Pressurized liquid extraction of macauba pulp oil

The Canadian Journal of Chemical Engineering, 2017
AbstractThe aim of this study was to investigate the extraction of oil from macauba pulp using ethanol and isopropanol as pressurized solvents. Experiments were carried out in a semi‐continuous extractor system at various temperatures (40, 60, and 80 °C) maintaining the pressure fixed at 10 000 kPa and the solvent flow at 3 mL/min and also using ...

Spatio-temporal characterization of the fruit metabolism in contrasting accessions of Macauba (Acrocomia aculeata)

Plant Physiology and Biochemistry, 2022
Although Macauba (Acrocomia aculeata) has been highlighted by its high-quality oil to fit edible and nonedible purposes, data addressing carbon and nitrogen metabolism underlying development and ripening of fruits remain scarce. In addition, accessions of Macauba exibit varied oil yield in fruits, including during the fruit development stages. Here, we

Acrocomia Species (Macauba Palm)

1996
The tropical oil palms of the genus Acrocomia, spread all over the South and Central American continents, are very important since they produce oils that may be used for human consumption, the cosmetic industry, and also as a source of alternative fuel (Lleras 1985).

Economic feasibility of biodiesel production from Macauba in Brazil

Energy Economics, 2013
Abstract In this work the economic feasibility of biodiesel production in Brazil by using the Macauba oil as raw matter is studied. The software SIMB-E, in which a cash flow model applied to biodiesel production is implemented, was used during simulations.

Initial development of seedlings of macauba palm (Acrocomia aculeata)

Industrial Crops and Products, 2016
Abstract The macauba palm ( Acrocomia aculeata ), also know as the grugru palm, macaw palm and coyol palm, has great potential for the production of oil for biodiesel. The aim of this study was to evaluate the development of macauba palm seedlings in two types of soil, with and without the use of a soil conditioner.

Deoxygenation of Macauba acid oil over Co-based catalyst supported on activated biochar from Macauba endocarp: A potential and sustainable route for green diesel and biokerosene production

Fuel, 2020
Abstract Conventional biofuels, as biodiesel and bioethanol, are oxygenated compounds that have different physical-chemical properties when compared to fossil fuels. Otherwise, drop-in biofuels are bio-hydrocarbons that have the same chemical composition of fossil fuels.

Oil extraction from macauba pulp using compressed propane

The Journal of Supercritical Fluids, 2017
Abstract In this study, the extraction of macauba pulp oil (MPO) using compressed propane as a solvent was investigated, and compared with conventional (Soxhlet) extraction. Extractions with propane were carried out in order to investigate the effects of temperature (333–373 K) and pressure (4–12 MPa) on the oil yield and the chemical composition of ...

Macauba oil as an alternative feedstock for biodiesel: Characterization and ester conversion by the supercritical method

Journal of Supercritical Fluids, 2014
Abstract In this work different samples of Brazilian macauba oil obtained from mechanical pressing were characterized and production of esters of fatty acids using a catalyst-free continuous process under supercritical alcohols was assessed. Analysis of oil samples showed that the major fatty acid on pulp oil was oleic acid (mean value 62.8%), the ...
