Background Heavy and super-heavy oils are characterized by a high content of resins and asphaltenes, which complicate the transportation and refining of oil and lead to an increase in the cost of refinery products. Currently, of particular interest…
Biochar has been widely applied for the remediation of petroleum-contaminated soil. However, the effect of biochar on the transport of petroleum degradation bacteria has not been studied. A typical Gram-positive petroleum degradation…
Fast pyrolysis is a controlled process of biomass thermal decomposition designed to yield high volumes of liquid bio-oil, which can subsequently be upgraded into high energy density transportation biofuels such as green gasoline, green jet fuel and…
The heterogeneous structure of biomass causes the complex compositions of bio-oil, thereby posing huge challenges for the extraction of value-added chemicals from bio-oil and the catalytic upgrading of bio-oil in existing petroleum-refining…
Abstract: The process of deasphalted oil thermal cracking in the presence of catalysts formed from oil-soluble Fe, Mo, Ni, and Co acetylacetonates is studied. It is shown that the used catalysts substantially change physicochemical properties of the…
The characterization of the feedstock is an important analytical task in the modeling and development of processes for upgrading of petroleum residues. This work presents the results of fractionation of the vacuum petroleum residue by extraction…
Co-processing renewable feedstock in existing refineries could be a prompt and ready-to-use approach to decarbonize the transportation sector, without large modifications to current processing infrastructures. In this study, we explore the…
Abstract: The modern concepts of crude oils and refinery products as petroleum disperse systems are surveyed, as well as the related possibilities of optimizing crude oil refining processes. Through the optimal blending of components, it is possible…
Background Heavy and super-heavy oils are characterized by a high content of resins and asphaltenes, which complicate the transportation and refining of oil and lead to an increase in the cost of refinery products. Currently, of particular interest…
Polymalic acid (PMA), a homopolymer of L-malic acid (MA) generated from a yeast-like fungus Aureobasidium pullulans, has unique properties and many applications in food, biomedical, and environmental fields. Acid hydrolysis of PMA, releasing the…
Currently such factors as the use of heavier feedstocks, permanent strengthening of requirements to oil and gas product quality, introduction of technical regulations for oil products, which, in turn, necessitate the development of new technologies…
Modern industry strongly relies on the molecular analysis of fossil petroleum and petroleum-derived materials. In the context of a circular economy and carbon neutrality, the chemical description of alternative feedstock materials, such as waste…
Petroleum coke and biomass/coal co-gasification is a promising approach for efficiently integrating the individual advantages of different gasification feedstocks with syngas production. Therefore, research on syngas production, reactivity…
Biochar has been widely applied for the remediation of petroleum-contaminated soil. However, the effect of biochar on the transport of petroleum degradation bacteria has not been studied. A typical Gram-positive petroleum degradation…
As discussed extensively in this book, biorefinery is perceived as a promising platform for the sustainable conversion of biomass into a variety of value-added products. As a result of attempts to replace a nonrenewable feedstock with renewable…
With the advent of alternative fuels for aviation, and constantly increasing demands, it is vitally important that feedstocks for these fuels are selected in the right way. Replacing food producing crops to fuel producing crops may not always be a…
Biodiesel, an efficient alternative for the depleting fossil fuel, has recently gained wide acceptance among the various communities due to it humane approach to the environment and health. The global community has started realizing the surreptitious…
