Acidic gas capture by traditional aqueous amine solution requires a plenty of energy for solvent regeneration. A phase-change capture system was considered to be a promising alternative because only the CO2-rich phase needs to be recovered and the CO2-lean phase can be reused directly without disposal, improving the energy utilization efficiency. Based on this principle, the phase-change absorption...
Crystallization behaviors of biodiesel including measurement and modeling the amount of precipitated crystal at different temperatures were studied. The amount of crystal precipitated from biodiesel at different temperatures was measured by differential scanning calorimeter (DSC) according to the method, which was established in this work. Comparison of model predictions and DSC experimental data...
Coal-fired power plant (CFPP) is one of the main sources of anthropogenic CO2 emissions. Capturing CO2 from CFPP by post-combustion process plays an important role to mitigate CO2 emissions. However, a significant thermal efficiency drop was observed when integrating CFPP with post-combustion carbon capture (PCC) process due to the steam extraction for capture solvent regeneration. Thus research efforts...
Carbon capture for fossil fuel power generation draws an increasing attention because of significant challenges of global climate change. This study aims to explore the integration of a 453MW e natural gas combined cycle (NGCC) power plant with an MEA-based post-combustion carbon capture (PCC) process and CO 2 compression train. The steady state models of the NGCC power plant, the...
p-Xylene is an important intermediate for the production of polyethylene terephthalate, it has growing chemical industrial demand based on the statistics in the last few decades. In the process of producing p-Xylene, gaseous hydrocarbon fuels (e.g., H2, C1–C3) are usually involved, which renders p-Xylene highly possible mix with those gaseous hydrocarbon fuels as leaking occurs, this presents fire...
A novel plate-type anodic alumina supported 17.9 wt% Ni/Al 2 O 3 /alloy showed a quick deactivation in daily start-up and shut down (DSS) steam reforming of methane (SRM) at 700°C, because of the Ni oxidation reaction with steam. When 0.078 wt% Pt was doped, the catalyst exhibited self-activation and self-regeneration ability, while 3000h continual and 500-time DSS stability was testified...
