Looking for a good raw material for biodiesel at the Mexican-Yucatan peninsula, the study present data on the extraction of oil from Moringa oleifera kernals. Solvent extraction with n-hexane and ethanol, and supercritical extraction with CO2 are presented and compared … Continue reading →

Thevetia peruviana is an always green tree that grows well at adverse conditions and it is well adapted to Yucatan weather. Its kernal contains more than 60% of oil. Because the toxicity of the plat the oil is non edible and … Continue reading →

Chia (Salvia Hispanic, L.) is a crop that was used as food, medicine and paints by the Aztec Indians in Mexico before 1492, andnowhas a promissory future in several countries. Chia seeds oil is rich in polyunsaturated fatty acids, particularly … Continue reading →

The first phase of this project evaluated the reaction pathways for biomass feedstock in the presence of various cosolvents including acetone, methanol, CO2, and water using a 1 liter (di: 7.6cm, l: 23.1cm) high pressure batch reactor. Additionally, the effect … Continue reading →

 To advance the realization of algae as a feedstock for biodiesel, process technologies and closed-loop biomass use must be optimized. Life-cycle analysis (LCA) of the biodiesel production process highlights the potential significant impact of improvements in the extraction of algal … Continue reading →

To increase cotton’s consumption by inventing products and processes that demonstrate preferred use of cotton over competing fibers in needed and emerging applications involving plastics, textiles, and composites.

Biodiesel was synthesized under catalyst-free supercritical methanol reactions using a variety of oils at 250 to 325°C in a 1-liter high-pressure batch reactor. Multiple experiments were performed at 6 to 80 molar ratios of methanol to oil; product samples were … Continue reading →

Aqueous extraction using subcritical water is an environmentally friendly alternative to extracting oil and protein from oilseeds with flammable organic solvents. The effects of solids-to-liquid ratio (1:3.3–1:11.7), temperature (66–234 _C), and extraction time (13–47 min) were evaluated on the extraction … Continue reading →

The use of methyl acetate instead of methanol for supercritical synthesis of glycerol-free biodiesel from vegetable oils is a new process and its study is very limited in the literature. In this work, it has been tested for the first … Continue reading →

The ability to sensitively detect and analyze large molecules and their reaction products is important for the analysis of biological materials, including medical samples, plants and foods. Such analyses present special challenges in terms of the need to selectively extract … Continue reading →

A group of 14 different bio-sourced, renewable feedstocks have been examined for their solubility/miscibility in a variety of ‘green’ solvents, and trends in solubility have been assessed so that the data may be extrapolated to help predict solubilities of other … Continue reading →

Accurate knowledge of the phase equilibria of CO2-expanded hydroformylation reaction mixtures is essential to rational process design and development. Vapor-liquid equilibria of the following systems were measured in a variable-volume view cell at temperatures ranging from (313.15 to 353.15) K … Continue reading →

Mitragyna speciosa is a narcotic plant but with specific medicinal importance. The main components of the leaves of M. speciosa are indole alkaloids. Previous scientific researches have shown that the alkaloidal extracts possess very potent anti-inflammatory, analgesic and opioid properties. … Continue reading →

This study investigated the potential of Northern shrimp (Pandelus borealis Kreyer) by-products as a source of omega-3 polyunsaturated fatty acids (x-3 PUFAs). The by-products (heads, shell and tail) of processing accounted for approximately 50–60% of the catch. Supercritical CO2 extraction … Continue reading →
