“…Equation is a standard formula used to relate the heating values of biomass and pyrolysis products with their elemental analysis. It is a verified and widely applied equation to determine the energy contents of any type of organic material. , The C, H, N, and S contents of the liquid products were analyzed with CHNS analyzer as described in Section 2.1. The bio-oil sample for the CHNS analysis was produced using the infrared furnace from 500 mg of sample packed in a similar manner as in the CATA experiment. When the biomass sample was heated at the specified temperature in the reactor, the bio-oil was produced.…”

Pyrolysis is a well-established method of converting biomass to different types of value-added products, such as high energy density biofuels and chemicals. In this work, chicken-litter waste and rice husk were pyrolyzed at different temperatures with the aim of investigating the thermal behavior and energy recovery potential of the feedstocks. Computer-aided thermal analysis and thermogravimetric analysis were employed to study the pyrolysis properties of each biomass in a temperature-controlled regime. The specific heats of chicken litter and rice husk samples during their pyrolysis and the energy content of their pyrolysis products were investigated to determine the energy required to complete the pyrolysis of each sample and the energy recovery potential of each pyrolytic product. Most of the volatile products were evolved at 350 to 450 °C with CO2, CO, and CH4 being the dominant gas products from both samples throughout the pyrolysis process. At 500 °C and at a heating rate of 10 °C/min, the gas, bio-oil, and biochar yields from chicken litter and rice husk were in the ranges of 18 to 19, 35 to 39, and 42 to 47 wt %, respectively, with a total recoverable energy value of 12.7 MJ/kg from chicken litter and 13.9 MJ/kg from rice husk. The energy consumed to heat the samples to the final pyrolysis temperature of 500 °C was also estimated to be 1.2 and 0.8 MJ per kilogram of chicken litter and rice husk, respectively. With the measured values, the efficiency of the pyrolysis of chicken litter and rice husk samples is estimated to be 84% and 89%, respectively, assuming the heat required to carry out the pyrolysis process is supplied by combustion of the evolved pyrolytic gas products. If the pyrolysis is instead driven by solar thermal energy, the overall efficiency will increase to 92% for the chicken litter and 94% for the rice husk pyrolysis.

“…Ignorance regarding the energetic properties of the lignocellulosic materials from agricultural environments has led to numerous investigations determining the calorific value, ash, and elemental composition of the wood of different crops, such as the orange tree [19][20][21], the olive tree [8,20,21], the almond tree [19,20,22], the apple tree [23], the vine [8,19,20], and even herbaceous plant remains from greenhouses [24,25]. The heating or calorific value is one of the most important aspects related to the use of biomass, as it expresses the energy content of the biomass fuel and is a key parameter that has been widely used for the development of calorific power prediction models based on elemental, proximal and structural composition [26][27][28][29][30], although unfortunately the accuracy of the correlations based on those analyses are generally not very high [31].…”

The importance of replacing fossil fuels with new energy routes such as the use of biomass leads to the improvement of sources such as agricultural and forest systems through adequate management techniques.The selection of the vegetal material and the management practices can influence the properties and quality of the obtained biofuel. The properties of the biomass obtained from pruning almond trees (Prunus dulcis (Mill)) have been analyzed in this study. Two varieties were tested, Marcona and Vayro, with three rootstocks, GF305, GF677 and GN Garnem, under different fertilization systems. The quality of the biofuel was evaluated with respect to the chemical composition and gross calorific value. We observed that the variables that mostly influenced the gross calorific value of the biomass were the variety, the rootstock and, primarily, the variety-rootstock interaction. Marcona presented better biomass properties than Vayro. Trees grafted on GF305 obtained a higher gross calorific value than the ones grafted on GF677 and GN Garnem. The percentage of nitrogen highly depended on the fertilization treatment applied, with saccharides and aminoacid fertilization accumulating a higher level of nitrogen than the humic and fluvic fertilization.

“…The results of the elemental analysis and determination of the ash content [12] of samples show that an increase in lignin content leads to a substantial increase in the content of the major element -carbon. At the same time, an increase in the ash content of the lignocellulose material is accompanied by the depletion of its organic composition, which must have a negative effect on the heating value.…”

Mechanochemical modification of the composition and structure of plant raw materials to control the combustion of alternative fuel

The possibilities of mechanochemistry in processing of renewable lignocellulose raw material into solid kinds of biofuel are demonstrated in this work. A review of lignocellulose raw materials promising for our country is presented. These raw materials include wastes from agriculture and forestry, and the biomass of rapidly growing plants. The physicochemical properties of lignocellulose materials with different delignification degrees were modeled with the help of the artificial mixtures of plant raw material with purified cellulose and lignin. The data illustrating the effect of disperse state and lignin content on the reactivity of the material in subsequent combustion are presented. The tests at the combustion bench with the thermal power up to 5 MW allowed determining the optimal combustion parameters for the obtained biofuel in the autothermal mode.
