Methods for the production of carbon black using an extender fluid(s) are provided as well as methods to control one or more particle properties of carbon black utilizing extender fluids and other techniques.

Method for producing carbon black using an extender fluid

Methods for production of carbon black using high temperature feedstock at temperatures exceeding about 300&#xb0; C. with fouling control are provided. An apparatus for production of carbon black according to these methods also is provided.

Method for carbon black production using preheated feedstock and apparatus for same

A power generation system and method in which a fuel gas is introduced into a combustor and at least a portion of the fuel gas is combusted in the combustor, producing an exhaust gas having no appreciable available oxygen. The exhaust gas is introduced as a working fluid into a gas turbine, thereby generating power. Cooling of the power generation system is accomplished using a cooling fluid selected from the group consisting of synthesis gas, natural gas, natural gas/steam mixture, flue gas, flue gas/steam mixture, and mixtures thereof.

Partial oxidation gas turbine cooling

A method and system for producing synthesis gas in which a carbonaceous material and at least one oxygen carrier are introduced into a non-thermal plasma reactor at a temperature in the range of about 300&#xb0; C. to about 700&#xb0; C. and a pressure in a range of about atmospheric to about 70 atmospheres and a non-thermal plasma discharge is generated within the non-thermal plasma reactor. The carbonaceous material and the oxygen carrier are exposed to the non-thermal plasma discharge, resulting in the formation of a synthesis gas in the non-thermal plasma reactor.

Plasma assisted conversion of carbonaceous materials into synthesis gas

A method and system for producing product gases in which a carbonaceous material and at least one oxygen carrier are introduced into a non-thermal plasma reactor at a temperature in the range of about 300&#xb0; C. to about 700&#xb0; C. and a pressure in a range of about atmospheric to about 70 atmospheres and a non-thermal plasma discharge is generated within the non-thermal plasma reactor. The carbonaceous material and the oxygen carrier are exposed to the non-thermal plasma discharge, resulting in the formation of a product gas in the non-thermal plasma reactor, which product gas comprises substantial amounts of hydrocarbons, such as methane, hydrogen and/or carbon monoxide.

Plasma assisted conversion of carbonaceous materials into a gas

A two-stage power generation system having a compressed air source with two compressed air outlets, one of which provides compressed air to the first stage of power generation and the other of which provides compressed air to the second stage of power generation. All of the fuel for the two-stage power generation system is introduced into the first stage. Exhaust gases from the first stage are introduced into a fuel inlet of the second stage of power generation. The first stage preferably includes a gas turbine operated in partial oxidation mode. The exhaust gases from the partial oxidation gas turbine contain thermal and chemical energy, both of which are used in the second stage.

Air-staged reheat power generation system

A method and apparatus for combustion of a fuel in which a first-stage fuel and a first-stage oxidant are introduced into a combustion chamber and ignited, forming a primary combustion zone. At least about 5% of the total heat output produced by combustion of the first-stage fuel and the first-stage oxidant is removed from the primary combustion zone, forming cooled first-stage combustion products. A portion of the cooled first-stage combustion products from a downstream region of the primary combustion zone is recirculated to an upstream region of primary combustion zone. A second-stage fuel is introduced into the combustion chamber downstream of the primary combustion zone and ignited, forming a secondary combustion zone. At least about 5% of the heat from the secondary combustion zone is removed. In accordance with one embodiment, a third-stage oxidant is introduced into the combustion chamber downstream of the secondary combustion zone, forming a tertiary combustion zone.
