“…The governing idea has been to produce pyrolytically hydrocarbon-rich mixtures resembling petroleum. In our earlier investigations, the thermochemical behaviour of common fatty acid (C 18 , C 18:1 , and C 18:2 ) sodium salts [11], vegetable oil (palm, olive, rapeseed and castor oils) soaps [12], and CTO soap [13] was clarified under pyrolytic conditions.…”

Neutralised mixtures of tall oil-derived fatty acids and resin acids were separately pyrolysed (at 750• C for 20 s) by pyrolysis gas chromatography with mass-selective and flame ionisation detection (Py-GC/MSD/FID) to clarify their thermochemical behaviour. The pyrolysate of fatty acid salts characteristically contained high amounts of unsaturated aliphatic hydrocarbons and minor amounts of monoaromatics, whereas the pyrolysis of resin acid salts mainly resulted in the formation of aromatics with up to three benzene rings and only in very low amounts of aliphatic hydrocarbons. The data obtained are useful when considering the suitability of various tall oil products containing fatty and resin acid fractions for the production of biofuels and chemicals via pyrolysis.

“…In developing countries, the use of OC is of high interest, since these countries have economies largely based on agriculture and forestry. The use of these materials will depend on the state of the art of safe and economic technologies able to transform them into manageable products [7] [8]. In this way, thermochemical biomass conversion processes such as pyrolysis, gasification and liquefaction are the most appropriate [9].…”

“…Pyrolysis offers efficient utilization of OC, which is of particular importance for agricultural countries with vastly available biomass by-products [11]. The pyrolysis process conditions can be optimized to maximize the production of liquids (tar, bio-oil), solids (char) or gases whose distribution depends on the experimental conditions applied especially temperature and heating rate [7]. In particular, the production of pyrolysis liquids has been investigated with the aim of using the liquid product directly in fuel applications or by upgrading, producing refined fuels and/or chemical products [12]- [17].…”

Numerous studies regarding liquid fuel production from various sources of biomass have demonstrated that an oil product can be obtained from OC in significant yields [2]- [4] [7]. Their direct use as conventional fuels may present some difficulties due to their high viscosity, poor heating value, corrosiveness and instability.…”

In this study olive biomass was pyrolysis in a 400 cm 3 stainless steel reactor. It was externally heated by an electrical furnace in which the temperature is measured by a thermocouple inserted into the bed. The effect of the catalyst ratio to the biomass (5%, 10%, 15%, 20%, 30% and 40%) on the pyrolysis yield was investigated and compared with the uncatalyzed pyrolysis yield product. The bio-oil products yield from the pyrolysis process was found to increase as the catalyst ratio increased. The bio-oil yield from the olive oil-cake, which was 36.1% without the catalyst, reached the maximum value of 39.3% on using activated catalyst at 10% by weight. The gas products yield was found to increase upon using catalyst compared to the non-catalytic pyrolysis. The reduction in the bio-oil yield product was accompanied with a significant reduction in the oxygen content. The pyrolysis oil was examined using chromatographic analysis techniques. The chemical characterization showed that the bio-oil obtained from olive oil cake might be potentially valuable as a fuel and chemical feedstock.

Conversion of waste‐soap and soap‐like materials into diesel and gasoline by catalytic pyrolysis using virgin soap as model

et al. 2015

In this work, soap was converted into a hydrocarbon‐rich product through catalytic pyrolysis using cement as a catalyst. The intention was to develop a new economical and effective method for preparing diesel and gasoline from soap waste in food processing. The optimum conditions for pyrolysis were investigated in a batch process under static conditions at different reactor temperatures, catalyst amounts, and reaction durations. The resulting oil product was analyzed using GC‐FID, GC‐MS, and FTIR. The best yield occurred at a reaction temperature of 400 °C for 60 min with 0.3 g/g (30 mass%) catalyst in soap waste, which resulted in 0.71 g/g (71 mass%) hydrocarbons with small fractions of pyran, ketone, and oxygenated compounds of mixed functional groups. The resulting liquid pyrolysate mainly consisted of diesel‐like oil with a small fraction of gasoline and some oils that had boiling‐point temperature ranges similar to kerosene.
