本研究著重在實驗室自製加氫可再生柴油(HRD)應用在柴油引擎中排放氣體的影響。在實驗中採用純傳統柴油(D100)、20 %生物柴油(B20)和20 %HRD(H20)等三種燃料，分別探討在不同轉速和不同扭矩下的排放特性。研究柴油引擎中CO、CO2、HC、NOX、黑煙不透明度、甲醛、乙醛、苯、甲苯、二甲苯的排放變化。而為了保持HRD的質和量，進行加氫處過程催化劑再生實驗。跟據排放分析，與D100和B20相比，HRD有效降低了CO、CO2、NOX、黑煙不透明度、甲醛、乙醛、苯、甲苯、二甲苯的排放量。

The application of hydro-processed renewable diesel (HRD) was proposed in this study, in associate with the emissions from a turbo-charged diesel engine under steady-state operation. This study investigated the regular and irregular emissions including CO, CO2, HC, NOx ,smoke, formaldehyde, acetaldehyde, benzene, toluene and xylene from diesel engine with feeding pure petro-diesel (D100), 20 % blending of HRD (H20) and 20 % blending of biodiesel (B20) at various engine speeds and loads. For maintaining the quality of the fuel, the catalyst regeneration for the HRD production process was firstly performed. According to the emission analysis, the addition of HRD by 20 % reduced the emissions of CO, CO2, NOx, smoke, formaldehyde, acetaldehyde, benzene, toluene and xylene compared to D100 and B20. The HC emissions from H20, which were higher than the ones from D100 and B20, can be further reduced by improving the hydro-processing technology for producing higher quality of HRD.
