Production of biodiesel from natural oils and fats can be achieved using various technologies briefly discussed in this review. A particular appealing concept for production of green diesel is selective catalytic deoxygenation of renewables leading to diesel fuel products. This reaction can be performed over Pd on active carbon supports with saturated and unsaturated fatty acids and their derivatives. Key wordsbiodiesel–green diesel–deoxygenation–fatty acids

Absorption spectra of several types of diesel fuel are studied experimentally. Index of refraction of these fuels is calculated using subtractive Kramers–Krönig analysis. The ageing process of fuels is simulated by prolonged boiling. Radiative properties of diesel fuel droplets are calculated using the Mie theory and a simplified approach, based on approximations of absorption and scattering efficiency factors. It is

The global energy and environmental situations have intensified the use of alternative and clean fuels. This is true for city buses, taxis, delivery vehicles and personal cars. The unique properties of hydrogen make it suitable as a fuel for vehicles powered with both, internal combustion or electric engines, too. However, the problems associated with the production and storage of hydrogen currently limits the application of pure hydrogen as engine fuel for vehicles. As a contribution to the global strategy, this paper focuses on designing of city bus for hydrogen power using an original propulsion system. The concept of gaseous hydrogen storage under high pressure is analyzed here. In the bus on hydrogen, the cylinders with this fuel are mounted on the roof because of reasons of little available space. In the paper is proposed a method for the reconstruction of the bus, with respect to the installation of specific components for the use of compressed hydrogen gas as well as for the...

Biodiesel production from abundant bio-sources has drawn the attention of the academic as well as the industrial communities in recent years. However, one of the most serious obstacles for using biodiesel as an alternative fuel is the complicated and costly purification processes involved in its production. The difficulties involved in the separation of glycerine and other un-reacted reactants and by-products necessitate the development of new competent low cost separation processes for this purpose. In this work, a low cost quaternary ammonium salt–glycerine-based ionic liquid is proposed as a solvent for extracting glycerine from the transesterification biodiesel product. The separation technique was tested on palm oil-based produced biodiesel with KOH as a reaction catalyst. The study investigated the effect of DES:biodiesel ratio and the DES composition on the efficiency of the extraction process. The lab scale purification experiments proved the viability of the separation technique with a best DES:biodiesel molar ratio of 1:1 and a DES molar composition of 1:1 (salt:glycerine). The purified biodiesel fulfilled the EN 14214 and ASTM D 6751 standard specifications for biodiesel fuel in terms of glycerine content. A continuous separation process is suggested for industrial scale application.
