This study develops a simulation model for processing low-quality coal using ASPEN Plus software with an entrained flow gasification method, focusing on dry versus wet feeding systems. Entrained flow gasification is selected due to its capability to convert coal into synthetic gas (syngas) at high temperatures and pressures. The resulting syngas can be further purified to produce hydrogen, a clean and sustainable energy source. The simulation analysis key operational parameters—including temperature, pressure, and air-to-coal ratio—while comparing the performance of dry and wet feeders. These comparisons aim to assess the impact of each feeding method on gasification efficiency and hydrogen yield. The goal is to identify optimal conditions for maximizing hydrogen production from low-quality coal. Results from this study are expected to offer insights into the relative advantages of dry and wet feeding techniques in coal gasification. Furthermore, the findings will support efforts to design and operate more efficient gasification systems, helping to reduce dependence on conventional fossil fuels and contributing to global carbon emission reduction initiatives. Overall, this research contributes to the advancement of cleaner coal utilization technologies and the broader development of sustainable hydrogen energy systems.
