A large amount of them were used for energy conservation of buildings, and recently disposed at landfill sites to be pressured because of large volume to mass. In this study, we attempted to convert resin and glass fiber in the waste glass wool into gas and water glass using sodium hydroxide reaction, respectively. Waste glass wool was cut, sample peace (1 g) and sodium hydroxide (1 – 3 g) put into the reactor, and the reactor was heated with an electric furnace while flowing nitrogen (50 mL/min). After heating to setting temperature (400 550 oC) for 1 – 30 h, the reactor was naturally cooled to room temperature. The generated gas during the reaction was collected by gas pack. After cooling, the residue inside the reactor was washed with nitric acid, filtrates to obtain the residual substance, and silica concentration in the filtrate was measured to calculate the silica extracted content from waste glass wool. By using pyrolysis with sodium hydroxide, waste glass wool can be decomposed by converting the resin into the gases, such as hydrogen and methane, and glass fiber into soluble salt to be extracted into the solution. Waste glass wool can be decomposed by pyrolysis with 3 times weight of NaOH to the sample above 400 o C for 1 6 h.","PeriodicalId":13949,"journal":{"name":"International Journal of Chemical Engineering and Applications","volume":"58 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84167331","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The successful synthesis of the MIP was confirmed by elemental analysis (CHN), Fourier-transform infrared (FT-IR) spectroscopy and scanning electron microscopy (SEM). Then, the effects of various parameters such as pH, temperature, MIP capacity, selectivity, adsorption kinetics and adsorption isotherms were investigated by UV-Vis spectroscopy. The calibration curve was plotted for Prasugrel in these conditions and linear range, limit of detection (LOD) and limit of quantification (LOQ) were reported.

The form of the alpha function was derived by keeping in mind the thermodynamic consistency rules as provided by the limiting conditions in the determination of the generalized parameters in a generic cubic equation of state. Using MATLAB, codes executing a nonlinear program that would minimize errors between DIPPR-estimated vapor pressures between the triple point until the critical point from the alpha function’s vapor pressure prediction has been developed. Thermodynamically consistent parameters were calculated by setting up nonlinear constraints for the derivatives, assuring a monotonically decreasing behavior for the function. The performance of the model was compared with five other models commonly used in industries and process simulation programs and is found to provide better accuracy in comparison when working with polar fluids. Further, its performance is found to be comparable to some models when estimating nonpolar and light fluids. The statistical analyses used to verify the performance of the model in comparison with the other models used in literature include the calculation of the r-squared, adjusted r-squared, predicted r-squared, absolute average deviation, root mean square errors, and by visual inspection. The study also included the determination of thermodynamically consistent parameter values for twenty different fluids commonly used in process simulations.","PeriodicalId":13949,"journal":{"name":"International Journal of Chemical Engineering and Applications","volume":"9 1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74608663","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A study on the biogas production and the analysis of biogas-producing bacteria in natural zeolite and activated carbon-based media have been carried out. This research was aimed to find out the effect of solid media addition and to identify the bacteria species involved in biogas production under the anaerobic condition. The bacterial culture was carried out in batch anaerobic digesters for a 35-day incubation period. Three different composition of ring-shaped packing consist of natural zeolite (Z), activated carbon (K), and an equal mixture of natural zeolite and activated carbon (C) were added in an anaerobic reactor. Biogas as the product was analyzed with GC-TCD. Each of the bacteria’s DNA in the media then isolated, amplified, and also purified to find out the intensity of each DNA band. Sequencing process was conducted for each purified DNA bacteria and the sequence result then translated by BLASTn program in the gene-bank NCBI. The highest methane concentration of 34.32% was obtained from reactor with natural zeolite media, then the mixed media added reactor provided biogas with 26.31% methane and the last reactor with activated carbon media showed the smallest value of 20.77% of methane. Sequencing result shows that Dictyoglomus thermophilum species was dominated on the surface of K-packing, Rhodopseudomonas palustris species was observed on the C-media, and Thermococcus litoralis was living on Z-media. SEM image was taken to confirm the results of DNA identification.","PeriodicalId":13949,"journal":{"name":"International Journal of Chemical Engineering and Applications","volume":"307 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86816702","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The nanometric pristine MoO3 films were prepared from the 10 -2 M.L -1 solution of ammonium molybdate tetrahydrate [(NH4)6Mo7O24,4H2O] in distilled water. Co-doping at 0.5, 0.75 and 1% was obtained by adding cobalt (II) chloride hexahydrate (Cl2CoH12O6) in the pristine solution. The structure and the morphology of the films were investigated by X-ray diffraction and atomic force microscopy. Two pronounced (020) and (040) peaks corresponding to the orthorhombic structure phase of α-MoO3 were detected. The AFM observations showed the formation of micro-plates parallel to the surface plane with a roughness ranging from 33 nm to 54 nm. Optical properties were investigated through reflectance, transmittance and photoluminescence measurements. The optical band gap, the Urbach energy and the refractive index were deduced from these measurements. The presence of oxygen vacancies were revealed from the interband transitions in the blue and green domains. Co-doped MoO3 nanofilms showed ferromagnetic behavior. Photocatalytic degradation of aqueous solution of methylene blue (MB) under UV irradiation in the presence of Co-MoO3 nanofilms has been carried out using UV-visible spectrometer by monitoring the absorption of the solution of MB. The intensity of the absorption peak recorded toward 660 nm was deceased with the increase of the UV-illumination time and the color of the initial MB solution was drastically degraded.","PeriodicalId":13949,"journal":{"name":"International Journal of Chemical Engineering and Applications","volume":"90 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90626927","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
