【Abstract】 Effects of thermal crack of n-butane on its steam reforming reaction are researched.The n-butane setam-reforming without catalysts is carried out in a continuous flow fixed-bed reactor.The effects of reaction temperature and S/C on thermal crack of n-butane are investigated.The results show that n-butane cracked thoroughly at 750 ℃ which is the optimum temperature for catalystic activity tests of n-butane steam reforming.The gas yield,C₁ selectivity and n-butane conversion decreases with the S/C increases.更多还原
