This study presents the multiple's effect technique, which is based on the reusage of different non, party and sorted municipal solid wastes (MSW), or biogas for syngas, converted into synthetic gasoline. The novelties of this technique include a basic multiple's effect parameter (MUW), which present a level of waste sorting, an effect of oxygen inhibition into different wastes, a simplified mathematical model and simulation with an Aspen Plus® simulator using the retrofitted methanol plan converted into the synthetic gasoline production. This technique includes a circular economy by using a circulated purified flue gas as raw material, co-products of hydrogen and water. This technique was tested on an existing methanol process, replacing natural gas with different alternatives of wastes or biogas for the synthetic gasoline production. The best alternative was the sorted MSW, which could generate an additional profit of 4.8 MEUR/a, including the garbage and CO2 emission reductions of 0.106·106 t/a and of 0.084 ·106 t/a.","PeriodicalId":7122,"journal":{"name":"Acta Chimica Slovenica","volume":"71 2","pages":"388-397"},"PeriodicalIF":1.2,"publicationDate":"2024-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141449295","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Under these conditions, adsorption sites of adsorbent were protonated primary and ternary amine groups of adsorbent shown as -NH3+ and -NHR2+, respectively, that adsorbed DC ions through electrostatic interaction. Adsorption isotherms of DC on GO/PAMAM4 were obtained under various ionic strengths, pHs and temperatures. Isotherms were analyzed by the ARIAN model. The highest observed adsorption capacity of this process was 246.7 mg g-1 at pH=0 and 318 K. Tests at pH=2 showed that this process was endothermic. Adsorption kinetic experiments were carried out under various initial DC concentrations, pHs, temperatures, shaking rates and ionic strengths and were analyzed by the KASRA model and intraparticle diffusion, ISO and NIPPON equations.

Then, Fe3O4 nanoparticles were synthesized by a simple hot water technique and composited with the nanofiber. The study focuses on applying the modified PVA nanofibers to remove malachite green (MG) from water using different pH, contact times, and dye initial concentrations. The surface morphology of the nanofiber was determined using SEM, FTIR, and XRD techniques. SEM showed that the crosslinking was increased, and Fe3O4 nanoparticles appeared as agglomerates on the surface of the nanofiber. The removal percentages at optimal pH and contact time were 99.76%, and 99.5%, respectively. Thereafter, kinetics was studied by the linear pseudo-first order, pseudo-second order, Elovich equation, and Intraparticle diffusion models. Results demonstrated that the adsorption kinetics follow the pseudo-second order. Moreover, the adsorption isotherm was discussed using Langmuir and Freundlich equations. The Langmuir equation best described the adsorption with R2 value of 0.9771, and the maximum removal was 128.205 mg/g. As a result, the MG dye molecules covered the PVA nanofiber/Fe3O4 nanoparticles in a monolayer and homogenous coverage. The results of this study are significant for industries' wastewater treatment as they provide a potential solution for the removal of MG dye from textile, paper, cosmetics, food, and aquaculture industries' wastewater.","PeriodicalId":7122,"journal":{"name":"Acta Chimica Slovenica","volume":"71 2","pages":"398-408"},"PeriodicalIF":1.2,"publicationDate":"2024-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141449260","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A Nanofiber mat consisting of Poly vinyl alcohol (PVA), nanoTiO2, and citric acid (PTC) was prepared using an electrospinning technique at a constant flow rate (0.5 ml/h). The morphology of the mat was detected using (FESEM) technique and image J software; they show that the mat has a Nanofiber morphology with an average diameter of 170 nanometers. This mat was used to remove methylene blue (MB) from water in two ways, the adsorption process and by photodegradation using UV light. The kinetic study of the adsorption of methylene blue MB on a PTC mat was carried out. results show that the pseudo-second order is best to describe the adsorption, of MB and the Intra- particle diffusion is the rate determining step. Seven isotherm models; four of two-parameters and three of three-parameters were used to examine the adsorption experimental data by applying linear and non-linear regression method using six error functions. The results showed comparable data between linear and non-linear regression methods for two parameters isotherms, and the best isotherm fitting with the data were Freundlich and Temkin models.
