Steel slag-enhanced reforming process for blue hydrogen production from coke oven gas: Techno-economic evaluation

Technical alternatives for coke oven gas utilization in China: A comparative analysis of environment-economic-strategic perspectives

“…Here, r referred to the discount rate, NCF t denoted the cash flow in the t th year, and the expected plant lifetime was T . Additionally, equation (9) was utilized to determine the internal rate of return (IRR) [ 34 ], which is the discount rate at which the NPV equals zero [ 11 ]. The calculation of IRR involved C 0 , which represented the total initial investment costs.…”

Research progress of hydrogen production and CO2 fixation in molten slag cooling process

“…Reproduced with permission: Copyright 2022, Elsevier. [51] | 447 The comprehensive analysis of operating parameters and economic competitiveness of hydrogen production from coke oven gas reforming showed that the best effect was achieved when the temperature was 600°C and the molar ratio of steel slag to coke oven gas was 1.0. The conversion efficiency of CH 4 exceeded 99.33%, and the fixation rate of CO 2 exceeded 98%.…”

“…When the reaction temperature was above 900°C, the adsorbent CaCO 3 could be completely regenerated. [51] In this study, a new sorption enhanced chemical looping reforming (SE-CLR) process based on steel slag is proposed, it is expected to achieve efficient carbon capture while reducing the cost of hydrogen production. A schematic diagram of SE-CLR process is shown in Figure 8.…”
