“…This takes place when the cellulose structure has absorbed enough energy to activate the cleavage of the glycosidic linkage to produce glucose and oligosaccharides. Aguiar et al [33] have reported that hemicellulose decomposes between 200 and 260 °C, most of the decomposition happens to 180 °C. Decomposition of cellulose is complete at around 360 °C.…”

Abstract:In this study, gamma irradiation induced degradation of orange peels (OP) was investigated. The lignocellulosic biomass degradation was carried out at doses of 0 (control), 600, 1800 and 3500 kGy using a Co-60 gamma radiation source. The samples were tested for total and reducing sugars. The concentrations of total sugars ranged from 0.530 g•g but not significantly, which suggests that lignocellulose and sugars profiles were partially degraded after gamma irradiation.

“…Waste orange peels can be used as valuable feed additives for animals; however, during transport orange peels cause considerable corrosion damage to the trailers transporting them. The solution to this problem may be to use orange skins to obtain orange oil, in which the main component is an organic compound with numerous applications-limonene [1]. Orange oil is possible to obtain from orange peels with the help of hydrodistillation, steam distillation, or microwaves.…”

Abstract:The isomerization of limonene over the Ti-SBA-15 catalyst, which was prepared by the hydrothermal method, was studied. The main products of limonene isomerization were terpinolene, α-terpinene, γ-terpinene, and p-cymene-products with numerous applications. The amount of these products depended on reaction time, temperature, and catalyst content. These parameters changed in the following range: reaction time 30-1380 min, temperature 140-160 • C, and catalyst content 5-15 wt %. Finally, the most favorable conditions for the limonene isomerization process were established: a reaction time of 180 min, temperature of 160 • C, and amount of the catalyst 15 wt %. In order to obtain p-cymene (dehydroaromatization product), the most favorable conditions are similar but the reaction time should be 1380 min. The application of such conditions allowed us to obtain the highest amounts of the desired products in the shortest time.

“…The pyrolysis of mandarin peel has the potential as an eco-friendly treatment technique and sustainable energy source, especially in mandarin production areas, such as Jeju-Do, and some recently published papers can be found on the subject. To our knowledge, Aquiar et al [8] studied the pyrolysis of orange peel residues in a fixed bed reactor and Miranda et al [9] studied the pyrolysis of sweet orange dry peel using a thermogravimetric analyzer and bench-scale pyrolysis experiments. However, an analysis of the kinetic data and detailed research on the pyrolysis byproducts at different reaction temperatures remain to be reported.…”

“…In addition, the chemical composition of orange peel is quite different from that of mandarin peel [10]. The thermal degradability is affected by the chemical composition, as the different components of the lignocellulosic material have different thermal behaviors [8,11]. Therefore, a fundamental investigation on the kinetic analysis and product characteristics for the pyrolysis of mandarin peel needs to be performed prior to its application in Jeju-Do.…”

The thermal property of the pyrolysis reaction of mandarin peel was studied using thermogravimetric analysis (TGA). Thermogravimetric analyses with temperature increases of 10, 20 and 40 o C/min showed large weight losses within the temperature range 150-590 o C. Differential thermogravimetric (DTG) analysis curves illustrated that the pyrolysis of mandarin peel was a multi-step process, consisting of water desorption, the decomposition of pectin, hemicellulose, cellulose and lignin, and devolatilization of the residual char. The apparent activation energies ranged between 119 and 406 kJ/mol, depending on the pyrolytic conversion. The pyrolysis products were analyzed, using pyrolyzergas chromatography/mass spectrometry (Py-GC/MS), to evaluate mandarin peel as a renewable source of valuable industrial chemicals. The pyrolysis products of mandarin peel contained high portions of methanol and acetic acid, as well as valuable compounds, such as limonene and vitamin E.
