“…Supercritical fluid extraction (SFE) has many advantages in comparison with solvent extraction, including high reaction rate, the absence of toxic solvents, the ability to adjust solvent power to accurate extraction of target components, and production of pure crude lipids, which are not contaminated with solvents (103). The most common supercritical solvent is carbon dioxide (104, 105) but acetone, methanol, ethanol, and water also used for lipid extraction under supercritical conditions (103,106). Supercritical carbon-dioxide efficiently solubilize non-polar compounds while the extraction polar compounds can be increased using a polar co-solvent as ethanol, methanol, and acetyl chloride (107) or azeotropic mixtures as hexane/ ethanol (108).…”

Although fossil fuels remain the main source of energy, the volume of renewable sources of energy is constantly increasing. Biodiesel is a promising alternative fuel due to the number of advantages compared to fossil fuel and other types of biofuel. The specific objective of this study was to identify the difference between conventional and novel technologies applied during the whole life cycle of biodiesel production and consumption. The study offers some important insights into the recent advances in the biodiesel industry including biodiesel production from microalgal lipids, advanced homogenous and enzymatic transesterification, non-catalytic supercritical transesterification, application of microwave and ultrasound assisting technologies. Considering all the factors affecting the efficiency and safety of the biodiesel production process, here we reviewed the main principals and recent achievements in the environmental life cycle assessment of biodiesel production and consumption.

“…Supercritical CO 2 has a density and dissolving ability similar to those of liquid CO 2 , while its diffusivity, viscosity, and surface tension are comparable to those of gas [100]. As such, supercritical CO 2 offers the efficient dissolution and mass transfer of dissolved components [101]. CO 2 is a nonpolar solvent and thus it dissolves readily nonpolar molecules [102].…”

Micro- and Macroscale Consequences of Interactions between CO2 and Shale Rocks

In carbon storage activities, and in shale oil and gas extraction (SOGE) with carbon dioxide (CO2) as stimulation fluid, CO2 comes into contact with shale rock and its pore fluid. As a reactive fluid, the injected CO2 displays a large potential to modify the shale’s chemical, physical, and mechanical properties, which need to be well studied and documented. The state of the art on shale–CO2 interactions published in several review articles does not exhaust all aspects of these interactions, such as changes in the mechanical, petrophysical, or petrochemical properties of shales. This review paper presents a characterization of shale rocks and reviews their possible interaction mechanisms with different phases of CO2. The effects of these interactions on petrophysical, chemical and mechanical properties are highlighted. In addition, a novel experimental approach is presented, developed and used by our team to investigate mechanical properties by exposing shale to different saturation fluids under controlled temperatures and pressures, without modifying the test exposure conditions prior to mechanical and acoustic measurements. This paper also underlines the major knowledge gaps that need to be filled in order to improve the safety and efficiency of SOGE and CO2 storage.

“…ScCO 2 was first applied to extraction of natural products at the end of the 1980s. Nowadays, scCO 2 based extraction technology has become a mature and readily controlled process in the extraction industry, which has been utilized as a green approach for the productive extraction and recovery of valuable compounds, such as bioactive plant phytochemicals [ 13 ], nutrition and functional food ingredients [ 14 ], and other high added-value compounds [ 15 ]. However, the development of the scCO 2 technology for the production of solid particles in the pharmaceutical industry is still in the early stages.…”

Solid multicomponent systems (SMS) are gaining an increasingly important role in the pharmaceutical industry, to improve the physicochemical properties of active pharmaceutical ingredients (APIs). In recent years, various processes have been employed for SMS manufacturing. Control of the particle solid-state properties, such as size, morphology, and crystal form is required to optimize the SMS formulation. By utilizing the unique and tunable properties of supercritical fluids, supercritical anti-solvent (SAS) process holds great promise for the manipulation of the solid-state properties of APIs. The SAS techniques have been developed from batch to continuous mode. Their applications in SMS preparation are summarized in this review. Many pharmaceutical co-crystals and solid dispersions have been successfully produced via the SAS process, where the solid-state properties of APIs can be well designed by controlling the operating parameters. The underlying mechanisms on the manipulation of solid-state properties are discussed, with the help of on-line monitoring and computational techniques. With continuous researching, SAS process will give a large contribution to the scalable and continuous manufacturing of desired SMS in the near future.
