A filter media for the removal of undesirable solid components from a fuel feedstock contains biomass and a catalyst used from the thermocatalytic conversion of biomass into bio-oil.

Method of removing undesirable solid components from a renewable or non-renewable feed and apparatus used in same

A green process and system are disclosed for utilizing a biomass filter aid in the filtration of a bio-oil. The process comprises filtering a bio-oil containing residual solids from a conversion reaction in the presence of the biomass filter aid to produce a filtered bio-oil. The biomass filter aid facilitates efficient removal of residual solids from the bio-oil. The spent biomass filter aid containing the residual solids may be recycled as a conversion feedstock or used as a combustion heat source in the biomass conversion system.

Solids removal from bio-oil using biomass filter aid

A process for preparing a renewable biofuel consists of subjecting a bio-oil mixture to deoxygenation in a hydrotreater and then separating hydrocarbon fractions from the deoxygenated product to form the biofuel. The bio-oil mixture contains a bio-oil feedstream and a treated bio-oil feed. The treated bio-oil feed is a stream from which undesirable heavy materials and solid materials have been removed.

Process for producing renewable biofuel from a pyrolyzed biomass containing bio-oil stream

Brominated styrenic polymer is recovered from solution in a vaporizable solvent by converting the solution in a devolatilization extruder into a brominated styrenic polymer melt or flow and a separate vapor phase comprised predominately of vaporizable solvent, recovering the melt or flow from the devolatilization extruder, and allowing or causing the melt or flow to solidify. The solidified brominated styrenic polymer can be subdivided into a powder or pelletized form. Pellets so made have improved hardness and/or crush strength properties along with reduced formation of fines. Brominated anionic styrenic polymer is preferably used in the process.

Process technology for recovering brominated styrenic polymers from reaction mixtures in which they are formed and/or converting such mixtures into pellets or into granules or pastilles

A process and system for removing bound water from bio-oil by azeotropic distillation. The process includes combining a bound-water-containing bio-oil with an azeotrope agent and subjecting the resulting treated bio-oil to azeotropic distillation under reduced pressure. The azeotropic distillation removes a substantial portion of the bound water from the bio-oil, thus producing a water-depleted bio-oil that is less corrosive, more stable, and more readily miscible with hydrocarbons.

Removal of bound water from bio-oil

A process and system for separating water from bio-oil by using a partial condenser. The process comprises partially condensing vapor conversion products from a biomass conversion reaction to produce a water-rich overhead stream and a water-depleted stream comprising condensed bio-oil. The partial condenser removes a substantial portion of the water from the bio-oil, while providing an effective and flexible process for producing bio-oil.

Removal of water from bio-oil

Concurrently fed into a reaction zone held at about 10&#xb0; C. or less are brominating agent, aluminum halide catalyst, and a solution of anionic styrenic polymer having a GPC Mn about 2000-30,000. The components are in at least two separate feed streams. The feeds are proportioned to maintain (a) the amount of aluminum halide being fed at about 0.8 mole percent or less based on the amount of aromatic monomeric units in the polymer being fed, and (b) amounts of brominating agent and unbrominated polymer in the reaction zone that produce a final washed and dried polymer product containing about 60-71 wt % bromine. The catalyst is deactivated, bromide ions and catalyst residues are washed away from the reaction mixture, and the brominated anionic styrenic polymer is recovered and dried. The dried polymer has a volatile bromobenzene content of about 600 ppm (wt/wt) or less as well as other beneficial properties.

Brominated anionic styrenic polymers and their preparation

Bromination of styrenic polymer is carried out in a closed reaction system to retain HX coproduct (where HX is HBr or HCl, or both) in the bromination reaction mixture at superatmospheric pressure. Preferably, the reaction mixture which includes the brominated styrenic polymer and substantially all of the HX coproduct formed is discharged into an aqueous quenching medium. By operating in this manner, the reaction is terminated and the brominated styrenic polymer of desired bromine content and substantially all HX coproduct are captured in the same operation, process equipment costs are reduced, and processing of the reaction mixture is facilitated.

Preparation of brominated styrenic polymers or resins

Propargyl bromide is effectively stabilized against shock or thermal decomposition by use therewith of an environmentally acceptable inert liquid solvent that forms an azeotrope with propargyl bromide.
