VANADIUM CORROSION INHIBITORS IN GAS TURBINE APPLICATIONS
The present embodiments describe a method to reduce vanadium corrosion in a gas turbine by adding an oleophilic corrosion inhibitor into a combustion fuel, in which the oleophilic corrosion inhibitor comprises carbon black support particles and magnesium bonded to the carbon black support particles. The carbon black support particles comprise a particle size less than 40 nanometer (nm), and oxygen content less than 1 weight percent (wt %), and a surface area of at least 50 square meters per gram (m.sup.2/gram).
AVIATION FUEL ADDITIVE SCAVENGER
Aviation fuel formulations receive many benefits when a manganese-containing additive is incorporated in that composition. However, to the extent that the use of a manganese-containing compound may result in the formation of engine deposits during combustion, it is beneficial to further provide a scavenger compound to the fuel composition. This scavenger compound may include a phosphorus-containing compound, an organobromide compounds, and/or a tricarbonyl compound.
PROCESS FOR CATALYTIC PRODUCTION OF PROPANOL
The present disclosure is related to a multistep process for producing renewable gasoline components from a glyceride containing feedstock. The glycerides are split to provide a stream containing fatty acids, or esters of fatty acids, and another stream containing glycerol and water. Glycerol, preferably as crude glycerol recovered from splitting, is next converted to propanols at vapor phase, providing a renewable propanol gasoline component. Another renewable gasoline component is obtained from hydroprocessing of the fatty acids or esters thereof, as a renewable paraffinic naphtha component. Blending the renewable components can provide a novel 100% renewable gasoline.
Reactor for drying and torrefying a biomass, preferably a lignocellulose biomass
A reactor for drying and torrefaction, configured for torrefying biomass, including a chamber in which two separate areas are delimited, a mechanism for mixing and transferring biomass from one end of the chamber to the other, a drying device in an upstream area of the chamber configured to dry the biomass introduced into the reactor, a torrefaction device in a downstream area of the chamber configured to torrefy biomass dried in the upstream area, and a transfer and sealing system configured to allow dried biomass to be transferred from the upstream area to the downstream area at time intervals, and to make the two areas mutually sealed during each interval. Such a reactor may, for example, find application to torrefaction of lignocellulosic biomass.
High density turbine and diesel fuels from tricyclic sesquiterpenes
A method for converting cedarwood oil into high density fuels including, hydrogenating cedarwood oil in the presence of at least one hydrogenation catalyst to generate hydrogenated cedarwood oil, removing the hydrogenation catalyst from the hydrogenated cedarwood oil, purifying the hydrogenated cedarwood oil to produce a first high density fuel, isomerizing the first high density fuel in the presence of at least one acid catalyst catalyst to generate a hydrocarbon mixture including adamantanes, and distilling the adamantane mixture to produce a second alkyl-adamantane high density fuel.
Process and apparatus for purifying a fatty mixture and related products including fuels
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.
High density diamondoid fuels from renewable oils, triglycerides, and fatty acids
A method for making high density fuels including, heating a renewable plant oil, triglyceride, or fatty acid with at least one first acid catalyst to generate a first mixture of alkyladamantanes, increasing reaction time or adding at least one second catalysts to a first mixture of alkyladamantanes to produce a second alkyladamantane mixture, separating methyl, ethyl, propyl, and/or butyl adamantanes from a second alkyladamantane mixture to produce a third adamantane mixture to produce fuels.
FUEL COMPOSITIONS FROM LIGHT TIGHT OILS AND HIGH SULFUR FUEL OILS
Methods are provided to prepare a low sulfur fuel from hydrocarbon sources, such as light tight oil and high sulfur fuel oil, often less desired by conventional refiners, who split crude into a wide range of differing products and may prefer presence of wide ranges (C3 or C5 to C20 or higher) of hydrocarbons. These fuels can be produced by separating feeds into untreated and treated streams, and then recombining them. Such fuels can also be formulated by combinations of light, middle and heavy range constituents in a selected manner as claimed. Not only low in sulfur, the fuels of this invention are also low in nitrogen and essentially metals free. Fuel use applications include on-board large marine transport vessels but also on-shore for large land based combustion gas turbines, boilers, fired heaters and transport vehicles and trains.

Diesel and jet fuels based on the oligomerization of butene
A renewable biofuel based on a highly efficient batch catalysis methodology for conversion of 1-butene to a new class of potential jet fuel blends. By tuning the catalyst and then using the dimer produced, the carbon use is about 95% or greater. This latter point will be particularly important in the future, where the source of raw materials (i.e., biomass/biofeedstock) is limited.
