Integrated gasification combined cycle with CO 2 capture and sequestration (IGCC-CCS) emerges as one of the most promising technologies for reducing CO 2 emission from coal power plant without reducing thermal efficiency significantly. However the high capital cost of these plants has limited their deployment. The current solvent-based low-temperature CO 2 capture process (Selexol process) is e...

Ecological disasters resulting from oil spills have created a great need to find more efficient materials for oil spill cleanup. This research highlights the use of a novel macroporous polymeric material based on butyl rubber (BR) as a sorbent in an oil spill cleanup. The sorption capacity of BR for crude oil and petroleum products is 15-23 g g(-1) as compared to the value of 10-16 g g(-1) obta...

Batch sorption experiments using a starch-based sorbent were carried out for the removal of heavy metals present in industrial water discharges. The influence of contact time, mass of sorbent and pollutant load was investigated. Pollutant removal was dependent on the mass of sorbent and contact time, but independent of the contaminant load. The process was uniform, rapid and efficient. Sorption...

Boron compounds are used as wood preservatives as they are both fungicide and insecticide, relatively inexpensive and environmentally acceptable. Nevertheless, in the field of wood protection, borates are only used for indoor non-exposed applications or in association with other biocides, due to their main disadvantage of being readily leachable from treated wood. To overcome this problem, bori...

Sorbent materials based on a hydrazone Schiff base compound, C(14)H(11)BrN(4)O(4), were prepared either by immobilizing the ligand into sol-gel (SG1) or bonding to silica (SG2). The sorbent materials were characterized by FT-IR, EDX, SEM, TEM, and TGA. The sorption characteristics of a matrix of eight transition metal ions (Ag(+), Cu(2+), Co(2+), Ni(2+), Fe(3+), Pb(2+), Zn(2+), and Mn(2+)) usin...

The paper presents our new results about efficiency of wastes based on hydrolyzed polyacrylonitrile textile fibers (HPAN) as sorbents in removal of some dyes from textile effluents. The effect of some experimental variables such as initial dye concentration, sorbent mass, pH, temperature, and contact time were investigated. The sorbent dye sorption systems are described using Freundlich, Langmu...

Sorbent material based on a novel thiosemicarbazone compound, C H N S, was prepared by 12 18 4 immobilizing the ligand into gel matrix (SG). The SG sorbent was characterized by FT-IR, EDX, SEM, TEM and TGA. The competitive sorption characteristics of eight transition metal ions (Ag , Cu , Co , Ni , Fe , Pb , Zn + 2+ 2+ + 3+ 2+ 2+ and Mn ) using batch method was studied using atomic absorption s...

Sorption systems are a prevalent technology in the field of environmental engineering for treating waters contaminated with organic and/or inorganic compounds. Examples of such contaminants include taste and odor, hardness, disinfection byproduct precursors, and arsenic. The primary operating costs for these sorption systems lie in sorbent replacement. Different column arrangements and the use ...
