摘要

本研究係利用氫化技術，以植物油與含硫柴油作為雙進料，透過共製程摻煉方式，同時進行氫化脫氧與氫化脫硫反應，於產品不需另外混摻的前提下，直接生產所需比例之綠色柴油。實驗以大豆油與未脫硫之石化柴油作為主要料源進行測試，變化不同實驗參數，如氫氣/植物油進料比例、液體空間流速、反應溫度、反應時間、反應壓力、觸媒填充方式…等，觀察其對於氫化共製程摻煉生產綠色柴油之影響。透過化驗分析協助，了解氣相產物尾氣組成，以及液相產物綠色柴油之成分結構、氧含量、硫含量…等油品性質。結果顯示氫化脫氧具有相當成效，能將植物油有效轉化成綠色柴油；然而氫化脫硫則受到反應器之限制，效果不如預期。但綜合實驗結果顯示，推測在反應器體積足夠與適當反應條件的情況下，應可同時進行氫化脫氧脫硫的共製程摻煉反應，直接合成所需比例之綠色柴油，不需再另外透過產品摻配的處理程序。

This investigation focused on producing Green-Diesel through hydroprecessing technology. Green-Diesel would be directly obtained from the deoxygenation and desulfuration coprocessing, as feeding with soybean oil and sulfur diesel. The influence of this process was studied by varying experimental parameters, such as H_2/oil ratio, liquid hourly space velocity (LHSV), temperature, pressure, catalyst loading … etc. The analyzing results indicated the composition of tail gas and the properties of Green-Diesel, including composition, oxygen and sulfur content. The deoxygenation reaction indeed works, and the vegetable oil is transformed to Green-Diesel successfully. However, the desulfuration reaction was not as good as expectation. It was supposed that the deoxygenation and desulfuration reaction would well work at the same time under co-processing and the desired proportion of Green-Diesel would be produced without further mixing, if the size of reactor was large enough and also under suitable operation conditions.
