The syngas production by partial oxidation using a homogeneous charge compression ignition engine

摘要

It is essential to develop the environment-friendly alternative energies urgently considering the limited fossil fuel and the global warming caused by environmental destruction.In this research,the new technology was studied to produce syngas from methane or simulated biogas with a HCCI reforming engine.The purpose is to provide the basics for the research on biogas treatment mainly comprising of methane and carbon dioxide,the cause of global warming.This experiment was conducted on the changes in syngas concentration according to the variations of oxygen/methane ratio,total flow rate,intake heating temperature,CO2 in mixture and oxygen enrichment with partial oxidation.Through the parametric screening studies,optimum conditions and their results in this study was taken as follows;The maximum content of syngas was;27.4% at 0.3 of oxygen/methane ratio,32.38% at 117.3 L/min of total flow rate,and 35.83% at 355 °C of intake heating temperature.41.06% of syngas was produced at 50.33% of oxygen enrichment ratio.
