Abstract:
A process for stabilizing pyrolysis oil has been developed. The process involves heating the pyrolysis oil at a temperature of about 40°C to about 85°C under a reducing atmosphere for a time to stabilize the oil. The reducing atmosphere or gas is preferably hydrogen.
Abstract:
A process for the conversion of biomass derived pyrolysis oil to liquid fuel components is presented. The process includes the production of diesel, aviation, and naphtha boiling point range fuels or fuel blending components by two-stage deoxygenation of the pyrolysis oil and separation of the products.
Abstract:
A method of determining a surface property, eg, porosity, pore size, pore density, pore volume, pore shape, adsorption, desorption, adsorption selectively, of solids in a plurality by contacting the solids with a fluid, measuring the radiation emitted, absorbed, or altered during adsorption of the fluid using a detector, and then determining at least one surface property of the solids from the radiation measurements has been invented. The invention is particularly useful in combinatorial applications in order to evaluate a plurality of solids or mixtures of solids to determine at least one surface property of each of the solids and to sequentially expose each of the solids to different adsorbates.
Abstract:
Processes for partially deoxygenating a biomass-derived pyrolysis oil to produce a fuel for a burner. A biomass-derived pyrolysis oil stream is combined with a low recycle stream that is a portion of a deoxygenated effluent to form a heated diluted py-oil feed stream, which is contacted with a first deoxygenating catalyst in the presence of hydrogen at first hydroprocessing conditions effective to form the effluent stream. The effluent may be separated and used to provide a product fuel stream for a burner.
Abstract:
Un método para formar un aceite (38) de pirólisis derivado de biomasa de bajo contenido metálico, comprendiendo el método las operaciones de: filtrar un aceite (12) de pirólisis derivado de biomasa con una disposición (20) de filtro de caudal elevado que tiene un diámetro de poro de filtro de 50 μm o mayor con un caudal de desde 200 L/m2/h a 500 L/m2/h para formar un aceite (22) de pirólisis derivado de biomasa de bajo contenido en sólidos; filtrar el aceite (22) de pirólisis derivado de biomasa de bajo contenido en sólidos con una disposición (28) de filtro fino que tiene un diámetro de poro de 50 μm o menos para formar un aceite (30) de pirólisis derivado de biomasa de contenido en sólidos muy bajo; y poner en contacto el aceite (30) de pirólisis derivado de biomasa de contenido en sólidos muy bajo con una resina de intercambio de iones para eliminar iones metálicos y formar el aceite (38) de pirólisis derivado de biomasa de bajo contenido metálico.
Abstract:
METHODS FOR PRODUCING LOW OXYGEN BIOMASS-DERIVED PYROLYSIS OIL ARE PROVIDED. STARTING BIOMASS-DERIVED PYROLYSIS OIL IS DEOXYGENATED BY EXPOSING THE BIOMASS-DERIVED OIL TO A FIRST CATALYST IN THE PRESENCE OF HYDROGEN-CONTAINING GAS AT FIRST HYDROPROCESSING CONDITIONS TO PRODUCE A PARTIALLY DEOXYGENATED BIOMASS-DERIVED PYROLYSIS OIL. THE FIRST CATALYST HAS A NEUTRAL CATALYST SUPPORT. THE PARTIALLY DEOXYGENATED BIOMASS-DERIVED PYROLYSIS OIL IS EXPOSED TO A SECOND CATALYST IN THE PRESENCE OF ADDITIONAL HYDROGEN-CONTAINING GAS AT SECOND HYDROPROCESSING CONDITIONS TO PRODUCE A HYDROCARBON PRODUCT. THE BIOMASS-DERIVED PYROLYSIS OIL MAY BE ESTERIFIED PRIOR TO DEOXYGENATION. A PORTION OF THE LOW OXYGEN BIOMASS-DERIVED PYROLYSIS OIL IS RECYCLED. THE MOST ILLUSTRATIVE DRAWING IS
Abstract:
LOW METAL BIOMASS-DERIVED PYROLYSIS OILS AND PROCESSES FOR PRODUCING THE SAME ARE PROVIDED. LOW METAL BIOMASS-DERIVED PYROLYSIS OIL IS PRODUCED BY A PROCESS OF CONTACTING METAL-CONTAINING BIOMASS-DERIVED PYROLYSIS OIL WITH AN ACIDIC ION-EXCHANGE RESIN HAVING SULFONIC ACID GROUPS. LOW METAL BIOMASS-DERIVED PYROLYSIS OIL IS REMOVED FROM SPENT ACIDIC ION-EXCHANGE (STEP 16) RESIN AFTER ION-EXCHANGE.
