Biomass (e.g., plant biomass, animal biomass, and municipal waste biomass) is processed to produce useful intermediates and products, such as energy, fuels, foods or materials. For example, systems and methods are described that can be used to treat feedstock materials, such as cellulosic and / or lignocellulosic materials, in a vault in which the equipment is protected from radiation and hazardous gases by equipment enclosures. The equipment enclosures may be purged with gas.

A process for reducing the naphthenic acidity of petroleum oils or their fractions is described, said process comprising providing a hydrocarbon feed 103 / 203 / 303 having between 0.1 and 99 wt % of emulsified / dispersed water in oil, said feed containing salts and a content of naphthenic acids measured as TAN between 0.1 and 10 mg KOH / g oil; directing the said petroleum oil feed and emulsified / dispersed water towards an energy emitter device in the microwave range and submitting said feed 103 / 203 / 303 in liquid phase, under pressure between 0.7 and 4.5 MPa at temperatures between 50° C. and 350° C. to the microwave radiation, applied in the range of 1 mm to 30 cm to said feed so that the presence of salts, the applied temperature and the high dielectric constant of the water droplets make that the heat is absorbed on the spot by the water and heat said water preferentially to the oil, while the naphthenic compounds at the interface between the droplets and the oil catch said heat; effecting the decomposition of the carboxylic acids responsible for the naphthenic acidity in the petroleum feed at temperatures around 320° C. and generating CO2; separating with the aid of any known device 106 / 106′ / 112 / 117 / 208 / 208′ / 214 / 219 / 310 / 310′ / 316 / 321 any gas phase generated, water and oil; and recovering the hydrocarbon oil stream 108 / 113 / 119 / 210 / 215 / 221 / 312 / 317 / 323 having a reduced content in naphthenic acids. The process is designed to be applied to the reduction of naphthenic acids in feeds of petroleum oils and their fractions in the oil production step, in refineries or any industrial installation.

A hybrid fuel includes blends of biofuel emulsions and liquid fuel products, including light gas diesel. Optionally, the hybrid fuel can include water, oxygenate additives, and other additive packages.

The present invention is drawn to a method of processing heavy paraffinic oils or heavy aromatic oils using radiation chemistry of polyethylene under oxidizing conditions. The process of the invention will result in a chain reaction for oxidative scission as the basis for a radiation processing for heavy paraffinic or aromatic oils. The method of the invention will allow for the cost-efficient and environmentally-friendly processing of heavy oils into lighter petroleum products.

The invention provides a method for removing a water-soluble polymer in polymer-bearing crude oil. The method comprises the following steps: uniformly adding a barium carbonate particle into the polymer-bearing crude oil, then radiating the obtained crude oil mixture in a microwave environment and carrying out filtering so as to effectively remove the water-soluble polymer in the polymer-bearing crude oil. The objective of the invention is to provide the method for removing the water-soluble polymer in the polymer-bearing crude oil to overcome the problems of difficult demulsification of the polymer-bearing crude oil produced after polymer flooding on the ground and during transporting, reduced efficiency of a heater, high cost of a de-emulsifier and the like. The method can remove the water-soluble polymer in the polymer-bearing crude oil and has the advantages of easiness in operation and realization and low cost; the barium carbonate particle used in the invention has the characteristics of regeneration performance and repeated usability, so cost of the method is reduced; and the method is applicable to technological treatment of polymer-bearing crude oil produced from a polymer flooded oil reservoir.

Methods and systems relate to treating an oil-in-water emulsion with an electron beam to decrease aromatic content therein for subsequent recovery of diesel products with upgraded cetane number. The method includes passing the emulsion formed of water and a hydrocarbon stream, such as light cycle oil, through an electron beam. The electron beam causes radiolysis of the water into intermediates that react with and open rings of aromatic compounds from the hydrocarbon stream. Separation of the water from the emulsion after the treating with the electron beam provides the diesel products, which may be hydroprocessed to remove oxygenates.
