污泥残炭对城市污泥催化热解制油影响的实验研究
Experimental study on bio-oil obtained from municipal sludge pyrolysis catalyzed by char
摘要
Abstract
Pyrolysis of municipal sludge catalyzed by residue char was conducted in order to research the influences of the temperature and the proportion of char on the product yield and the component of the organic phase (OP).The results show that for non-catalytic pyrolysis,the yield of OP rea-ches a maximum of 6.83% at 500 ℃.Residue char is benifical to the removal of volatiles.Char benefits the hydrodeoxygenation and removal of chlorinated compounds,while it is negative to the reduction of PAHs (polycyclic aromatic hydrocarbons).Residue char was also treated with support-ing Fe,Cu,Al and Ni to study the catalytic effect of treated char.The results show that char sup-ported with Al favors the enhancement of HHV (higher heating value)and reduction of viscosity of OP.The contents of oxygenated compounds and nitrogen compounds decrease.The char supported with Fe is the best for hydrodeoxygenation and the reduction of viscosity of OP.Compared with the original carbon residue,the viscosity of OP catalyzed by char supported with Fe reduces by 24.32%while the content of hydrocarbons increases by 17.62%.Char supported with Ni helps decrease ni-trogen compounds.PAHs are not found in the OP catalyzed by char supported with Cu.关键词
