论文摘要
提出了一个一维的固定反应器模型，以描述用空气和蒸汽的气态碳氢化合物燃料通过自热重整（ATR）（ATR）和催化部分氧化（CPO）的催化转化。该模型定义了反应器中的两个后段，即上游氧化部分和下游改革部分。在氧化部分中，所有氧气都会转化，并部分转化燃料。经验燃料利用率用于量化燃料的哪一部分在氧化部分转换为空气和蒸汽相对流的函数。在氧化部分中，气温在与改革截面的交叉点上迅速朝向上层。在本节中，温度降低，而燃料则以水为氧化剂进一步转化。对于甲烷作为燃料，给出了模拟结果并将其与实验进行比较。对于多组分燃料，例如天然气和石脑油，描述了如何应用两部分模型。
A one-dimensional and stationary reactor model is presented to describe the catalytic conversion of a gaseous hydrocarbon fuel with air and steam to synthesis gas by autothermal reforming (ATR) and catalytic partial oxidation (CPO). The model defines two subsequent sections in the reactor, namely an upstream oxidation section, and a downstream reforming section. In the oxidation section all of the oxygen is converted, with partial conversion of the fuel. An empirical fuel utilization ratio is used to quantify which part of the fuel is converted in the oxidation section as function of the relative flows of air and steam. In the oxidation section, the gas temperature rapidly increases toward the toptemperature at the intersection with the reforming section. In this section the temperature decreases while the fuel is further converted with water and CO2 as oxidant. For methane as fuel, simulation results are presented and compared with experiments. For multicomponent fuels such as natural gas and naphtha, it is described how the two-section model can be applied.
