摘要:
A method for producing fatty acid alkyl esters from biolipids through transesterification and/or esterification reactions uses a flow-through cavitation device for generating cavitation bubbles in a fluidic reaction medium. The fluidic medium is passed through sequential compartments in the cavitation device having varying diameters and inner surface features to create localized reductions in fluid pressure thus vaporizing volatile alcohols and creating an increased surface area and optimized conditions for the reaction to occur at the gas-liquid interface around the bubbles.

Blown corn stillage oils and methods for making blown corn stillage oils are disclosed. In one aspect the corn stillage oils are stripped to reduce the acid value of the resulting blown, stripped corn stillage oil. The method includes heating a corn stillage oil to a temperature of at least 90° C., and passing air through the heated oil to produce a blown corn stillage oil having a viscosity of at least 50 cSt at 40° C. In one aspect, the blown corn stillage oil is stripped to reduce the acid value of the blown, stripped corn stillage oil to 5 mg KOH/gram or less.

Disclosed are methods of making, and processes of using phosphorous-promoted zeolite-containing catalysts in the conversion of hydrocarbonaceous materials such as hydrocarbons and biomass. Such disclosed methods of making include: spray drying of the catalyst precursor slurry followed by phosphorous promotion of the resulting spray dried material.
摘要:
An automated system and process for the titration of either Waste vegetable oil (WVO) or virgin vegetable oil during its chemical conversion into Biodiesel. A system capable of automatically measuring and controlling the addition of a suitable amount of titration fluid is controlled in reaction to a pH level measurement tool, as determined by sensors and software. The process comprises forming a single phase solution of WVO and titrant in a ratio of between 10:1 to 50:1.

The invention relates to a process for esterifying free fatty acids in vegetable and animal fat with alcohols over heterogeneous acidic ion exchange resin catalysts at temperatures of 60 to 120° C.
摘要:
The present invention relates to a new process for extracting fatty acids from aqueous biomass in a membrane contactor module. The present invention also relates to an integrated process combining biomass concentration and/or diafiltration and fatty acid extraction in said membrane contactor module.
摘要:
The present invention describes a method of producing fatty acid alkyl esters and glycerin implementing, in a reaction section, a set of transesterification reactions between a vegetable or animal oil and an aliphatic monoalcohol, and using a heterogeneous solid catalyst, comprising: a) a stage of recontacting the effluent coming from the reaction section, and separated from the excess alcohol, with a glycerin phase, b) a stage of mixing said effluent with said glycerin phase, and c) a glycerin phase decantation stage. The supernatent ester phase obtained after decantation is then optionally sent to a coalescer, also allowing separation of the glycerin, then to a purification stage by adsorption on solids.
摘要:
A method for the cationic polymerization of unsaturated biological oils (e.g., vegetable oils and animal oils) based on the cationic reaction of double bonds initiated by superacids is provided. The process occurs under very mild reaction conditions (about 70-110° C. and atmospheric pressure) and with short reaction times. The polymerized oils have a viscosity about 10 to 200 times higher than the initial oil and relatively high unsaturation (only about 10-30% lower than that of initial oils).
