摘要


微型甲醇-水電漿重組器,是將超音波震盪器震盪後的甲醇-水混合溶液的霧化微粒子,直接導入電漿內加熱,這些微粒子可以使化學反應接觸面積加大幾十倍以上,反應快速,電漿能量移轉產生的離子、電子、中子、自由基,可加快甲醇及水分子分解的反應,瞬間重組成氫氣、一氧化碳、二氧化碳和甲烷等氣體。 經不同電漿產生器的火星塞跳火間隙實驗結果顯示,本微型甲醇-水電漿重組器設備在跳火間隙為5mm、裝有40kV-500pF高壓電容的高密度電漿產生器以及83%濃度的甲醇水溶液,有最高之跳火電壓值約4kV,以及較理想的產氫效能約10.83%。

Micro particles of nebulized methanol-water solution was led into the plasma and heated within the micro-plasma methanol-water reforming, after it has been treated by ultrasonic mist maker by using the energy produced by the spark plug gap. Thanks to these micro particles, contact area of chemical reaction was dozens times enlarged, thus displayed fast reaction. Transference of plasma energy generated ions, electrons, neutrons, and free radicals which accelerated decomposition reaction of methanol and water molecules and then combined to form gases of hydrogen, carbon monoxide, carbon dioxide, and methane.The results of experiments of plasma generator showed that the equipment of plasma methanol reformer performed the highest spark voltage value of 4kV and higher content of hydrogen of about 10.83% with the setting of 5mm spark plug gap, 40kV-500pF of high-voltage capacitor, and methanol-water solution of 83% concentration.
