A two-stage reactor/process is disclosed for the conversion of solid particulate biomass material and includes: a first stage, in which solid particulate biomass material is pyrolyzed to primary reaction products, and a second stage in which the primary reaction products are catalytically converted in a second stage which is operated at a temperature higher than that of the first stage.

Two-stage process for conversion of solid biomass material

Biomass is converted into a bio-oil containing stream in a riser reactor containing a cooling media. The cooling media quenches the rapid heat transfer to the biomass during cracking of the biomass in the mixing zone of the riser. By lowering the temperature to which the mixing zone effluent is exposed, production of carbon monoxide and light gases is decreased during thermolysis of the biomass.

Use of cooling media in biomass conversion process

Catalyst compositions comprising a phosphorous-promoted ZSM-5 component and a silica-containing binder, and methods for making and using same, are disclosed. More, specifically, processes for making a catalyst for biomass conversion are provided. The process includes: treating a ZSM-5 zeolite with a phosphorous-containing compound to form a phosphorous-promoted ZSM-5 component; preparing a slurry comprising the phosphorous-promoted ZSM-5 component and a silica-containing binder; and shaping the slurry into shaped bodes. Such catalysts can be used for the Thermocatalytic conversion of particulate biomass to liquid products such as bio-oil, resulting in higher bio-oil yields and lower coke than conventional catalysts.

Catalyst for thermocatalytic conversion of biomass to liquid fuels and chemicals

A metal contaminated spent catalyst or regenerated catalyst from a biomass conversion unit may be subjected to an ammonium wash in order to remove potassium. The ammonium wash may include ammonium sulfate, ammonium nitrate, ammonium hydroxide, ammonium acetate, ammonium phosphates, and mixtures thereof. Acidity and catalytic activity of the biomass conversion catalyst is restored by the removal of potassium contaminants.

Process of reactivating a metal contaminated biomass conversion catalyst

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.

Phosphorous promotion of zeolite-containing catalysts

Disclosed are catalyst compositions including zeolite and silica components, methods of making, and processes of using in the thermo-catalytic conversion of biomass. Such disclosed methods of making include: i) spray drying of the catalyst precursor slurry at a pH below 1, or ii) the removal of ions such as sodium from the binder material prior to spray drying the catalyst precursor slurry at a pH below 2.7, or iii) spray drying the catalyst precursor including a pore regulating agent followed by steam treating, or iv) some combination of i), ii) and iii).

Catalysts for thermo-catalytic conversion of biomass, and methods of making and using

Catalyst compositions comprising a phosphorous-promoted ZSM-5 component and a silica-containing binder, and methods for making and using same, are disclosed. More specifically, processes for making a catalyst for biomass conversion are provided. The process includes: treating a ZSM-5 zeolite with a phosphorous-containing compound to form a phosphorous-promoted ZSM-5 component; preparing a slurry comprising the phosphorous-promoted ZSM-5 component and a silica-containing binder; and shaping the slurry into shaped bodies. Such catalysts can be used for the thermocatalytic conversion of particulate biomass to liquid products such as bio-oil, resulting in higher bio-oil yields and lower coke than conventional catalysts.

Process for converting biomass to a fuel

The present invention pertains to an improved nozzle, particularly for use in wear-resistant rotary atomizers, to atomizer wheels containing such improved nozzles and to a method for obtaining microspherical particles with a narrower particle size distribution when using such nozzles. The atomizer wheels and nozzles have at least the same wear resistance as those described in the prior art, but have been improved to provide microspherical particles with a very narrow particle size distribution. The nozzle of the present invention comprises a flow channel in the shape of a vertical slot that may be lined with wear-resistant sintered material. The vertical slot may be uniformly rounded. It was found that when these improved nozzles are used for spray-drying suspensions, microspherical particles with a narrower particle size distribution are obtained than when using nozzles with cylindrical flow channels.
