Development of Novel Pyrolysis Technology Involving Chromium for the Measurement of D/H Ratios in n-Alkanes

A new pyrolysis technology involving chromium is proposed for the determination of δD in alkanes based on systematic analysis reaction temperature, conversion rate, and mechanism. Compared with traditional high-temperature (HTC) method, our findings suggest that chromium/high-temperature (Cr/HTC) can improve rate hydrocarbons reduce required temperature by up to 175 °C; meanwhile, increased an average 2.42% across entire analyzed range using Cr/HTC method. Changes wire itself were X-ray photoelectron spectroscopy (XPS); this facilitated understanding interaction mechanism between possible pathways catalytic process. The results show reacts hydrocarbons, capturing carbon as carbide (Cr2C3 CrC3) releasing hydrogen form H2. As progresses, resulting free accumulates surface or carbide, a marked reduction Cr/C ratio; these provide reliable evidence further application technology.
