, adsorption and electrochemical method have been employed to eliminate or separate the oil hydrocarbon from the wastewater and waste oil [3][4][5][6][7][8][9][10]. Nowadays, membrane processes such as microfiltration, ultrafiltration, nanofiltration and reverse osmosis have also been recommended to remove oil hydrocarbon from water [11][12][13][14][15][16][17][18].…”

“…The adsorption of oil pollutants is one of the methods used for the treatment of oil wastewaters. Several investigations have focused on the adsorption of oil pollutants from gaseous, liquid and solid wastes employing natural adsorbents due to the suitable adsorption properties [1,[6][7][8][9][23][24][25][26][27]. Natural adsorbents used are often mineral adsorbents such as zeolite and bentonite, activated carbon, organic materials like chitosan, cotton fiber and agricultural wastes such as rice and wheat wastes, tea, coffee and coconut hysteresis, peanut wastes, shell and stems of various agricultural products, etc.…”

“…Employing natural adsorbents in the removal of oil and organic contaminants from aqueous and gaseous environments has demonstrated remarkable results [1,[6][7][8][9][23][24][25][26][27]. In this study, we examined the adsorption of hydrocarbons from the sludge of petroleum product tanks using natural adsorbents such as wheat straw, pine fruit, walnut shell, almond shell and sawdust.…”
