Chemical Reduction of CO_2 to Different Products during Photo Catalytic Reaction on TiO_2 under Diverse Conditions:an Overview

引用

Journal of Natural Gas Chemistry 2007年第3期16卷 217-226页

作者： G.R.dey Radiation and Photochemistry Division Bhabha Atomic Research CentreTrombayMumbai 400085India

The chemical reduction of CO2 remains a challenge with respect to the reversal of the oxidative degradation of any organic materials. The conversion of CO2 into useful substances is essential in developing alternative fuels and various raw materials for different industries. This also aids in preventing the continuous rise in tropospheric temperature due to the green house effect of CO2. In this article an overview of the growth taken place so far in the field of CO2 chemical reduction is pre- sented. The discussion comprises of photochemical methods for the development of different products, viz. CO, CH3OH and CH4, through chemical reduction of CO2. This includes the use of photo catalysts, mainly TiO2, and the role of a hole scavenger （such as 2-propanol） for this purpose.

Performance study and kinetic modeling of hybrid bioreactor for treatment of bi-substrate mixture of phenol-m-cresol in wastewater:Process optimization with response surface methodology

引用

Journal of Environmental Sciences 2013年第4期25卷 698-709页

作者： Sudipta dey Somnath Mukherjee Department of Biotechnology Heritage Institute of TechnologyAnandapurChowbaga RoadKolkata-700107West BengalIndia Environmental Engineering Division Civil Engineering DepartmentJadavpur UniversityRaja S.C.Mallic RoadKolkata-700032West BengalIndia

Performance of a hybrid reactor comprising of trickling filter （TF） and aeration tank （AT） unit was studied for biological treatment of wastewater containing mixture of phenol and m-cresol, using mixed microbial culture. The reactor was operated with hydraulic loading rates （HLR） and phenolics loading rates （PLR） between 0.222-1.078 m3/（m2-day） and 0.900-3.456 kg/（***）, respectively. The efficiency of substrate removal varied between 71%-100% for the range of HLR and PLR studied. The fixed film unit showed better substrate removal efficiency than the aeration tank and was more resistant to substrate inhibition. The kinetic parameters related to both units of the reactor were evaluated and their variation with HLR and PLR were monitored. It revealed the presence of substrate inhibition at high PLR both in TF and AT unit. The biofilm model established the substrate concentration profile within the film by solving differential equation of substrate mass transfer using boundary problem solver tool ＇bvp4c＇ of MATLAB 7. 1 software. Response surface methodology was used to design and optimize the biodegradation process using Design Expert 8 software, where phenol and m-cresol concentrations, residence time were chosen as input variables and percentage of removal was the response. The design of experiment showed that a quadratic model could be fitted best for the present experimental study. Significant interaction of the residence time with the substrate concentrations was observed. The optimized condition for operating the reactor as predicted by the model was 230 mg/L of phenol, 190 mg/L of m-cresol with residence time of 24.82 hr to achieve 99.92% substrate removal.

Present work was undertaken to screen some drought tolerant indigenous aromatic rice cultivars(IARCs),commonly cultivated in West Bengal,India,based on their capacity to produce osmolytes,redox-sensitive phenolic acids and flavonoids,as contrivances for redox-regulation under drought *** glycol induced post imbibitional dehydration stress mediated changes in redox regulatory properties of the germinating seeds of the four IARCs(Jamainadu,Tulaipanji,Sitabhog,Badshabhog),which were assessed in terms of changes in prooxidant accumulation(in-situ localization of reactive oxygen species(ROS)by confocal microscopy,DCFDA(2′,7′-dichlorofluorescin diacetate)oxidation,O2-and H2O2 accumulation),cumulative antioxidative defense(radical scavenging property and total thiol content),ROS scavenging phenolic acids(gallic acid,protocatechuic acid,gentisic acid,para-hydroxy benzoic acid,chlorogenic acid,caffeic acid,syringic acid,salicylic acid,sinapic acid and p-coumaric acid)and flavonoids(catechin,naringin,rutin,quercetin,kaempferol,myricetin and apigenin).The capability of germinating seeds to accumulate osmolytes(like glycinebetaine,proline,soluble carbohydrates and K+ion)and polyphenolic compounds was also correlated with their corresponding redox status and redox biomarkers(conjugated diene,hydroperoxide,thiobarbituric acid reactive substances and free carbonyl content)produced under the same *** results in general showed that accumulation of osmolytes along with the redox-sensitive phenolics and flavonoids conferred the ability to maintain the redox homeostasis under drought stress for the tolerant IARCs(Badshabhog and Tulaipanji).

Based on lower record values,we first derive the exact explicit expressions as well as recurrence relations for the single and product moments of record values and then use these results to compute the means,variances and coefficient of skewness and kurtosis of exponentiated moment exponential distribution(EMED),a new extension of moment exponential distribution,recently introduced by Hasnain(Exponentiated moment exponential ***,2013).Next we obtain the maximum likelihood estimators of the unknown parameters and the approximate confidence intervals of the ***,we consider Bayes estimation under the symmetric and asymmetric loss functions using gamma priors for both shape and scale *** have also derived the Bayes interval of this distribution and discussed both frequentist and the Bayesian prediction intervals of the future record values based on the observed record *** Carlo simulations are performed to compare the performances of the proposed methods,and a data set has been analyzed for illustrative purposes.
