To mitigate the hazards of slagging in the actual production of coal and water hyacinth co-combustion for power generation, combined with slagging discrimination indices, X-ray fluorescence (XRF) and X-ray diffraction (XRD) were applied to study the effects of mixing ratios, temperature, and additives on the slagging characteristics of water hyacinth mixed anthracite combustion. At higher ashing temperatures, the K and Cl content in the ash was reduced, which helped to reduce slagging. CaO can compete with the fuel’s K and react preferentially with Si and Al, leading to reduced production of KAlSiO4 and KAlSi3O8. Kaolinite can weaken the function of K as a Cl carrier, allowing K to form complex potassium aluminosilicates with Si and Al. According to the comprehensive analysis of six ash sample slagging indexes, water hyacinth ash is serious slagging, anthracite ash is medium slagging, and the co-combustion of water hyacinth and coal can change the degree of ash slagging to a certain extent. Kaolin has a better-mitigating effect than CaO in preventing the slagging of mixed ash. These findings provide a starting point for the combustion of aquatic biomass with coal.","PeriodicalId":779,"journal":{"name":"Solid Fuel Chemistry","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2023-08-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"4152801","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Fourier transform infrared results showed that the humic acid samples obtained through precipitation with different strong acids were different from the humic acid standard in terms of the functional group content. Fluorescence spectroscopy showed that the humic acid extracted by HNO3 and H3PO4 had a lower fused ring and a simple molecular structure. In addition, the humic acid precipitated by HNO3 had the lowest E4/E6 ratio and highest molecular weight, along with an aromatic structure. The results showed that HNO3 is the best strong acid for the extraction of humic acid from biomethane fermentation peat residue by alkali extraction and acid precipitation.","PeriodicalId":779,"journal":{"name":"Solid Fuel Chemistry","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2023-08-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"4153475","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

XRD analysis of OSA showed that the main phases present were quartz and calcite in addition to structures like, pyrite, dioside, fluorapatite and muscovite. XRF analysis showed that increasing the ashing temperature to above 650°C accelerated the transformation reaction of calcite into lime. The transformation process was found to continue until the calcite phase completely disappeared at and above 850°C. The pH of the produced ash was found to be in the range of 9.4 to 12.18 based on ashing temperature. OSA with high pH value possessed alkaline properties and underwent alkaline reactions in contact with water. Performed mechanical properties tests indicated that Attarat OSA is a very rapid permeable material (>25 cm/h). Attarat OSA revealed low holding capacity ratio of water, which was estimated to be (3.8 g H2O/g ash), indicating high permeability and ability to percolate a leachate after contacting with water to other soil layers and consequently to the aquifer of underground water. It is worth mentioning that highlighting chemical composition and mechanical properties of Attarat oil shale ash will open the opportunity for its future reuse in various engineering applications as : catalyst, adsorbent, filler, additives and source of precious metals.","PeriodicalId":779,"journal":{"name":"Solid Fuel Chemistry","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2023-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"4729658","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Soot is produced as an unwanted product of biomass thermal degradation. Its nature and characteristics have been found to be biomass composition related for carbon related applications. In this study, the structural and chemical properties of soot samples from three (3) different biomass fuels from a low-temperature retort heating reactor were investigated. The samples were characterized using Scanning Electron Microscopy with Energy Dispersive Spectroscopy (SEM-EDS), Fourier Transform Infra-Red Spectroscopy (FTIR) and Branueur-Emmet-Teller (BET) method. Different structural patterns were observed for the soot samples (I1, I2, and I3) which were attributed to different biomass sources from which the samples were produced. Similar carbon contents (>70%) were measured for the samples as was found from the EDS analysis. Also, it can be inferred that O/C ratios of the three samples were < 0.6 making the samples sources of stable carbon. The FTIR analysis indicated that soot samples were rich in functional groups present in oxygenated hydrocarbons. The three samples had considerably high specific surface areas and porosities with pore sizes ranging from mesoporous (I1 and I2) to microporous (I3) as revealed by the BET results. These carbon-rich materials can be used as precursors to produce activated carbon and other carbon related materials.(Graphical Abstract)","PeriodicalId":779,"journal":{"name":"Solid Fuel Chemistry","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2023-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"4730785","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

When the oxygen concentration increased from 10 to 30%, the initial temperature, maximum mass loss rate temperature, and termination temperature decreased with the increase of oxygen concentration, but the mass loss rate increased from 17.25 to 17.69%, as well as when the gas flow rate increased from 30 to 100 mL/min, the termination temperature and mass loss rate increased, but the initial temperature decreased from 366.5 to 303.9°C.
