AbstractIsothermal experiments on C3H8, with or without water, in fused silica capillary capsules were conducted at temperatures (Ts) between 300 and 400 degrees C for durations up to 322hours. Reaction progresses were evaluated with Raman spectroscopy at room T before and after heating. After an initial experiment, some samples were reheated to the same T for total durations up to 821hours. Consumption of water was monitored by calculating the changes in relative volumes of the vapor, aqueous, and C3H8 liquid phases from the lengths of the phases in the capillary. Reactions of C3H8 without water produced a small amount of CH4, reaching a steady state after about 100hours of heating at T<360 degrees C. Reactions with water appear to be largely hydrolysis, generating a CH4-rich vapor phase and methanol and ethanol in the aqueous phase. At fixed T, Raman spectra showed that concentrations of alcohols increased steadily with time as water was consumed. Our observations show that, without iron-bearing mineral buffers, the reactions between propane and water are relatively limited, forming alcohols without further oxidation to propanoic or ethanoic acid and/or CO2. This observation suggests that during deep burial, hydrocarbon gases may be more stable in iron-poor reservoirs like quartz arenites or carbonate grainstones than in mudstones or arkoses that are rich in redox-reactive iron-bearing siliciclastic and diagenetic minerals.
