对20—400℃不同温度条件下褐煤和可溶的铀酰类物质之间的相互作用进行了实验研究。观察到褐煤能固着铀酰类物质(45—250℃),并使其还原成晶质铀矿(120—400℃)。由于褐煤对铀酰类物质的固着作用,结果形成了稳定的有机-铀酰化合物。褐煤对铀酰类物质的还原作用引起介质溶液中释放一定数量的H~+和造成褐煤的脱氢作用,这种脱氢作用可认为是两种不同性质的作用。第一种是醇官能团氧化成醛官能团或酮官能团并同时伴随铀酰类物质的还原作用。第二种是由铀造成的脂肪族烃类的脱氢作用,在这一过程中产生的呈分子状态存在的氢后来对铀酰类物质起进一步的还原作用。
The interaction between lignite and soluble uranyl species at different temperatures of 20-400 ℃ was studied. It was observed that lignite can fix uranyl species (45-250 ° C) and reduce it to crystalline uranium (120-400 ° C). As a result of the solidification of lignite to uranyl species, stable organic-uranyl compounds are formed. The reduction of uranyl species by lignite results in the release of a certain amount of H ~ + from the solution and the dehydrogenation of lignite. This dehydrogenation can be considered as two different properties. The first is the oxidation of alcohol functional groups to aldehyde functional groups or ketone functional groups, accompanied by the reduction of uranyl species. The second is the dehydrogenation of aliphatic hydrocarbons caused by uranium, and the presence of hydrogen in the molecular state in this process will later further reduce the uranyl species.
