Method for improving stability of hydrogen production by liquid alkane fuel reforming

The invention provides a method for improving stability of hydrogen production by liquid alkane fuel reforming, and belongs to the technical field of clean energy. The method comprises the following steps: firstly, grinding and activating a Ru/gamma-Al2O3 reforming catalyst, setting the pumping flow of a liquid alkane fuel and a small molecular alcohol solution according to a water-carbon ratio of 3.5, respectively vaporizing in an evaporation chamber, entering a fixed bed reactor, and carrying out reforming reaction under the catalytic action of the catalyst to obtain hydrogen-rich reforming tail gas; carbon deposition is inhibited, so that the service life of the reforming catalyst is prolonged, and long-term stable operation of steam reforming hydrogen production is ensured. 本发明提供的一种提升液态烷烃燃料重整制氢稳定性的方法，于清洁能源技术领域。本发明首先将Ru/γ-Al2O3重整催化剂研磨并活化，按照水碳比为3.5设置液态烷烃燃料与小分子醇类溶液的泵入流量，在蒸发室中分别汽化，进入固定床反应器，在催化剂的催化作用下发生重整反应，得到富含氢气的重整尾气。抑制积碳的产生，从而延长重整催化剂的服役寿命，保证水蒸气重整制氢的长期稳定运行。
