“…This negative situation creates the need accelerate the promotion of local resources and to diversify energy resources [5]. With the norms determined for fuel emissions and clean energy studies, biodiesel has developed and continues to develop as an alternative to diesel fuel over the years [4][5][6][7]. The most important feature that distinguishes biodiesel from other alternative fuels is that it contains oxygen in the range of 10-15% by mass in its structure.…”

Scientists continue to work in order to obtain clean and efficient energy in a sustainable and economical way. Biodiesel is an important research topic not only because it is a renewable energy source, but also because it is an environmentally friendly fuel that can be produced as efficiently as petroleum-derived fuels. The raw materials used are as important as the production parameters in the production of biodiesel fuels. Hemp is not a widely cultivated plant because its cultivation is subject to government control. However, by breeding, the production of species containing low amount of stimulant and high amount of seed and fiber can be realized. In case of an efficient fuel production in compliance with the determined standards, the hemp plant can be accepted as a raw material that can also be evaluated in the field of energy. In order to guide the studies to be carried out for this purpose, in this study, the conformity of the fuel obtained by producing biodiesel from hemp seed oil to the standards was examined. As a result of the fuel analysis, it has been seen that the fuel properties of the produced hemp biodiesel are largely compatible with the TS EN 14214 standards. The results obtained provided a sufficient starting point for the development of the study.

“…Castor biodiesel stability was noticed up to 150°C and formed intermediate compounds at high temperatures. John et al 38 generated fuel properties by adopting spectrometric methods (like GC‐MS and Fourier transform infrared spectrum [FTIR] with thermogravitometry and differential scanning calorimetry [TG‐DSC]) to assess the quality of hemp ( Cannabis sativa L.) biodiesel. DSC and TG‐DTG results matched well with GC‐MS and FTIR results.…”

Thermal characteristics of biodiesels are useful in system design, modeling, and operation. Such investigations are extensively being carried out in combustors, engine, and process industries. This article examines the thermal characteristics of jatropha (Jatropha curcas), honge (Pongamia pinnata), and their equal mixing from thermogravitometry and differential scanning calorimetry (TG‐DSC) curves for the specific 10°C/min heating rate under atmospheric air. Fuel properties are measured following ASTM standards to compare with diesel properties. Each experiment was repeated three times, and the properties showed insignificant scatter. The average properties of the repeated tests are presented. Two phases of decomposition were observed for diesel, whereas three (viz., devolatilization of aqueous fractions, combustion of methyl esters, and combustion of carbonaceous residues) in biodiesels. Jatropha oil methyl ester (JOME) is thermally stable compared to honge oil methyl ester (HOME). Mixed biodiesel (JOME+HOME) is prone to oxidation due to the high content of oleic and linoleic acids. Recorded onset and offset temperatures of mixed biodiesel are low compared to pure biodiesel. Mixed biodiesel exhibited high volatility resembling diesel characteristics. It exhibited an enthalpy of 240 J/g, whereas the enthalpy of diesel, jatropha, and honge exhibited enthalpies of 130, 321, and 570 J/g, respectively. The combustion index (S) of diesel, jatropha, honge, and mixed biodiesel was 41.6, 82.8, 77.74, and 64.6, respectively. Mixed biodiesel reduces the intensity of combustion (Hf), promising better combustion characteristics. Thus, mixed biodiesel shows the potential of an efficient alternative energy source.

In this article, we overview a very important type of natural fibre, namely, hemp fibre. We consider the exclusive structure, properties, modification, the composite or nanocomposite formation and exceptional application zones. Industrial hemp fibres have been commonly developed and possess high cellulose amounts. The long hemp fibres can be termed bast or flax fibres. Hemp fibres are eco-friendly, and have light weightiness and stiffness properties. Consequently, to enhance the use of hemp fibres at engineering level, research has focused on improving the mechanical or thermal and high-tech features of these fibres. In doing this, the surface modification or treatment of hemp fibres has been notably considered. The modified fibres have been found valuable for developing certain derived materials such as polymeric composites and nanocomposites in particular. Consequently, including hemp fibres as additives in composite or nanocomposite matrices has been explored for manufacturing high performance ecological, recyclable, biodegradable and sustainable materials. Application areas identified for the hemp and related composites or nanocomposites include the synchrotron and neutron scattering, water treatment aiming dye removal, automobiles, textiles and construction. However, there is insufficient literature on these technologically important fibres and ensuing materials. Comprehensive future efforts may better resolve the challenges regarding reproducibility and long life-cycle high-tech applications of hemp fibres.
