Within spontaneous-ignition engines, efforts are being made to obtain and implement the following alternative fuels, based principally on biomass:. It should be stressed that vegetable-based fuels will solidify more easily at low temperatures. Hence, the fuels of the future should comprise: It was found for biocomponents used in fuels that the standard requirements for petroleum generacui and for some biocomponents are maintained.

The raw material must be initially prepared by fragmentation, grinding and drying.

FAME are aggressive to rubber, to some plastics, and paint coats. It is just because of the fears for the stability of esters in long-term storage conditions that biodiesels may not be used drugij combat vehicles in the US army.

The results of present research concern the pyrolysis bio-oil, derived from microalgae biomass i. Storage and safety characteristics for methanol. However, for rapeseed oil, viscosity is 20 times as high as that for diesel oil, making difficulties in pumping and spraying the fuel; it may be necessary to heat up the fuel or air before feeding the fuel to the injection system.

Qualitative analysis GC-MS has shown that our bio-oil is a complex mixture of compounds of different structures and properties. It should be kept in mind at the same time that carbon is the basic energy-carrying element which is present biopaliea chemical compounds of biofuels. Moreover, the following biofuel groups were defined for their specific uses: What is essential, is the advantageous effect of transesterification of rapeseed oil since the average droplet size of rapeseed oil methyl esters is only twice that of diesel oil.

Thermo-chemical conversion of Chlorella pyrenoidosa to liquid biofuels. The kinematic viscosity of biodiesel and its blends with diesel fuel. Journal of Applied Phycologyvol.

The technologies for their production are based mainly on edible feed raw materials. Yeast fermentation is required for the production of ethanol.

Diesel oils and rapeseed oil esters are fuels obtained from different raw bio;aliwa, therefore, they have different chemical compositions and different physico-chemical properties. The dominant content of glucose may be extracted directly from the plants and then only mild hydrolysis conditions are required.

Methanol is xrugiej poison; it is toxic because of its decarboxylase taking place in the human body, which produces methanal formaldehyde. Research studies are in progress on the use of tailored antioxidant packages in biofuel formulations.

We are IntechOpen, the world’s leading publisher of Open Access books. Methanol is frequently used in vehicles which are powered by fuel cells. Without changing their viewpoints on gsneracji need to restrict the use of the component, engine and car manufacturers established the quality requirements for ethanol in their guidelines issued in March As regards the rate of evaporation, it is low for methanol which leads to another very important advantage: It is assumed that, in generavji foreseeable future of the production and use of biofuels alternative fuelsthat such fuels should:.

Biofuels in Storage and Operating Conditions

Moreover, the cost of energy which should be added is not insignificant. A portion of syngas is formed by oxidation of biomass and another portion — by steam reforming pyrolysis. That situation results from relatively large and heavy molecules of triglycerides, as compared with diesel oil hydrocarbon molecules. Additional protective means will be necessary in the logistics of such fuels elimination of moisture, completely enclosed vessels, equipment and transfer processes, etc.

Ash content Incineration residue. A few methods have been developed for the production of bioethanol which can clearly reduce production costs: The relationship is shown in Figure 3.

The raw material is to be converted into syngas which can be then processed into methanol. The permissible duration of storage for pure esters is the subject of dedicated tests being carried out to determine the parameter.

Thus, taking into biopaliwq the provisions of said Directive and our own experience, gained from our research program, the following definition of biofuels is proposed:
