Abstract:
A method is disclosed for removing Se(IV) from aqueous solutions. The method begins by oxidizing an aqueous selenium solution with an aqueous oxidant to produce a Se(IV) solution. The Se(IV) solution is then contacted with a solid sorbent. The Se(IV) from the Se(IV) solution is then simultaneously adsorbed and encapsulated onto the solid sorbent to form an exhausted sorbent. The exhausted solid sorbent can then be disposed.
Abstract:
A process of mixing methyldiethanolamine to water to produce a first mixture. 2-amino-2-methyl-1-propanol is added to the first mixture to form a second mixture. The second mixture is then heated while mixing to form a third mixture. Piperazine is then added to the third mixture to form a solvent.
Abstract:
A process of polymerizing formula f with formula g and formula h wherein the stoichiometric ratio of f = (g+h) and f, g and h are not equal to 0. This process can also have R1 selected from the group consisting of alkyl group, alkoxy group, aryl groups and combinations thereof. Additionally, x and y can be different from each other.
Abstract:
The present disclosure relates to novel processes for making improved blends of hydrocarbon fuels that provide increased power and a broader operating range when used as fuel for homogeneous charge compression ignition engines.
Abstract:
The present embodiment describes a method of forming different layers in a solid oxide fuel cell. The method begins by preparing slurries which are then delivered to a spray nozzle. The slurries are then atomized and sprayed subsequently onto a support to produce a layer which is then dried. In this embodiment different layers can comprise an anode, an electrode and a cathode. Also the support can be a metal or a metal oxide which is later removed.
Abstract:
A process of producing degassed liquid sulfur within a vertical sulfur condenser may include providing a plurality of condenser tubes within an external casing; submerging exit ends of the plurality of condenser tubes within a liquid reservoir resulting in submerged exit ends of the plurality of condenser tubes; passing the Claus process gas into an inlet end of the plurality of condenser tubes; condensing the Claus process gas within the condenser tubes to produce condensed Claus process gas within the plurality of condenser tubes; and collecting the condensed Claus process gas in the liquid reservoir upon exiting of the condensed Claus process gas at an exit end of the plurality of condenser tubes.
Abstract:
A method of steam reforming where a reaction occurs in which an oxygenated feed contacts a catalyst to produce hydrogen. The catalyst of the reaction comprises a metal/metal promoter on a nickel/transition metal blend catalyst supported on a high-energy lattice metal oxide.
Abstract:
A process of producing a feed form a solid electrolyte oxygen separator and combusting the feed in a steam methane reforming furnace to produce a flue gas.
Abstract:
The present invention relates generally to the thermal conversion of biomass. Processes are disclosed for converting algal biomass to condensable vapor intermediates such as pyrolysis oil by means of pyrolysis in a reactor comprising at least one auger. The intermediates may be further processed for production of renewable hydrocarbon fuels. The disclosed processes assist in preventing premature devolatization of algal biomass during pyrolysis, thereby increasing efficiency and commercial feasibility.
Abstract:
An aqueous drag reducer comprising a poly(alpha olefin), a winterizing agent and water. In this embodiment the winterizing agent comprises at least about 30 wt% of the aqueous drag reducer. Additionally, water comprises less than about 2.0 times the amount of winterizing agent.
