Mesoporous organosilica sorbents are effective to remove contaminants (such as glycerol or detergent) from biodiesel. Contacting biodiesel with various a mesoporous organosilica sorbents comprising phenyl and sulfonate moieties resulted in the contaminants being absorbed by the sorbent and thus removed from the biodiesel.

The present disclosure provides a process for preparing a hydrocarbon fuel from waste rubber. The process involves admixing, in a reaction vessel, at least one fluid medium with the waste rubber to obtain a slurry; wherein the concentration of the waste rubber in the slurry ranges from 45% to 70%. A reactor is charged with the slurry and a predetermined amount of at least one catalyst composition to obtain a mixture, followed by introduction of hydrogen to the reactor to attain a predetermined pressure and heating the mixture at a predetermined temperature, to attain an autogenously generated pressure, and for a predetermined time period to obtain a reaction mass comprising the hydrocarbon fuel. This reaction mass comprising the hydrocarbon fuel is then cooled to obtain a cooled reaction mass. The hydrocarbon fuel is then separated from the cooled reaction mass.

A pyrolysis oil composition that is soluble in hydrocarbon fuel, and related systems and methods for making the composition, are described. In an exemplary embodiment, a process for making a pyrolysis oil composition involves pyrolyzing biomass to generate biomass-derived pyrolysis vapor therefrom, vaporizing petroleum feedstock to generate petroleum feedstock-derived vapor therefrom, blending the biomass-derived pyrolysis vapor and petroleum feedstock-derived vapor together, condensing the blended biomass-derived pyrolysis vapor and petroleum feedstock-derived vapor simultaneously to form a condensate, and collecting the condensate.

The disclosure encompassed herein relates, in part, to a method for increasing energy density of plant biomass that can be used for production of renewable fuel, such as biodiesel oil and/or ethanol. In an aspect, genetic engineering for enhanced sugar accumulation can be achieved by overexpressing a bacterial enzyme sucrose isomerase. Sugars or oils extracted from the plants of the disclosure encompassed herein may be used for industrial purposes such as heating, producing bio-fuels such as biodiesel fuel, or lubricating applications.

This invention involves a process for reducing friction in ethanol during its transport through pipelines. This process involves combining ethanol with a polymer-based composition, characterized in that the polymer is obtained from at least 50 mol % of at least one monomer selected from the group comprising N-substituted acrylamides, N-substituted methacrylamides, N,N-substituted acrylamides, N,N-substituted methacrylamides, substituted acrylates and substituted methacrylates.

A method for determining whether a liquid hydrocarbon fuel, contained in a reservoir, comprises no more than a specified maximum permissible amount of fatty acid methyl ester (FAME) for the fuel to be accepted as being suitable for use in a specified engine.

There is described a process and an apparatus for purifying a mixture and related products. In particular, there is described a process and an apparatus for purifying a mixture comprising fats, oils and greases as are typically found in sewer waste. The process involves heating, acidifying and separating the mixture. The apparatus used includes a heating and separation device for separating into a solid fraction, an organic liquid fraction and an aqueous liquid fraction. Apparatus such as a three phase separation unit and a rotary vacuum filter may also be used.

A process for production of biofuels from algae can include cultivating an oil-producing algae by promoting sequential photoautotrophic and heterotrophic growth. The method can further include producing oil by heterotrophic growth of algae wherein the heterotrophic algae growth is achieved by introducing a sugar feed to the oil-producing algae. An algal oil can be extracted from the oil-producing algae, and can be converted to form biodiesel.
