Algae pyrolytic bio-oil contains a large quantity of Ncontaining components (NCCs), which can be processed as valuable chemicals, while the harmful gases can also be released during bio-oil upgrading. However, the characteristics of NCCs in the bio-oil, especially the composition of heavy NCCs (molecular weight ≥200 Da), have not been fully studied due to the limitation of advanced analytical methods. In this study, three kinds of algae rich in lipids, proteins, and carbohydrates were rapidly pyrolyzed (10−25 °C/s) at different temperatures (300−700 °C). The biooil was analyzed using a Fourier transform ion cyclotron resonance mass spectrometer equipped with electrospray ionization, and the characteristics and evolution of nitrogen in heavy components were first obtained. The results indicated that the molecular weight of most heavy NCCs was distributed in the 200−400 Da range. N 1−3 compounds account for over 60% in lipid and protein-rich samples, while N 0 and N 4 components are prominent in carbohydrate-rich samples. As temperature increases, most NCCs become more aromatic and contain less O due to the strong Maillard and deoxygenation reactions. Moreover, the heavier NCCs were promoted to form lighter compounds with more nitrogen atoms through decomposition (mainly denitrogenation and deoxygenation). Finally, some strategies to deal with the NCCs for highquality bio-oil production were proposed.a Calculated by difference. Carbohydrates = 100%moisture−ash− lipid−proteins.

“…An intriguing laboratory-scale experiment of ISB of a slick on water surface was conducted by Jaggi et al (2019) and assessed using FT-ICR MS, as described earlier. They reported that both unburned oil slicks and ISB result in the release of organic compounds to the water beneath a slick.…”

“…An important finding was that ISB strongly increases the concentrations of oil-related chemicals entering the water phase as a result of production of oxidized organic compounds that are soluble in water. Jaggi et al (2019) reported that this mixture was different in composition from the organic compounds entering the water from unburned oil in that the mixture from ISB contained significantly more condensed aromatic chemicals with varying amounts of the elements nitrogen, oxygen, and sulfur. This is an important finding that merits follow-up research in the laboratory and in the field.…”

The severity of oil spills depends on the quantity of material released and its physical and chemical properties. The total amount of petroleum spilled during the Deepwater Horizon incident and the relative fractions of the chemical compound classes of the Macondo oil were obtained by measurements, observations, and model calculations, with a significant amount of uncertainty. Because petroleum is an extremely complex mixture of many thousands or more of gaseous, liquid, and solid constituents, full elucidation of their compositions at the molecular level is impossible with presently available analytical techniques. This paper reviews published work on widely used analytical techniques and points out that scientists’ varying approaches to research questions and preferences for methods of analysis constitute a source of uncertainty. In addition, the focus is on two technical advancements developed over the last two decades, namely two-dimensional gas chromatography and Fourier transform ion cyclotron resonance mass spectrometry. Both were particularly valuable in the analysis of the spilled Macondo oil and its weathering products. Among the different processes of alteration of the original oil, only in situ oil burning is dealt with in this paper. This review reveals the paucity of data on this mitigation process and shows the need for more systematic coordination of methods in burned oil research studies.

Oil spills and chemical leakages have caused severe environmental problems. Physical absorption of the spilled oils and chemical reagents by absorbing materials is an efficient and economical approach to solve these problems. Herein, we have prepared a porous thermoplastic polyurethane (TPU) sponge by combining the thermally induced phase separation method with the selective dissolution of water‐soluble PEG components. The selective removal of PEG components from the walls of TPU sponges could increase the intensities of free volume holes and surface areas of TPU sponges. The content of free volume holes and surface areas of TPU sponge reached its maximum with the TPU/PEG ratio of 1:1. The increased roughness could improve the absorption capacities of TPU sponges for various oils/organic solvents. Moreover, due to its excellent compressibility, this TPU sponge could be reused 20 times with little loss of saturated absorption capacity. In addition, this TPU sponge exhibited excellent separation ability for the toluene from the toluene/water mixture and emulsion. In all, we have developed a facile method to prepare TPU sponge absorbent with excellent absorption performance, which holds great potential in the application of large‐scale oil/water separation.
