    摘要:

    利用感應(yīng)加熱原理,設(shè)計(jì)并建立了基于感應(yīng)加熱的流化床生物質(zhì)氣化制氫試驗(yàn)裝置,從反應(yīng)器內(nèi)部為生物質(zhì)氣化過(guò)程提供熱量,實(shí)現(xiàn)了準(zhǔn)確控溫下的生物質(zhì)氣化制氫。以稻殼為生物質(zhì)原料,水蒸氣和空氣為氣化劑,進(jìn)行了生物質(zhì)氣化制氫試驗(yàn)研究,考察了反應(yīng)溫度、蒸汽與生物質(zhì)的質(zhì)量比(S/B)、當(dāng)量比(ER)對(duì)產(chǎn)物氣成分和產(chǎn)氫率的影響。試驗(yàn)結(jié)果表明:氣化溫度在800℃時(shí),H2體積分?jǐn)?shù)隨著S/B增大或ER減小而升高,H2產(chǎn)率在S/B為1.5或ER為0.22存在最大值。在溫度為950℃、S/B為1.5、ER為0.22時(shí),H2體積分?jǐn)?shù)和產(chǎn)率同時(shí)達(dá)到最大值35.47%和78.22 g/kg。

    Abstract:

    Based on electromagnetic induction heating technology, a fluidized bed gasification reactor based on induction heating was manufactured. It could provide heat for the biomass gasification process from the inside, and control the gasification reaction temperature accurately. Taking rice husk as raw materials of biomass, steam and air gasification as gas agent, biomass gasification for hydrogen production experiment was carried out. The effects of reactor temperature, steam to biomass ratio (S/B), and equivalence ratio (ER) on gas composition and hydrogen yield were investigated. According to the experimental results, it was found that when the reactor temperature was 800℃, the hydrogen content increased with the increase of S/B or the decrease of ER, hydrogen yield reached its maximum at the S/B of 1.5 or at the ER of 0.22. The highest hydrogen content (35.47%) and the highest hydrogen yield (78.22g/kg), was achieved simultaneously at a reactor temperature of 950℃, ER of 0.22, and S/B of 1.5.
