摘要： A process is described for producing synthesis gas and hydrogen starting from liquid hydrocarbon feedstocks, possibly also mixed with gaseous hydrocarbon streams, comprising at least the following operations: 1) nebulizing/vaporizing a stream of a liquid hydrocarbon feedstock consisting of one or more of the following hydrocarbons: naphthas, various kinds of gas oils, such as LCO, HCO and VGO, other products of refining cycles and oil up-grading, such as DAO, other heavy residues, at a N temperature ranging from 50 to 500° C. and a pressure of 2 to 50 atm, the nebulization also being effected with the help of a gaseous propellant, possibly with the addition of CO2, selected from vapour and/or a gaseous hydrocarbon and resulting in the formation of a nebulized/vaporized liquid hydrocarbon stream; 2) mixing the nebulized/vaporized liquid hydrocarbon stream coming from phase 1) with: a) an oxidizing stream, possibly mixed with vapour, b) possibly a gaseous hydrocarbon stream at a temperature ranging from 50 to 500° C. and a pressure of 2 to 50 atm, with the formation of a possibly biphasic liquid-gas reaction mixture; 3) passing the reaction mixture coming from phase 2) through at least a first structured catalytic bed with the formation of a mixture of reaction products comprising H2 and CO, said structured catalytic bed comprising a catalytic partial oxidation catalyst, arranged on one or more layers, the reaction mixture flowing through each of the layers with a contact time varying from 0.01 to 100 ms, preferably from 0.1 to 10 ms; 4) cooling the mixture of reaction products coming from phase 3). The relative equipment for effecting said process is also described.
