“…They reported that the optimal co-pyrolysis temperature was 550 °C, which provides the maximum bio-oil yield and lowest proportion of polycyclic aromatic hydrocarbons. They reported that the maximum yield of aromatic hydrocarbons obtained when the optimal bamboo sawdust to waste tire ratio was 1:1 [10]. Few researchers studied the pyrolysis and gasification of tires in a pilot plant reactor at 450, 750, and 1000 °C both in nitrogen and 10% oxygen atmospheres.…”

The biodiesel has lower volatility and is costlier than the fossil diesel. Hence it is necessary to add a low cost fuel which has higher volatility, with the diesel. The tire pyrolysis oil (TPO) produced from waste tire and tubes have these desirable properties and hence in this work, we have mixed TPO with biodiesel to enhance the properties of the biodiesel. The engine tests were carried out on a single cylinder compression ignition engine with the mixture of biodiesel and TPO as fuel. From the engine tests, it is observed that the fuel mixture results in engine performance close to diesel operation at the higher injector nozzle opening pressure.

“…In Wang's study, catalytic fast co‐pyrolysis of bamboo sawdust and waste tires was conducted in a microwave‐assisted pyrolysis system for bio‐oil production with HZSM‐5 as the catalyst (Si/Al=27, particle diameter=2–5 μm). The use of HZSM‐5 catalyst significantly enhanced the proportion of aromatics at the cost of reducing the bio‐oil yield, and a maximum yield of 44.70 % was reached at the catalyst to feed ratio of 3:10 . Wang concluded that MgO was more favorable for the production of phenols, as well as being more effective for facilitating the deacidification via ketonization and aldol condensation reactions compared with HZSM‐5 in the CFP of bamboo residual (BR) run.…”

To upgrade biocrude oils from biomass pyrolysis, a novel micro‐mesoporous composite molecular sieve with HZSM‐5 structure as the core and MCM‐41 structure as the shell is synthesized and utilized. The synthesized hierarchical catalyst is characterized using X‐ray diffraction, N2 adsorption–desorption measurements, and transmission electron microscopy. Catalytic fast pyrolysis of bamboo over the composite molecular sieve is implemented using quantitative pyrolysis‐gas chromatography/mass spectrometry (Py‐GC/MS). The experimental results demonstrate that the highest relative content of hydrocarbons (34.41 %) is obtained at 600 °C when bamboo is pyrolyzed by only HZSM‐5, which has significant shape‐selective effect on the products of aromatic hydrocarbons but is easily coked. When a two‐layer catalyst bed of MCM‐41 and HZSM‐5 is used to obtaining higher catalytic activity, the two‐layer catalyst bed is capable of the promotion of hydrocarbon production with a relative content of 41.44 % because the hierarchical catalyst has higher flexibility than the two‐layer catalyst bed. It is found that the concentration of alkali solution used significantly influences the catalytic effects of composite molecular sieve. Additionally, the catalyzed transformation of oxygenated chemicals into hydrocarbons can be facilitated with the utilization of hexadecyl trim‐ethyl ammonium bromide (CTAB) in comparison with NaOH.

“…Biomass co-fired in existing combustors is usually limited to 5 -10 % of the total feedstock due to concerns about plugging existing coal feed systems [7]. The processes of pyrolysis and gasification are thermochemical conversion technologies to convert biomass feedstock into higher heating value fuel [8,9], and improve for effective production [10,11]. One improvement method to promote the production of high value fuel includes the pyrolysis technique using the zeolite catalyst.…”

“…Rice is the second world's largest cereal crop after wheat, and is a widely grown crop in Asia, but rice straw is produced as a by-product of rice production. Every kilogram of grain harvesting is accomplished by the production of rice straw to a tone of 1.0 -1.5 kg [10]. In most parts of rice fields, openfield burning of rice straw is commonly practiced in the region when there is limited time to prepare a field for the next crop.…”

In Japan, there is a large amount of biomass waste from agriculture to be used as resources. In this study, we examined the conversion of rice straw into methane gas by thermal decomposition using zeolite catalysts. Four types of zeolites, NaA, NaX, NaY and HY, with different properties, crystal structure, exchangeable cation and Si/Al ratio were used as catalysts. The mixture of rice straw and zeolite was added into the reactor, and the reactor was heated 400 o C for 1 h in nitrogen atmosphere. The amount and composition of the gas generated during the heating, and the weight of residue were examined. The results show the conversion of rice straw into methane gas can be improved using zeolites, and faujasite zeolites having Na cation, NaX and NaY, could convert rice straw into the largest amount of methane gas in this experiment. With increasing the heating temperature, production of methane gas promotes due to the promotion of decomposition reaction. The valuable gas including methane can be obtained from rice straw by heating at higher than 600 o C for 30 min with NaY addition of same weight to rice straw.
