Summary: The research presented in the paper focused on determining the content and mode of arsenic occurrence in Polish commercial coal, finding that arsenic in coal is mainly associated with mineral matter. The study also showed that the amount of arsenic passing to gas during combustion is influenced by the parameters of the combustion process and the chemical composition of the coals. Statistical analysis indicated that the presence of arsenic in coal, mainly in association with disulphides, carbonates, and sulphates, significantly influences the amount of Asgas in the flue gas.

Summary: This study aims to explore the correlation between selenium concentration and arseniasis in a high-arsenic coal area in southern Shaanxi Province, China. The results show that the arsenic and selenium contents in Ziyang County are higher than those in the control area. The arsenic content in the hair of arsenic-poisoned patients in Ziyang County positively correlates with the degree of arseniasis, while the selenium content in hair and urine negatively correlates with arseniasis. Selenium may accelerate the metabolism and elimination of arsenic and antagonize its toxicity.

Summary: This study measured the high-pressure adsorption isotherms of two coal samples to investigate the methane adsorption process and mechanisms in coal. The results showed that micropore filling and surface adsorption are the primary adsorption mechanisms for supercritical methane in coal, with micropore filling occurring in pores smaller than 1.1 nm and surface adsorption occurring in 1-2 nm pores. Micropore filling adsorption plays a significant role in the overall methane adsorption, and the nano-confined effect and low water saturation contribute to the enrichment of free gas in deep coalbed methane (CBM). These findings provide insights into the occurrence behavior of unconventional natural gas in reservoirs.
