Bio-Oil Production by Thermal Cracking in the Presence of Hydrogen

Abstract

This paper describes the bio-oil production process of a mixture of agricultural wastes: discarded soybean frying oil, coffee and sawdust, by pyrolysis and thermal cracking in the presence of hydrogen. The fractions obtained in the pyrolysis and/or cracking processes were divided into a light fraction and a heavy one. All the fractions were analyzed by comprehensive two-dimensional gas chromatography with time-of-flight mass spectrometry detection (GC×GC/ TOFMS). The characteristics of the fractions obtained in from the cracking process in the presence of hydrogen were similar to those of petroleum-based naphtha, while the fractions obtained by pyrolysis contained significant quantities of compounds such as furanmethanol, hexanol, and benzofuran, whose commercial value is high.

Effect of Sulfur on Wood Tar Biopitch as a Sustainable Replacement for Coal Tar Pitch Binders

“…Bio-oil was synthesized from the pyrolysis of fresh eucalyptus sawdust under an Ar atmosphere using an in-house pyrolysis system following a method previously reported , and is schematically shown in Figure . 1 kg of eucalyptus sawdust was introduced in a stainless-steel reactor, which was connected to two condensers placed in series.…”

Effect of temperature on bio-oil fractions of palm kernel shell thermal distillation

“…It is a renewable energy that can be changed into bio-fuel by different methods such as pyrolysis, gasification, combustion, and liquefaction. These methods are conventional and the disadvantages of these methods are higher temperature, long processing time, and usage of catalysts [2,3]. Fast pyrolysis using palm kernel shell (PKS) is one of the methods that can improve the properties of the biomass to the next level of advancement.…”
