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

2015

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.

“…Slow pyrolysis occurs at a low heating temperature of 400°C and a long solids residence time causing the secondary cracking of the primary products (Brewer, et al, 2009), (Tiilikkala, et al, 2010). The major product yields include biochar up to 45% and bio-oil (vinegar and tar) about 30% (Baimark and Niamsa, 2009), (Chalermsan and Peerapan, 2009).…”

“…Generally, the major components of wood vinegar are acetic acid and methanol while acetone, methyl acetone, acetaldehyde, allyl alcohol, furan and furfural, and formic, propionic and butyric acids among others are also present (Tiilikkala, et al, 2010). On the other hand, wood tar generally consists of aldehydes, ketones, acids, and esters compounds.…”

“…Similarly, wood vinegar and tar have been used as insects (mosquitos, butterflies and caterpillars), termites and molluscs repellant. They have been used as a biocides successfully without any notable environmental effect because of their high acetic acid contents (Kiarie-Makara, et al, 2010), (Tiilikkala, et al, 2010), (Masum, et al, 2013), (Pangnakorn, et al, 2012). Masum et al (2013) and Pangnakorn et al (2012) noted that wood vinegar essentially increases the soil microbial population when applied on the soil thus stimulating plant root growth while offering plant immunity against diseases.…”

Slow pyrolysis process has been used in the recent past to yield wood vinegar from various biomass wastes with a quest to investigate their chemical composition and possible uses. This study utilizes the abundant banana wastes in Uganda including leaves, pseudostem and peels (mpologoma, kisansa and kibuzi species) in the slow pyrolysis process to yield vinegar, tar and biochar. Characterization of these banana wastes' vinegar and tar fractions were investigated via chromatographic and physicochemical analysis. The principle compounds present in the banana wastes vinegar and tar as per percentage peak areas were acids (68.6%), alcohols (62.5%), ketones (27.6%), phenols (25.7%) and furans (21.8%). The products characterization indicate that vinegar and tar contain compounds that can be used as pesticides, termiticide, fungicides, insect repellants, anti-leaching and soil degradation agents. Thus wood vinegar and tar can have sustainable impacts on agricultural sectors and chemical industries especially for developing countries.

Termiticidal activity of wood vinegar from Toona sinensis (TS) sawdust has been evaluated against Coptotermes curvignathus. TS wood vinegar was produced at 250-300°C pyrolysis temperature, and a no-choice test was applied for evaluating termiticidal activity with thirty-three active termites. The concentrations of TS wood vinegar in the dried filter paper was prepared to 0% (solvent only), 2%, 4%, 6%, and 8%. The TS wood vinegar showed strong termiticidal activity and that concentrations of wood vinegar significantly influenced mortality of termite. The termite mortality increased when the concentration of wood vinegar increased, at a concentration of 8% all termites dead after 3 days tested. Forty constituents were characteristic on the basis of GC-MS data, and 33 components were identified. The organic compounds in TS wood vinegar were classified into carboxylic acids, phenols, ketones, amides, aldehydes, furans, esters, alcohols, sugar derivative, and ether, and among of this components, acetic acid comprised 57.43%. The contents of organic fraction of TS wood vinegar and largely acetic acid might be responsible for the termiticidal activity. Base on physicochemical properties, TS wood vinegar has a good quality as well.
