Recently global warming caused by greenhouse gases has emerged as an important societal issue. In the long run, the era of hydrogen economy that produces and utilizes green-hydrogen from renewable energy sources will prevail the current fossil-fuel based energy system. Until the prevailing time of hydrogen economy, however, hydrogen should be at least blue-hydrogen in nature which requires removal of CO₂ in hydrogen generation steps. Blue hydrogen can be produced from low-grade fuels such as coal, petroleum coke and wastes with proper CO₂ removal processes. Converting low-grade fuels to hydrogen, it is essential to develop a gasification technology that produces syngas which
contains CO, CO₂ and hydrogen. Gasification is one of the most important technologies in the blue-hydrogen production process. In this study, petroleum coke in slurry phase was gasified in the 2 ton/day capacity test unit. Gasification results yielded carbon conversion of about 93% and cold gas efficiency of about 60%. Based on the pilot-scale test results, it was predicted that the cold gas efficiency of about 72% could be secured in the 10-times bigger 20 ton/day demonstration-scale gasification system. The prediction procedure based on the energy balance calculation for the scale-up design as well as on the simulation results at chemical equilibrium conditions was explained.
