摘要 利用高压釜对Fe2(SO4)3、Al2(SO4)3、MgSO4、CaSO4、Na2SO4及K2SO4等六种硫酸盐与正庚烷发生反应的可能性进行了热模拟实验。研究发现,400℃时Fe2(SO4)3、Al2(SO4)3和MgSO4都能与正庚烷发生强烈的硫酸盐热化学还原反应(TSR),主要生成金属氧化物和/或金属硫化物、硫化氢、炭以及硫醚、硫醇、噻吩等有机硫化物;而相同条件下CaSO4、Na2SO4及K2SO4参与TSR的程度则很低。根据六种硫酸盐与正庚烷反应后气油固三相产物的分析结果,探讨了硫酸盐热化学还原反应的基元步骤与反应机理。 Thermal simulation experiments on n-heptane and six sulfates including Fe2 (SO4 )3, Al2 (SO4)3, MgSO4, CaSO4, NazSO4 and K2SO4 were carried out in autoclave in the presence of water to investigate the possibilities of thermochemical sulfate reduction (TSR). It was found that Fez (SO4 )3, Al2 (SO4)3 and MgSO4 could intensely react with n-heptane at 400 ℃ to produce metal oxide and / or metal sulfide, hydrogen sulfide, coke and a series of organic sulfur compounds such as mercaptans, sulfoethers and thiophenes as the main products. Under the same reaction conditions, the extent of reactions of n-heptane with CaS04, Na2SO4 and K2SO4 is very limited. Based on the analysis of the gas-oil-solid 3-phase products of the reactions between n-heptane and six sulfates, the elementary steps and reaction mechanism of TSR were tentatively studied.
