The percentage of (H2+CO) and the ratio of H2/CO in the reducing gas are important parameters for the COG reforming. In the present work, the pyrolysis reactions of COG with O2, H2O, and CO2 were thermodynamically calculated and analyzed. The calculation results show that, (1) as only one kind of agent (O2, H2O, CO2) participate the reaction, when pyrolyzed with H2O or CO2, the percentage of (H2+CO) in the reducing gas was highest, and were 95.26%. The H2/CO in the reducing gas was highest when pyrolysis with H2O and was 3.73. (2) as two kinds of agent participate the reaction, the percentage of (H2+CO) in the reducing gas obtained by pyrolysis decreases with the proportion of O2 in the mixed gas increases. The H2/CO ratio in the reducing gas gradually decreases with increasing pyrolysis temperature. (3) in the ternary calculations of COG reforming, when the proportion of O2 is higher, the percentage of (H2+CO) is lower. When the proportion of H2O is higher and the proportion of CO2 is lower, the ratio of H2/CO is higher. The research contents and results may provide the theoretical guidance on the optimizing the COG reforming process and selection of pyrolysis agents for the development of the relative chemical and metallurgical industry.","PeriodicalId":11899,"journal":{"name":"Environmental Technology and Innovation","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136093224","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}

These factors restrict its widespread use in agriculture and forestry. In this study, a new type of super absorbent polymers (AD-SAP) with low residual acrylic acid and sodium ions was synthesized by using ammonia solution instead of strong alkali sodium hydroxide for neutralization and adding modified diatomaceous earth to improve the grafting efficiency. The prepared samples were characterized by Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), and energy-dispersive X-ray spectroscopy (EDS), and the influence of the dosage of acrylic acid and ammonia solution used for preparation on the residual content of water-soluble harmful components in AD-SAPs was investigated. When 28% of acrylic acid, 24% of ammonia solution, and 5% of diatomaceous earth were used for synthesis, the residual acrylic acid content in AD-SAP was 0.03%, and the sodium ion content was reduced to 0.12 g/kg, which is much lower than the three commercially available SAPs. However, its water-absorption capacity has not decreased and its salt resistance has improved. The water absorption ratio of AD-SAP is 578g/g, and the salt-absorption ratio is 87 g/g. Pot experiments showed that AD-SAP eliminated the adverse effects of commercial SAPs on crop growth. The research provided technical support for the production of SAPs, and offer scientific guidance for how to mitigate the adverse effects of SAPs on crop growth.","PeriodicalId":11899,"journal":{"name":"Environmental Technology and Innovation","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135809638","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}
