Effects of foam agent on characteristics of thin‐film transistor liquid crystal display waste glass‐metakaolin‐based cellular geopolymer
15-06-2013 | Hau‐Shing Shiu, Kae‐Long Lin, Sao‐Jeng Chao, Chao‐Lung Hwang, Ta‐Wui Cheng, Environmental Progress, 2013
Thin‐film transistor liquid crystal display (TFT–LCD) waste glass comprises mainly SiO2 and Al2O3, which are suitable raw materials for geopolymer. This study investigates the effects of the amount of foam agents on the properties of waste glass‐based cellular geopolymer. In this ...
Inhibition of cellulase, β‐glucosidase, and xylanase activities and enzymatic hydrolysis of dilute acid pretreated wheat straw by acetone‐butanol‐ethanol fermentation products
13-06-2013 | Benkun Qi, Xiangrong Chen, Su Yi, Yinhua Wan, Environmental Progress, 2013
Simultaneous saccharification and fermentation has been regarded as a promising process for bioconversion of lignocellulosic biomass to acetone‐butanol‐ethanol (ABE); however, there exits potential inhibition of cellulase, β‐glucosidase, and xylanase by the fermentation product(s) due to ...
Sorption of phosphamidon onto microwave synthesized zeolitic material
04-06-2013 | Bhavna Shah, Piyush Jadav, Ajay Shah, Environmental Progress, 2013
Bagasse fly ash (BFA) a sugar industry waste had been collected and converted to zeolitic material (MZBFA) by combined conventional and microwave reflux method. The synthesized sorbent has been characterized using various techniques such as FTIR, XRD, and SEM. BFA and MZBFA were used for ...
Preparation and characterization of activated carbon from Kraft lignin via KOH activation
03-06-2013 | Xian‐Fa Li, Qing Xu, Yao Fu, Qing‐Xiang Guo, Environmental Progress, 2013
Kraft lignin (KL), which is largely obtained from Kraft pulping process, is typically utilized to generate steam, electricity, and heat. The huge amount of KL can also be utilized for various purposes such as producing biofuels, chemicals, and materials. In this work, industrial waste KL ...
Photoelectrochemical properties of an active site working on Fe‐SBA‐15 catalyst: Application to the water reduction under visible light irradiation
03-06-2013 | A. Boudjemaa, M. Trari, K. Bachari, Environmental Progress, 2013
Iron‐substituted mesoporous silica, Santa Barbara Amorphous (Fe‐SBA‐15) molecular sieve with Si/Fe ratio of 50 is prepared by microwave‐hydrothermal method. The photoelectrochemistry reveals a metal deficiency and the oxide exhibits P type conductivity with activation energy of 20 meV. The ...
Direct production of gasoline and diesel fuels from biomass via integrated hydropyrolysis and hydroconversion process—A techno‐economic analysis
31-05-2013 | Eric C.D. Tan, Terry L. Marker, Michael J. Roberts, Environmental Progress, 2013
A techno‐economic analysis (TEA) is performed to investigate the production of gasoline and diesel range hydrocarbon fuels by conversion of woody biomass via Gas Technology Institute (GTI)'s integrated hydropyrolysis plus hydroconversion (IH2) process. The processing capacity is 2000 dry ...
Pilot‐scale sequential anaerobic–aerobic biological treatment of waste streams from a paper mill
29-05-2013 | Che‐Jen Lin, Pengchong Zhang, Pruek Pongprueksa, James Liu, Simon A. Evers, Peter Hart, Environmental Progress, 2013
The pulp and paper industry produces a large quantity of wastewater containing recalcitrant organic compounds. In this study, a pilot‐scale anaerobic–aerobic sequential system was employed to treat four different waste streams produced in a kraft pulp and paper mill. The system consisted of ...
Investigation of color removal from methylene blue containing solutions by electrocoagulation/flotation in a batch‐agitated electrochemical reactor
28-05-2013 | Ghadir R. Mohammed, Taghreed M. Zewail, Yahia A. El‐Tawail, Environmental Progress, 2013
The performance of a batch‐agitated cell for the electrocoagulation/flotation (ECF) of methylene blue (MB) has been investigated. The batch‐agitated cell consisted of 45° pitched iron paddle anode and a horizontal iron disc cathode which was fixed at the bottom of the vessel. The ...
Characterization of engineered biochar for soil management
28-05-2013 | Zsuzsa A. Mayer, Yousif Eltom, Dwayne Stennett, Elisabeth Schröder, Andreas Apfelbacher, Andreas Hornung, Environmental Progress, 2013
Pyrolysis is an energy conversion technology which by heating organic materials in the absence of oxygen, produces liquid, gaseous, and solid fuel products. Biochar, the solid product, can also be used as a soil amendment and, simultaneously, enables us to sequester carbon in the ...
Characteristics of NO‐reduction by tar‐included syngas from an updraft gasifier
30-04-2013 | Rui‐zhi Zhang, Ren‐hao Yin, Yong‐hao Luo, Environmental Progress, 2013
Experiments of nitric oxide reduction by the tar‐included syngas from a small biomass updraft gasifier have been carried out on a tubular reactor under a temperature range of 900 to 1200°C. The initial mole fraction of NO was 1000 ppm and that of the oxygen and gasification syngas were ...
