The present study was designed to evaluate gasification performances of various corn kernel varieties (field corn, non-genetically modified (non-GMO) field corn, yellow field corn, white field corn and popcorn) for hydrogen gas production by aqueous-phase reforming (APR) using activated carbon supported platinum catalyst.

Corn kernels were solubilized in 200°C-subcritical water medium under 13.79 MPa CO₂ pressure before use. The hydrolysates obtained from hydrolysis process were rich in total organic carbons (TOC) with a 5200–5850 mg/L concentration range. There were significant differences among varieties in terms of overall solubilization. However, hydrolysates from different corn varieties produced the same amount of hydrogen gas with a yield of 130 mL/g corn on average. The gas chromatography-mass spectrometry (GC-MS) analysis of corn hydrolysates showed considerable decreases in the peak areas after APR compared to initial hydrolysates. These decreases indicate consuming most of the corresponding organics in the gasification process. Evaluation of gasification results based on carbon balance showed that only small fractions of organic carbons converted to carbon-containing gaseous products (CO and CO₂) and remaining carbons were precipitated as ungasified solid residue. Thus, gas mixtures produced from corn kernel hydrolysates were mostly composed of hydrogen as found in gas analysis.

本研究旨在评估通过水相重整制氢的各种玉米籽粒（田间玉米，非转基因（non-GMO）田间玉米，黄田玉米，白田玉米和爆米花）的气化性能。使用活性炭负载的铂催化剂。

将玉米粒溶于13.79 MPa CO _2的200°C亚临界水介质中使用前压力。从水解过程中获得的水解产物富含5200-5850 mg / L的总有机碳（TOC）。品种之间在整体增溶方面存在显着差异。但是，来自不同玉米品种的水解产物产生的氢气量相同，平均玉米产量为130 mL / g。玉米水解产物的气相色谱-质谱（GC-MS）分析显示，与初始水解产物相比，APR后的峰面积明显减少。这些减少表明在气化过程中消耗了大多数相应的有机物。基于碳平衡的气化结果评估表明，只有一小部分有机碳转化为含碳气态产物（CO和CO ₂），剩余的碳沉淀为未气化的固体残留物。因此，如在气体分析中发现的那样，由玉米仁水解产物产生的气体混合物主要由氢气组成。
