摘要

为解决固体废物处理、处置过程中可再生能源的转化与废物的利用问题

本课题利用热裂解-色谱质谱联用仪(Py-GC/MS)研究分别以氧化石墨烯与石墨烯分散液为原料制备Ni改性石墨烯对生物质热解产物的影响。结果显示:改性石墨烯促进了纤维素热解主要产物1

6-脱水吡喃葡萄糖的生成

随负载量增加效果更明显;C1—C4烃类产率受改性石墨烯影响很大

C5—C8烃类产率略有提高;经改性石墨烯催化木质素热解产物中酚类产率明显提高

经6%Ni-GO催化酚类产率达最大;醇类产率下降

酚类产率上升表明改性石墨烯对羟基的脱除与重组具有一定影响。此外

改性石墨烯还促进了结构较为简单的长碳链产物生成。

Abstract

To solve the problem occurs during renewable energy conversion and waste utilization in the process of solid waste treatment and disposal

the effect of Ni-modified graphene on pyrolysis products components of typical combustible solid waste were studied

by pyrolysis-chromatography mass spectrometry(Py-GC/MS). Graphene oxide and dispersion liquid of reduced graphene oxide were selected for preparation of catalysts. The results show that

the modified graphene promoted the formation of 1

6-dehydrated glucose

the main product of cellulose pyrolysis

and the effect was more obvious with the increase of the loading amount. The modified grapheme gave higher selectivity toward C1—C4 hydrocarbons and slightly to C5—C8 hydrocarbons. Catalyzed by the modified grapheme

lignin produced more phenol during pyrolysis

and the yield of phenol reached the highest when adding 6%Ni-RGO. The yield of alcohols decreased

while the yield of phenols increased

indicating the modified graphene played a certain role in removal and recombination of hydroxyl groups. In addition

the modified graphene promoted the production of long carbon chain products with simple structure.
