Process and device for manufacturing synthesis gas and application

The present invention relates to a process and a device for manufacturing synthesis gas. The reactor according to the invention comprises within a single housing: A non catalytic combustion chamber (1) comprising at least one device (2) for injecting a fuel and at least one device (3) for injecting an oxidizer so as to achieve a partial combustion in said chamber, and at least one catalytic bed (4) which the gases coming from combustion chamber (1) run into, and also comprising at least one device (6) for injecting an additional oxidizer. The reactor and the process according to the invention may be applied to any chemical manufacturing utilizing synthesis gas, such as the manufacturing of ammonia, urea, methanol, higher hydrocarbons, etc.

A reactor for manufacturing synthesis gas as a single housing, equipped with a non-catalytic combustion chamber having at least one device for injecting a fuel and at least one device for injecting an oxidizer so as to achieve partial combustion in said chamber, and at least one catalytic bed from which the gases coming from the combustion chamber discharge into, said catalytic bed being equipped with at least one device for injecting an additional oxidizer. A process for operating the reactor may be applied to any chemical manufacturing utilizing synthesis gas, such as the manufacturing of ammonia, urea, methanol, higher hydrocarbons, etc.

The present invention relates to a device and a process for manufacturing synthesis gases through the combustion, under lack of oxygen, of a hydrocarbon fuel by use of a gaseous oxidizer, the device comprises primary injection means (2) producing, following an axis (14), a jet of fuel and of part of the oxidizer in a combustion chamber of a reactor, said jet comprising a main flame substantially originating at the level of the primary injection means (2) and extending from the primary injection means. The device also includes secondary injection means for injecting a complementary amount of oxidizer into the combustion chamber, the secondary injection means being arranged to direct the complementary amount of oxidizer into the jet at a distance from the primary injection means.

Device and process for manufacturing synthesis gases through combustion

The present invention provides a burner for a reactor producing synthetic gas for conveying at least two fluids separately to a reaction zone, one serving as fuel and the other as combustive. It comprises a solid element in which are provided holes penetrating to different depths, these holes opening at one of their ends into the reactor and at the other either into fuel supply means or into combustive supply means depending on the fluid conveyed by the hole considered.

Burner for the manufacture of synthetic gas comprising a solid element

A method and device are provided for producing synthetic gas by combustion of a fuel in a combustive agent deficient atmosphere, said combustive agent being gaseous, said device including first means for feeding the fuel and a part of the combustive gas into the reactor, and second means for feeding a second part of the combustive gas into the reactor, said second means including a porous wall defining at least a part of said reactor.

Device using a flame for producing synthetic gas

The present invention provides a burner for the partial oxidation under pressure of a first fluid by the second fluid. This burner comprises two fluid introduction tubes, one being internal to the other, with each of the tubes comprising a plate, and with each plate having several holes and a plate of the external tube has holes placed opposite the holes in the internal plate.

Partial oxidation burner for producing synthetic gases

The invention concerns a process for manufacturing a composition of fatty acid esters useful as gas oil substitute motor fuel, said composition containing at least one hydrated ethyl alcohol. The process comprises:
