  10. It was still a technical problem on how to add the air to the reactor in so small pressure difference. in addition, the photocatalytic reaction efficiency was very low at the high speed. the reactor will be large, the price will be very high and the electricity will be enormously consumed during the photocatalytic - oxidation of h2s in the methane

    主要原因是沼氣中不含氧，使用時氣體流速大，壓差小，而用光催化氧化方法消除h _ 2s需要有相當量的氧參與，在壓差很小的情況下，一次空氣的加入存在技術困難；在高氣體流速條件下，光催化效率低，若用光催化方法消除h _ 2s ，反應設備龐大，耗電量高，價格昂貴，農民難以負擔。
