    摘要:

    利用熱解-氣質(zhì)聯(lián)用儀對(duì)杉木進(jìn)行了分級(jí)催化熱解實(shí)驗(yàn)，考察溫度和催化劑對(duì)熱解產(chǎn)物組成和含量的影響,。結(jié)果表明第1級(jí)300℃熱解產(chǎn)物種類(lèi)較少,，以有機(jī)抽提物為主,，而第2級(jí)500℃熱解產(chǎn)物種類(lèi)較多,。ZSM-5和MCM-41兩種催化劑都降低了熱解產(chǎn)物中羰基化合物和大分子木質(zhì)素?zé)峤猱a(chǎn)物的質(zhì)量分?jǐn)?shù),。ZSM-5降低了熱解產(chǎn)物乙酸的質(zhì)量分?jǐn)?shù),，并形成大量芳香烴,；而MCM-41提高了熱解產(chǎn)物中乙酸和糠醛的質(zhì)量分?jǐn)?shù)。

    Abstract:

    Step-wise pyrolysis of fir was conducted in the presence of catalysts by using pyrolysis-gas chromatography/mass spectrometry (Py-GC/MS). The effects of catalysts and temperature on composition and content of the pyrolysis products were studied. The results showed that few types of the products were found in the first-step 300℃ pyrolysis and the main products were extractives, while a great variety of products were detected in the second-step 500℃ pyrolysis. ZSM-5 and MCM-41 could reduce the contents of carbonyls and macromolecular lignin derivatives. ZSM-5 catalyst was helpful to reduce the content of acetic acid, and produced lots of aromatic hydrocarbons in the pyrolysis products. The content of acetic acid and furfural in the prolysis products were obviously increased by the presence of MCM-41 catalyst. 
