Polymerization and cracking during the hydrotreatment of bio-oil and heavy fractions obtained by fractional condensation using ru/c and nimo/al2o3 catalystTwo-step hydrotreatment experiments were performed using three completely different bio-oil fractions namely: whole bio-oil, heavy bio-oil obtained after fractional condensation of pyrolysis vapours and pyrolytic lignin obtained by cold water precipitation of the bio-oil....
Electrothermal atomization of a substance with fractional condensation of the element being determined on a probeThis paper describes a method of electrothermal atomization with a fractional condensation of the elements being determined on a refractory probe with the aim of decreasing the matrix influences on the atomic-absorption signal....
Separation of silver from chloride and sulfate matrices by fractional condensation in a twostep graphite atomizer... It is shown that the preliminary fractional condensation of the element to be determined in the tubeatomizer can be used to decrease the interferences from the matrix....
Fractional condensation of bio-oil vaporsThe research project described in this thesis deals with an investigation on the fractional condensation of bio-oil vapors to improve the separation of some of the key components of the bio-oil and, consequently, improve the properties and the value of each...
