摘要

以全钢型废旧轮胎为原料，通过热解、活化、浸渍、焙烧的流程制备了三种热解炭催化剂，分别为轮胎热解炭（Raw char）、轮胎热解活性炭（AC）和负载Zn的活性炭（Zn/AC）。采用N

吸/脱附、SEM、EDS、XRD等表征方法对催化剂进行了一系列表征和分析，发现CO

O活化可显著提高催化剂BET比表面积，最高可达380 m

，有效改善催化剂表面结构性质，同时浸渍法使催化剂表面负载大量ZnO活性位。对三种催化剂在纤维素热解焦油重整制氢过程中的催化性能进行了研究，发现Raw char（600℃）具有最佳催化效果，相较于空白组（500℃），热解气中H

体积分数提高了12.4%，达到19.3%，其次为Zn/AC（500℃）组的17.8%，实现了低温下催化纤维素焦油热解制得高产率H

Abstract

Three pyrolysis carbon catalysts were prepared by pyrolysis

activation

impregnation and calcination using all-steel waste tires as raw materials

namely Raw char

raw pyrolytic activated carbon (AC) and Zn modified activated carbon (Zn/AC). The catalysts were characterized by N

adsorption/desorption

SEM

EDS

XRD and other characterization methods. It was found that CO

O activation significantly increase the BET specific surface area of the catalyst up to 380 m

effectively improving the surface structure of the catalyst. Meanwhile

a large number of ZnO was loaded onto the surface by impregnation method. The catalytic performance of three catalysts was studied in the process of cellulose pyrolysis tar reforming to produce hydrogen. Results indicated that Raw char (600℃) has the best catalytic effect compared with the blank group (500℃). The volume fraction of H

in gas production increased by 12.4% to 19.3%

followed by 17.8% of the Zn/AC (500℃) group

which achieved high yield of H

by catalyzing cellulose tar at low temperatures.
