“…However, the renaissance of this oil happened in the last decade, which can be characterised by the huge amount of studies devoted to false flax. Various applications of camelina oil have been demonstrated, e.g., as a fuel for diesel transport engines (Bernardo et al, 2003) and raw material used for synthesis of biodiesel (Yang et al, 2016), hydrocarbon fuel for jets (Zhao et al, 2015) and alkyd resins (Nosal et al, 2015). Camelina sativa oil is applied for production of potential adhesives containing epoxide (Kim et al, 2015) or acrylate and hydroxyl functionalities .…”

Camelina sativa is well known due to high content of polyunsaturated fatty acids in its oil. Till now this oil has been studied mainly for applications as raw material for synthesis of resins, biodiesel and hydrocarbon fuels. This study examines the oxidative stability of cold-pressed Camelina sativa (also known as camelina, false flax or gold-of-pleasure) oil and its extracts of spices. Despite the high content of polyunsaturated fatty acids, Camelina sativa oil appeared more rigid against oxidation than rapeseed or flax oil. Extracts of different spices were prepared by maceration in camelina oil at room temperature for 24 h. The stability of extracts was determined under accelerated oxidation conditions and monitored by peroxide values. Most of the tested additives (e.g., bay leaves, allspice, clove, barley sprouts, coriander, ginger) did not influence or even decreased oxidative stability of the oil. However, oil with thyme additive demonstrated remarkably higher stability then Camelina sativa oil alone. Press-cakes of camelina seeds were extracted with two polar solvents (ethanol or water) and their mixtures under variable conditions (room temperature or reflux). Prepared polar extracts of press-cakes were characterised by total polyphenol content (Folin–Ciocalteu method) and antiradical activity against 1,1-diphenyl-2-picryl hydrazyl and galvinoxyl.

“…However, catalytic cracking is an effective and simple method to produce biofuel from vegetable oil, with advantages of low operational cost, flexibility with respect to oil sources, and compatibility with available infrastructures [10][11][12]. The catalytic cracking process of vegetable oil takes place in two stages: thermochemical decomposition of triglyceride molecules to fatty acids; degradation of fatty acids and the formation of hydrocarbons [1,13].…”

Hydrodeoxygenation (HDO) is an effective method for bio-oil upgrading. However, the high hydrogen consumption resulted in high bio-oil upgrading cost. In this study, an novel method of hydrogen generation from water for bio-oil HDO was reported. Zinc metal with zero valency was used to generate hydrogen through zinc hydrolysis reaction in the bio-oil HDO process. The effects of different temperatures (20°C, 250°C , 300°C , 350°C , 400°C ) on in situ bio-oil HDO was investigated. The results showed that high temperatures resulted in high hydrogen yield that led to promoted HDO activity over zinc metal-based materials. Although 20°C bio-oil HDO process generated the highest oil phase yield at 14.07%, 400°C bio-oil upgrading process produced upgraded bio-oil with highest hydrocarbons content at 68.95%.Physicochemical properties of raw bio-oil improved significantly after bio-oil HDO upgrading at higher temperatures (250°C, 300°C, 350°C and 400°C). The pH of upgraded bio-oils (5.70-6.49) increased significantly compared to raw bio-oil (3.24). The higher heating value of upgraded bio-oils (28.67-33.43MJ/kg) increased significantly compared to raw bio-oil (15.54 MJ/kg), and valuable hydrocarbons content improved significantly from 16.94% in raw bio-oil to 37.86 -68.95% in upgraded bio-oils.
