The invention is directed to a process to prepare a char product and a syngas mixture comprising hydrogen and carbon monoxide from a solid torrefied biomass feed comprising the following steps: (i) subjecting the solid biomass feed to a pyrolysis reaction thereby obtaining a gaseous fraction comprising hydrogen, carbon monoxide and a mixture of gaseous organic compounds and a solid fraction comprising of char particles; (ii) separating the char particles as the char product from the gaseous fraction; (iii) subjecting the gaseous fraction obtained in step (ii) to a continuously operated partial oxidation to obtain a syngas mixture further comprising water and having an elevated temperature and (iv) contacting the syngas mixture with a carbonaceous compound to chemically quench the syngas mixture. The temperature of the syngas is reduced in step (iv) from between 1000 and 1600 C. to a temperature of between 800 and 1200 C.

According to an embodiment of the present disclosure, petrochemicals may be produced from crude oil by a process which includes passing the crude oil and hydrogen into a hydroprocessing reactor, separating the hydrotreated oil into a lesser boiling point fraction and a greater boiling point fraction, passing the lesser boiling point fraction to a pyrolysis section of a steam cracker to produce a pyrolysis effluent comprising olefins, aromatics, or both, passing the greater boiling point fraction to a gasifier, where the gasifier produces hydrogen, and passing at least a portion of the hydrogen produced by the gasifier to the hydroprocessing reactor.

A burner for producing synthesis gas by partial oxidation of liquid or gaseous, carbon-containing fuels in the presence of an oxygen-containing oxidant and a moderator, which burner can be operated uncooled, i.e. without a fluid coolant being passed through the burner, is proposed. Steam or carbon dioxide or else mixtures of these materials are used as moderator. This is achieved by the feed channels being configured so that mixing of the fuel, the moderator and the oxidant occurs only outside the burner.

Process for manufacturing a hydrogen-containing synthesis gas from a natural gas feedstock, comprising the conversion of said natural gas into a raw product gas and purification of said product gas, the process having a heat input provided by combustion of a fuel; said process comprises a step of conversion of a carbonaceous feedstock, and at least a portion of said fuel is a gaseous fuel obtained by said step of conversion of said carbonaceous feedstock.

Disclosed is a process for the concurrent production of hydrogen and sulphur from a H.sub.2S-containing gas stream, with zero emissions. The method comprises the thermal oxidative cracking of H.sub.2S so as to form H.sub.2 and S.sub.2. Preferably, the oxidation is conducted using oxygen-enriched air, preferably pure oxygen. The ratio H.sub.2S/O.sub.2 in the feedstock is higher than 2:1, preferably in the range of 3:1-5:1.

A process for the manufacture of a useful product from carbonaceous feedstock of fluctuating compositional characteristics, comprising the steps of: continuously providing the carbonaceous feedstock of fluctuating compositional characteristics to a gasification zone; gasifying the carbonaceous feedstock in the gasification zone to obtain raw synthesis gas; recovering at least part of the raw synthesis gas from the gasification zone and supplying at least part of the recovered raw synthesis gas to a partial oxidation zone; equilibrating the H.sub.2:CO ratio of the raw synthesis gas in the partial oxidation zone to obtain equilibrated synthesis gas; recovering at least part of the equilibrated synthesis gas from the partial oxidation zone and treating the gas to remove impurities and generate a fine synthesis gas; and converting the optionally adjusted fine synthesis gas into the useful product in a further chemical reaction requiring a usage ratio.

Syngas is alternatingly introduced by a syngas alternating lead-in system through either of one- and the other-end-side heat storage bodies into flow passages in a primary reforming furnace, and oxidant is alternatingly supplied to the syngas by a primary-oxidant alternating supply system. The syngas derived from the primary reforming furnace by a syngas alternating lead-out system is introduced into a secondary reforming furnace to which connected is a secondary-oxidant supply system for supply of oxidant only at alternation in the syngas alternating lead-in and -out systems.
