TL;DR: In this article, the effect of extraction with hexane on supercritical water gasification has been elucidated so far, and the results were compared with the original sample and sample after extraction of microalgae Chlorella vulgaris were gasified in super critical water at 600 °C and 25 MPa.
Abstract: Algae after extraction with hexane are a promising feedstock for fuel production (such as hydrogen gas) using supercritical water gasification. However, the effect of extraction with hexane on supercritical water gasification has not been elucidated so far. In this study, original sample and sample after extraction with hexane of microalgae Chlorella vulgaris were gasified in supercritical water at 600 °C and 25 MPa and the results were compared. Algae after extraction with hexane resulted in a lower methane content and lower carbon gas yields. Rate constants for reactions in the algae decomposition reaction network were determined by fitting calculation to experimental data.

TL;DR: In this article, Raney platinum proved to be an active catalyst for the conversion of the hydrocarbons, and the potential/current density curves were measured in a galvanostatic half-cell arrangement.
Abstract: For the hydrocarbons methane through heptane, ethylene, and carbon monoxide anodic potential/current density curves were measured in a galvanostatic half‐cell arrangement. Raney platinum proved to be an active catalyst for the conversion of the hydrocarbons. In at 100°C a stationary current density of 200 ma/cm2 was measured for ethane, propane, butane, ethylene, and carbon monoxide, and 100 ma/cm2 for methane and pentane. By coulometric analyses the conversion of methane, ethane, and propane to was found to be 100%. Complete conversion of butane, pentane, hexane, and heptane apparently requires conditions different from those employed here. In potential oscillations with time were observed, which were caused by partial poisoning of the electrode on reduction of to and the subsequent self‐regeneration of the electrode.

TL;DR: In this article, the solubilization equilibria for hexane and a series of polycyclic aromatic compounds (dyes) in aqueous cationic micelles of dodecyltrimethylammonium bromide (DTAB) and TTAB were studied experimentally.
Abstract: Solubilization equilibria for hexane and a series of polycyclic aromatic compounds (dyes) in aqueous cationic micelles of dodecyltrimethylammonium bromide (DTAB) and tetradecyltrimethylammonium bromide (TTAB) were studied experimentally. Solubilizates were compared first individually, for effects of molecular shape and structure, and then as mixtures, in a search for interactive effects. Hexane solutions of solid dyes, in binary mixtures of relative mole fraction 0 to 1 for each dye, were partitioned into the aqueous micellar phase, which was analyzed by ultraviolet-visible spectrophotometry for the dyes and gas chromatography for hexane. Solubilization ratios (SRs), expressed as the ratio of solubilizate to surfactant molecules in a micelle, were obtained from the experimental data. In our experiments, the micelles contained more solubilized hexane than dye. For cases of three-component solubilization (two dyes and hexane), compounds of similar molecular shape and chemical structure performed alike as solubilizates, possibly occupying sites in the micelle interchangeably. However, when a large molecule with three or four fused rings and a smaller two-ring molecule were contained in the micelle, solubilization of the smaller molecule was always enhanced.

TL;DR: In this article, a fluoropolymer-based composite membrane was used to recover hexane from the crude mixture of soybean oil and hexane via the OSN process, showing high oil rejection and excellent long-term operational stability.
