“…The production of aromatics was promoted by catalysis and the effect of catalysis was stronger when the catalyst dosage was higher. This result is in good agreement with the reports of previous studies that acid sites are required to produce aromatics during biomass pyrolysis [4,5,7,9,16]. BTEX are very important raw materials in the petrochemical industry.…”

“…Pyrolysis with the biomass-to-catalyst ratio of 1:1 ( Figure 6) promoted the production of low-molecular-mass phenolics to a large extent, while high-molecular-mass phenolics were increased or decreased depending on the species. This result is attributed to promoted decomposition of lignin to phenolics and of high-molecular-mass phenolics to low-molecular-mass phenolics or aromatics owing to deoxygenation (dehydration, decarbonylation, and decarboxylation) and cracking occurring on the acid sites of the catalysts [7,18]. When the catalyst dosage was increased further (Figure 7), the conversion of high-molecular-mass phenolics to low-molecular-mass phenolics was more evident.…”

“…Naphthalene is regarded as a high-value-added chemical because it can be widely used as a raw material for producing a number of chemical products, such as synthetic resin, pesticide and dye [7]. PAHs were not produced from non-catalytic pyrolysis and from catalytic pyrolysis with the biomass-to-catalyst ratio of 1:1.…”

“…Zeolite is an aluminosilicate material containing micropores. Having acid sites in its pores, zeolite is widely used in catalytic pyrolysis of biomass [6,7]. In a couple of previous studies, we reported the results of non-catalytic and catalytic fast pyrolysis of SBEP wild reed [8,9].…”

Fast catalytic pyrolysis of wild reed was carried out at 500˝C. Waste fluidized catalytic cracking (FCC) catalyst disposed from a petroleum refinery process was activated through acetone-washing and calcination and used as catalyst for pyrolysis. In order to evaluate the catalytic activity of waste FCC catalyst, commercial HY zeolite catalyst with a SiO 2 /Al 2 O 3 ratio of 5.1 was also used. The bio-oil produced from pyrolysis was analyzed using gas chromatography/mass spectrometry (GC/MS). When the biomass-to-catalyst ratio was 1:1, the production of phenolics and aromatics was promoted considerably by catalysis, whereas the content of oxygenates was affected little. Significant conversion of oxygenates to furans and aromatics was observed when the biomass-to-catalyst ratio of 1:10 was used. Activated waste FCC catalyst showed comparable catalytic activity for biomass pyrolysis to HY in terms of the promotion of valuable chemicals, such as furans, phenolics and aromatics. The results of this study imply that waste FCC catalyst can be an important economical resource for producing high-value-added chemicals from biomass.

The biomass thermochemical conversion process includes two major approaches: pyrolysis and gasification. The advantages of pyrolysis and gasification of biomass feedstock in the presence of various catalyst systems are critically reviewed. The role of a catalyst in pyrolysis of biomass and its major components cellulose, hemicellulose and lignin is investigated. The discussion is focused on elucidating the reaction mechanisms involved in the formation of aromatics and phenols during catalytic pyrolysis. The pyrolysis performance of two major catalyst systems, metal-containing catalysts and zeolite catalysts, is analyzed. The impact of the catalyst on the deoxygenation efficiency is ascertained. In the catalytic gasification process, two major catalyst systems including alkali metals and noble metal catalysts are employed. This review illustrates the function of the catalyst in improving the yields of syngas and hydrogen and the mechanistic aspects of the reduction of tar and char formed during gasification. Ultimately, the review is intended to introduce the state of art in the biomass thermochemical conversion with an emphasis on the importance of the catalyst in producing value-added products.
