Adsorption Characteristics of Benzene on Biosolid Adsorbent and Commercial Activated Carbons

Abstract

This study selected biosolids from a petrochemical wastewater treatment plant as the raw material. The sludge was immersed in 0.5-5 M of zinc chloride (ZnCl 2 ) solutions and pyrolyzed at different temperatures and times.

Adsorption characteristics of acetone, chloroform and acetonitrile on sludge-derived adsorbent, commercial granular activated carbon and activated carbon fibers

“…Steam activation of select grades of coal was used to produce C1 (Norit GAC 830, Netherlands). S1 was made of biosludge obtained from the wastewater treatment plant of a petrochemical industry in Kaohsiung, Taiwan, activated by 1.0 M ZnCl 2 , and pyrolyzed at 500 • C for 30 min [13]. The particle size of the granular adsorbent ranged from 1.68 to 2.0 mm (mesh 10-12).…”

Pyrolytic product characteristics of biosludge from the wastewater treatment plant of a petrochemical industry

“…To obtain a stabilized pyrolysis residue weight, 30 min was chosen as the optimal pyrolysis time in these experiments based on a previous study [22]. The nitrogen, carbon, hydrogen, and oxygen constituents were analyzed with an element analyzer (Heraeus CHN-O Rapid Element analyzer, USA).…”

Conductive carbon–clay nanocomposites from petroleum oily sludge

“…Several wastes from the petrochemical industry have been tested for this purpose, such as biosolids and biosludges formed in biological wastewater treatment plants used as raw materials for the fabrication of mesoporous activated carbons with ZnCl 2 as activating agent [6]. In a subsequent work the activated carbons obtained were tested for adsorption of benzene, with the possibility of desorption and reuse [7]. The use of petroleum coke produced as waste in a Mexican petroleum refinery as raw material for activated carbon was reported for application in treatment of heavy metal-containing wastewater [8].…”
