摘要

甲烷分解制氢被归类为蓝色绿松石,介于绿色和蓝色氢气之间。它不会产生温室气体(GHG)排放,也不需要安装碳捕获、利用和储存(CCUS)工艺,在各种技术中具有环境竞争力,因为唯一的副产品是固体碳。本研究采用实验设计(DoE)概念,通过 32 因子设计收集数据并确定重要因素,从而优化甲烷转化的温度和气体小时空间速度参数。考虑到反应的热力学平衡极限,在 900 K 和 6000 mL.h-1.g-1 条件下获得了最高的甲烷转化率。使用的催化剂通过 SEM、BET 和 XRD 进行了表征。

DoE-driven thermodynamic assessment of COX-free hydrogen production from methane decomposition

Methane decomposition for hydrogen production is classified as blue turquoise, an intermediate between green and blue hydrogen. It does not generate greenhouse gas (GHG) emissions and does not require installation of carbon capture, utilization, and storage (CCUS) processes, becoming environmentally competitive among technologies, as the only byproduct is solid carbon. This research contributes to optimize temperature and gas hourly space velocity parameters for methane conversion adopting design of experiment (DoE) concept to collect data and identify significant factors through a 32 factorial design. Highest methane conversion, considering thermodynamic equilibrium limit of reaction, was obtained at 900 K and 6000 mL.h−1.g−1. The catalyst used was characterized by SEM, BET, and XRD.
