“…The crude bio-oil was produced by fast pyrolysis of straw stalk in a circulating fluidized bed reactor with a capacity of 120 kg/h oil in our Lab [8]. In present work, the light fraction of the crude bio-oil was used, which was conducted by the distillation of the crude bio-oil up to 373 K at atmospheric pressure.…”

“…They proved that the feeds with higher H/C ratios favored to increase the yield of light olefins and reduce the coke. Our recent study also shows that light olefins can be selectively produced from bio-oil or biomass over the La-modified zeolites [8,28]. Furthermore, catalytic polymerization of light olefins has been industrially applied in petroleum refineries for producing fuels, and the synthesis fuels using olefins oligomerization could be suitable for utilization as engine fuels due to free of sulfur and other harmful impurities [29e35].…”

“…The major oxygenated compounds in the pyrolysis oil (Table 2) were acids, phenolic compounds, ketones, esters, aldehydes, and a few others. It is important to state that the conversion of most of these oxygenated compounds to OLP over the HZSM-5 catalyst was an indication of its ability to remove oxygen through complex reactions, such as deoxygenation, cracking, cyclization, aromatization, isomerization and polymerization reactions (Adjaye and Bakhshi 1995a;Gong et al 2011;Mentzel and Holm 2011). The low yield of OLP (about 6 to 13 wt%) might be attributed to the high water content of the sample (30%) and the char formation (about 18 to 22 wt%).…”

Catalytic Cracking of Pyrolysis Oil Derived from Rubberwood to Produce Green Gasoline Components

An attempt was made to generate gasoline-range aromatics from pyrolysis oil derived from rubberwood. Catalytic cracking of the pyrolysis oil was conducted using an HZSM-5 catalyst in a dual reactor. The effects of reaction temperature, catalyst weight, and nitrogen flow rate were investigated to determine the yield of organic liquid product (OLP) and the percentage of gasoline aromatics in the OLP. The results showed that the maximum OLP yield was about 13.6 wt%, which was achieved at 511 C, a catalyst weight of 3.2 g, and an N2 flow rate of 3 mL/min. The maximum percentage of gasoline aromatics was about 27 wt%, which was obtained at 595 C, a catalyst weight of 5 g, and an N2 flow rate of 3 mL/min. Although the yield of gasoline aromatics was low, the expected components were detected in the OLP, including benzene, toluene, ethyl benzene, and xylenes (BTEX). These findings demonstrated that green gasoline aromatics can be produced from rubberwood pyrolysis oil via zeolite cracking.

As such, it attracted significant attention as a renewable source of energy after the global oil crisis of the 1970s (Demirbas 2007;Lucia 2008;Demirbas et al. 2009). In addition, biomass currently is considered to be the only sustainable source that can be used to produce energy-related products, including electricity, heat, and valuable chemicals such as resins, flavorings, and other materials (Huber et al. 2006;Dodds and Gross 2007).The first generation of biofuels were primarily bioethanol and biodiesel made from sugar, starch, and vegetable oil. To date, such biofuels have been widely produced across several countries and continents, notably Brazil, South America, Europe, and the United States (Charles et al. 2007;Mojoviä et al. 2009); however, they have been produced from food-grade biomass, which could lead to critical concerns related to food security (Gronowska et al. 2009). Therefore, it is very important to be able to produce biofuels from non-food resources such as ligno-cellulosic materials: wood chips, switch grasses and most importantly agricultural wastes, such as sugarcane bagasse, corn stover and rice straw.Pyrolysis oils derived from wood-based biomass are one of the most promising renewable fuels. They are environmentally-friendly candidates because they contain a low content of sulfur compared to fossil-derived oils (Czernik and Bridgwater 2004). Recently, extensive attention has been focused on the technology of fast pyrolysis rather than slow pyrolysis, as the former produces high yield of pyrolysis oil with low water content in a PEER-REVIEWED ARTICLE bioresources.com Saad et al.

“…To improve the quality of bio-oils derived from biomass pyrolysis, Gong et al [16] and Hussain et al [17] respectively proposed the use of zeolite and cement as catalysts. Zeolite catalysts, such as ZSM-5, HZSM-5 and FCC, influences the stability of the chemical compositions of bio-oils and the characteristics of fuels during biomass pyrolysis [18][19][20].…”
