  • How to extract crude oil from spent coffee grounds?
  • Soxhlet and accelerated solvent extraction, using propanol as a solvent, and supercritical CO2 extraction methods presented statistically insignificant differences in the crude oil yield obtained from spent coffee grounds. Supercritical CO2 extraction method was selected to recover the oil.
  • Can a microwave extract oil from spent coffee grounds?
  • The production of energy and chemicals from waste biomass is an attractive alternative by comparison with first-generation biofuels and fossil feedstocks. This paper investigates oil extraction from spent coffee grounds (SCG) by means of an advanced microwave process and compares this with a conventional Soxhlet extraction (SE) method.
  • Can coffee oil be extracted from dried coffee grounds for biodiesel production?
  • In the coffee oil extraction from SCG using a Soxhlet extractor, Al-Hamamre et al. (2012) studied oil extraction from dried spent coffee grounds (DSCG) for biodiesel production; 60 g DSCG and 250 mL solvent were kept for different time spans to determine the yield.
  • Can a supercritical CO2 extractor extract oil from coffee grounds?
  • Given the great interest in utilizing CO2 as the solvent for oil extraction, this research selected supercritical CO2 extraction for oil extraction from spent coffee grounds. Additionally, our laboratory has a pilot-scale supercritical CO2 extractor with a large reactor volume (5 l).
  • Can RSM be used to extract crude oil from coffee grounds?
  • The application of the RSM to crude oil extraction from spent coffee grounds using supercritical CO2 extraction was successful. A high SV indicates a high proportion of low molecular weight and short-chain length of fatty acids. The SV obtained in this work (185.26211.15 mg KOH/g oil, shown KOH/g oil; Codex Alimentarius, 1999).
  • What solvent is used to make coffee oil from dried coffee grounds?
  • Contour plots of ratio of dried spent coffee grounds (DSCG)-to-solvent and extraction time on the coffee oil yield at 30 °C: (A) hexane; (B) anhydrous ethanol; (C) hydrous ethanol; (D) methanol.
