本文介绍了液化石油气（LPG）、丁烷、丙烷、柴油和重质燃料油（HFO）在惰性多孔介质中的实验燃烧，以评估燃料精制的不同阶段内的合成气生产，考虑轻质气体直至渣油。多孔介质由氧化铝球固定床组成，在富燃料条件下产生稳定燃烧波的同时获得了温度和气体成分。该研究的结果表明，对于当量比phi = 1.3，可以部分氧化HFO，在产物中产生高达10%的H-2和CO，具有比本工作中测试的任何其他燃料更优越的上级性能。记录的温度结果的行为显示出良好的协议与现有的文献。对于使用液体燃料的实验，观察到燃烧波传播的上游区域，而对于phi > 2直到phi = 4，气体燃料呈现下游区域。结果表明，为了有效地将燃料转化为合成气，考虑到入口和出口处的化学能，在上游制度下操作反应器是方便的。此外，液体燃料，无论其精炼水平如何，都具有在惰性多孔介质中以有希望的体积生产合成气的潜力。版权所有（C）2016，氢能出版物有限责任公司。由爱思唯尔有限公司出版。保留所有权利。
Experimental combustion in inert porous media of Liquefied Petroleum Gas (LPG), Butane, Propane, Diesel Fuel and Heavy Fuel Oil (HFO) is presented to assess the syngas production within different stages of refinement of fuels, considering light gases up to a residual oil. The porous media is composed by a fixed bed of alumina spheres and temperatures and gas composition were acquired while stable combustion waves under rich fuel conditions were produced. The results of this study showed that it is possible to partially oxidize HFO producing up to a 10% of H-2 and CO in the products for the equivalence ratio of phi = 1.3, with a superior performance than any other fuel tested in this work. The behavior of the recorded temperature results showed good agreement with the available literature. Upstream regimes of propagation of the combustion wave are observed for the experiments with liquid fuels, while gaseous fuels presented downstream regimes for phi > 2 up to phi = 4. Results suggest that in order to efficiently transform the fuels into syngas, it is convenient to operate the reactor under an upstream regime considering the chemical energy at inlet and outlet. Furthermore, liquid fuels, regardless of its refining level, have the potential to produce syngas in inert porous media in promising volumes. Copyright (C) 2016, Hydrogen Energy Publications, LLC.
