Process and a system for producing synthesis gas
The present disclosure relates to a process and a system for producing synthesis gas. The carbonaceous feedstock is gasified, in the presence of at least one of oxygen and steam, in a first reactor to obtain a gaseous mixture comprising H2, CO, CH4, CO2, H2O, tar and char. The gaseous mixture is treated in a second reactor, in the presence of a catalyst, to obtain synthesis gas.

PROCESS FOR PRODUCTION OF AROMATICS VIA PYROLYSIS OF LIGNIN-COMPRISING MATERIAL
This invention relates to a process for the conversion of a feedstock comprising a lignin-comprising material, comprising the steps (a) to (c): (a) charging the feedstock to a fluidized bed reactor; (b) pyrolyzing at least part of the feedstock in the fluidized bed reactor while introducing a carrier gas into the reactor, to produce pyrolysis vapours; (c) reacting at least part of the pyrolysis vapours coming from step (b) in a second reactor comprising a catalyst, to produce hydrocarbon products comprising aromatics.
PYROLYSIS OIL AND METHOD AND SYSTEM FOR THE PRODUCTION THEREOF
A method for producing a pyrolysis oil is described. In said method, a feedstock to be treated is first pyrolyzed in a pyrolysis zone, in which the feedstock is heated to a temperature of 250 degrees Celsius to 700 degrees Celsius; and pyrolyzed solids and pyrolysis vapors are formed. The pyrolysis vapors are then reformed at a temperature of 450 degrees Celsius to 1,200 degrees Celsius in a post-conditioning zone, in which the pyrolysis vapors are brought into contact with a catalyst bed, wherein the pyrolysis oil is formed. In this case, the catalyst comprises a pyrolyzed solid, which can be obtained according to the pyrolysis, described above. Finally the pyrolysis oil is separated from the additional pyrolysis products, which are formed, in a separation unit.
FLEXIBLE PROCESS FOR CONVERTING CARBON DIOXIDE, HYDROGEN, AND METHANE INTO SYNTHESIS GAS
The present invention relates to a process for converting feed streams selected from (1) a gas stream comprising carbon dioxide and a hydrogen rich gas stream; (2) a methane rich gas stream; and (3) a combination of feed streams (1) and (2) into a product stream comprising carbon monoxide, water and hydrogen. The process may include introducing feed streams selected from (1), (2) or (3) and oxygen into a reaction vessel and switching modes between performing method I or method II in the reaction vessel wherein no catalyst is present. The reaction vessel may be provided with a burner located at the top of the reaction vessel, the burner may include coaxial channels for the separate introduction of the different gas streams. Method I may be a reverse water gas shift reaction at elevated temperature. Method II may be a partial oxidation reaction at elevated temperature.
SYSTEM FOR, METHOD OF, AND THE RESULTING PRODUCT OF THE PRODUCTION OF FUEL GAS, HEAT AND ELECTRICITY
Traditional residential and industrial furnace systems convert the chemical energy of liquid and gas fuels into thermal energy and, in some earlier applications, also into electric energy. This process is driven by a burner specifically designed and built. Often these systems operate at high temperatures, high pressures and relatively lower efficiency levels. The field of present invention generally relates to furnaces that combine the fuel production to the both thermal either electrical energy production. More particularly, the present invention produces a combustible gas that, within the internal workings of the present invention, and can efficiently be burned without the production of high levels of pollutants, at relatively lower temperatures and pressures. The foregoing characteristics, along with the limited size of the elements needed to practice the present invention, make it conducive for use as and in connection with, among other things, residential furnaces and other heating systems, including, for example, heat exchangers and residential hot water tanks. In short, the present invention involves the production of a combustible fuel gas, thermal and electric energy. This production is accomplished through the interconnected use of water electrolysis, catalysts, storage means, regulation, and mean of reusing materials to increase production efficiencies.
