Renewable Diesel from Palm Oil Using Bio‐Syngas from Palm Empty Fruit Bunches as a Hydrogen Source

Biofuels have emerged as alternatives to fossil fuels for reducing CO 2 emissions. Bio-syngas obtained from palm empty fruit bunches was used in the hydrotreating of palm oil, yielding an oil conversion and a renewable diesel purity very similar to the values obtained when using pure H 2 , under similar reaction conditions. The presence of CO in bio-syngas decreases the stability of the catalyst by coke deposition. However, this drawback can be circumvented by regenerating the catalyst or by converting CO into CO 2 and H 2 through the water-gas shift (WGS) reaction. The use of bio-syngas and its WGS product eliminates the need of an expensive H 2 purification process, and the lower H 2 purity in syngas is compensated by a moderate increase in the reaction time.

“…Palm oil is one of the most abundant and stable vegetable oils in the world. It has been widely studied in the field of biodiesel [19][20][21] and also in the field of insulating liquids. Moreover, palm oil insulating oil has been experimentally proven to have the potential to replace mineral oil as transformer insulating oil [22][23][24][25][26].…”

In order to explore the pyrolysis mechanism of palm oil as the natural ester insulating liquid from the molecular aspect, the ReaxFF reactive force field was used to simulate the pyrolysis process of palm oil. Firstly, the molecular models of the four main molecules of palm oil—tripalmitin, trilinolein, triolein, and tristearin—are constructed via density functional theory (DFT). Secondly, the vibrational frequencies of the four molecules are calculated, so as to calculate the infrared (IR) spectra. Thirdly, molecular dynamics (MD) simulations employing the ReaxFF method are performed to simulate the pyrolysis reaction of the palm oil system under different temperatures, so as to observe the generation pathways of major products used in the dissolved gas analysis (DGA) in the transformer thermal fault analysis. Finally, hydrogen bonds in the pyrolysis process are counted. It is found that the number of hydrogen bonds gradually increased with the increase of pyrolysis time and pyrolysis temperature. It reveals why the life of the insulating paper immersed with natural esters is prolonged, and why the breakdown voltage is reduced slowly in the actual experiment from another perspective. This study can provide theoretical guidance and effective reference for the thermal fault analysis of an insulating liquid using palm oil as raw material.

“…More specifically, E-fuel can be defined as all fuels produced by using renewable electricity from renewable sources (hydro, wind, or solar) with low carbon emissions, making them renewable fuels of non-biological origin used as feedstock or as an energy carrier with the purpose of mainstreaming renewable energy in transport vehicles [11]. On the other hand, synthetic fuels obtained either by pyrolysis or by catalytic hydrogenation of any triglyceride of biological origin are currently designated by different names, such as green diesel [12][13][14][15][16], renewable diesel [17][18][19][20][21][22], bio-hydrogenated diesel (BHD) [23][24][25], hydrogenated vegetable oils (HVOs) [26][27][28][29], alternative fuels [29][30][31][32][33], or advanced biofuels [34][35][36]. Furthermore, according to Figure 1, in the last decade, there has been an impressive increase in scientific publications that address the transformation of vegetable fats and oils into alkanes through different deoxygenation processes [36].…”

Nowadays, there is an intense debate in the European Union (EU) regarding the limits to achieve the European Green Deal, to make Europe the first climate-neutral continent in the world. In this context, there are also different opinions about the role that thermal engines should play. Furhermore, there is no clear proposal regarding the possibilities of the use of green hydrogen in the transport decarbonization process, even though it should be a key element. Thus, there are still no precise guidelines regarding the role of green hydrogen, with it being exclusively used as a raw material to produce E-fuels. This review aims to evaluate the possibilities of applying the different alternative technologies available to successfully complete the process already underway to achieve Climate Neutrality by about 2050, depending on the maturity of the technologies currently available, and those anticipated to be available in the coming decades.
