Experimental data for the publication: Measuring spatiotemporal concentration and temperature profiles in a tubular fixed-bed reactor for CO₂ methanation
收藏资源简介：
This repository provides the experimental data underlying all figures in the publication “Measuring Spatiotemporal Concentration and Temperature Profiles in a Tubular Fixed-Bed Reactor for CO₂ Methanation.” The data were obtained from a profiling reactor using a nickel–alumina catalyst, with a mass spectrometer applied for gas-phase analysis, as thoroughly described in the publication. The data are organised as follows: For Experiments 1–4, steady-state and dynamic profiles are sorted separately. For the dynamic profiles, the cycle number and axial position are provided along with the corresponding gas-phase composition and temperature. From these datasets, Figures 2, 3, and 4 can be derived. The underlying data for Figure 5 are provided separately. List of experiments Exp.

本仓库提供了发表于论文《管式固定床反应器中CO₂甲烷化的时空浓度与温度分布测量》（英文原标题："Measuring Spatiotemporal Concentration and Temperature Profiles in a Tubular Fixed-Bed Reactor for CO₂ Methanation"）中所有配图的支撑实验数据。该数据集所用的实验数据采集自采用镍-氧化铝催化剂 (nickel–alumina catalyst) 的分布型反应器 (profiling reactor)，实验过程采用质谱仪 (mass spectrometer) 进行气相分析 (gas-phase analysis)，相关细节已在论文中详述。 本数据集的组织形式如下：针对实验1至实验4，其稳态分布 (steady-state profile) 与动态分布 (dynamic profile) 已分别归档。对于动态分布数据集，其包含循环编号、轴向位置 (axial position) 以及对应的气相组成 (gas-phase composition) 与温度信息。通过本数据集可推导得到论文中的图2、图3与图4；图5的原始数据已单独提供。 实验列表 实验编号 实验条件 关联文件 实验1 入口温度（T_in）= 593 K，流量=5.1 L/h Exp1_Steady_State.txt; Exp1_Dynamic.txt 实验2 入口温度（T_in）= 633 K，流量=5.1 L/h Exp2_Steady_State.txt; Exp2_Dynamic.txt 实验3 入口温度（T_in）= 673 K，流量=5.1 L/h Exp3_Steady_State.txt; Exp3_Dynamic.txt 实验4 入口温度（T_in）= 633 K，流量=10.1 L/h Exp4_Steady_State.txt; Exp4_Dynamic.txt
