China, as the world s biggest producer and exporter of metallic magnesium, produces metallic magnesium in its western provinces through the silico-thermic process known as the Pidgeon process. However, there are few metallic magnesium plants in eastern China, especially in Liaoning province where magnesite is rich in reserves. The short supply of magnesium has limited the growth of the magnesium casting industry and the local magnesite industry. Under the carbon market established to face the challenges of climate change, how to choose an economical and feasible route for magnesium production, is a key factor to determine the development of magnesium industry in Liaoning. In this paper, life cycle analysis models are developed to study the energy consumption, greenhouse gas (GHG) emissions, and economics from cradle to gate for six different metal magnesium production processes using data accounting for different geographical environments, process equipment, and energy supply pathways based on the Chinese Life Cycle Database (CLCD). The influence of carbon trading prices on economic performance of the six processes is also investigated. Compared with the current process widely used in China, the new magnesium production technology using Liaoning s abandoned magnesite as raw material and the coke oven gas from steelworks as fuel showed the best economic performance in terms of cost for greenhouse gas emissions.","PeriodicalId":52958,"journal":{"name":"Carbon Resources Conversion","volume":"159 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":"135760562","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, aqueous NaCl electrolytic system was used to oxidize Zhaotong lignite to prepare BPCAs. The electrochemical oxidation of lignite in aqueous NaCl solution could produce more BPCAs than that in aqueous NaOH solution. The aqueous NaCl electrolytic system could in-suit produce a stable OCl−, which was synthesized by the combination reaction between Cl2 and OH− generated in the anode or cathode, respectively. The in-suit produced OCl− would degrade the organic structures of the lignite dispersing in the electrolyte to generate BPCAs. The formation of BPCAs could be greatly affected by current density, electrolysis time and the addition amount of NaCl in the electrolytic system, which resulted from that the factors played an important role in the generation of OCl−.

SA modification improved the hydrophobicity without affecting the morphology and crystal structure of MOF. Adsorption of FDH on the modified MOF (SA@HKUST-1) was compared to that of the native HKUST-1 and ZIF-L. The adsorption kinetics on all MOFs was found to follow pseudo-second order kinetics and the isotherm was best described by Freundlich model. The high stability of SA@HKUST-1 and enhanced hydrophobic interaction between support and CO2 resulted in high catalytic efficiency and stability of FDH@SA@HKUST-1. The immobilized enzyme retained 95.1% of its initial activity after 4 cycles of repeated use. It was also shown that FDH@SA@HKUST-1 retained morphology and crystal structure after repeated use.
