生物質(zhì)催化要完蛋了,甲烷重整要火 已有8人參與
|
|
據(jù)美國NSF可靠消息,NSF一準備大量減少資助生物質(zhì)項目,轉(zhuǎn)而資助甲烷項目,先知先覺的兄弟們趕緊逃逸,早點轉(zhuǎn)行。 看著兩篇文章,一篇講十字路口的生物質(zhì)轉(zhuǎn)化,一篇講分子篩用于甲烷轉(zhuǎn)化,而不是生物質(zhì)轉(zhuǎn)化。 http://pubs.rsc.org/en/content/articlepdf/2014/gc/c4gc90001d http://pubs.acs.org/doi/pdfplus/10.1021/cm401119d |

不清楚樓主為什么要故意誤導(dǎo)大家?Paul J. Dauenhauer and George W. Huber的文章只是Green Chemistry的專輯的引言,對于生物質(zhì)的發(fā)展呈現(xiàn)的是絕對的正面的意見。大家可以看看附件的文章內(nèi)容,自己做出評斷。 第二篇文章與甲烷的轉(zhuǎn)化沒有絲毫關(guān)系,這里是文章的摘要: A dual template synthesis strategy was employed to achieve one-step design of meso- and microporous MFI nanosheet assemblies with tailored morphology, mesoporosity, and catalytic activity. A molecular template (tetrapropylammonium hydroxide, TPAOH) and a polyquaternary ammonium surfactant ([C22H45–N+(CH3)2–C6H12–N+(CH3)2–C6H13]Br2, C22–6–6) were used as cotemplates in the synthesis with a composition of 30Na2O/1Al2O3/100SiO2/10C22–6–6/xTPAOH/4000H2O/18H2SO4. By tuning the concentration of TPAOH (x) from 0 to 20, the morphology of the as-obtained MFI nanosheet assemblies changed from intertwined, to house-of-cards-like, and to dense packing plates. The N2 isotherms showed the hysteresis loop at the range of P/P0 = 0.45–1.0 increases, reaches a maximum, and then decreases with increasing x values, indicating a systematic tailoring of the mesoporosity with TPAOH concentrations. Under strict kinetic control, the rates and apparent activation energies of the ethanol activation in zeolite nanosheet assemblies were comparable. The catalytic conversion of benzyl alcohol in mesitylene showed that the activity of as-obtained MFI zeolites increases, reaching a maximum, and then decreases with increasing x values. The consistency in the variation of morphology, mesoporosity, and catalytic activity with varying x values in the synthesis indicates TPAOH can be used as a secondary template to tailor the textural and catalytic properties of MFI nanosheet assemblies primarily guided by C22–6–6. |
