These reactions increase the probability of incomplete combustion and are more likely to release uncombusted and photochemically active hydrocarbon compounds into the atmosphere.

这些反应增加了不完全燃烧得可能性并且易于放出未燃烧的，易起光化反应的碳氢化合物释放到大气中。

The main objective of this research project is to modify the Methyl-Acetylene/propadiene selective hydrogenation reaction system of the No.3 Naphtha Cracker in CPC. The original gas phase reaction system was redesigned to a liquid phase reaction so that higher propylene selectivity was achieved and lower rates of propane and green oil were produced. To recover effectively the higher production of valuable propylene from the reaction system, the following fractionator was also redesigned.

本研究之目的在於修改中油公司三轻工场老旧的甲基乙炔／丙二烯选择性氢化气相反应系统，使成为液相反应系统，藉由液相反应的优异性，提高由MAPD氢化得到丙烯之选择率，同时降低丙烷及绿油产率，以增加丙烯产率，另亦修改丙烯精馏系统，以提升蒸馏塔提纯之效率。

In the thesis a series ofβ-pyrazolyl-α,β-unsaturated Fischer carbene complexes were synthesized and structurally characterized by NMR, IR and X-ray crystallographic determinations. Based on the dynamic nuclear magnetic resonance and density functional calculation results, a three-step mechanism is proposed for the Michael type addition of pyrazoles to the alkynyl carbene complexes.
