A catalytic hydrogen-aquathermolysis reactor receives a heavy oil feed, water and hydrogen. In addition catalytic materials and a viscosity reducing agent are introduced. The catalytic hydrogen-aquathermolysis reactor is operated at conditions effective to produce an upgraded heavy oil product.

A reactor and method for the conversion of hydrocarbon gases utilizes a reactor (12, 312, 412, 512, 612, 712) having a unique feed assembly with an original vortex combustion chamber (40, 340, 436, 536, 636, 736), a diverging conduit (48, 348, 448, 548, 648, 748), and a cylindrical reactor chamber (40, 340, 436, 536, 636, 736). This design creates a compact combustion zone and an inwardly swirling fluid flow pattern of the feed gases to form a swirling gas mixture that passes through a diverging conduit (48, 348, 448, 548, 648, 748). The feed streams can be introduced into the reactor at any angle (perpendicular, axial, or something between, or a combination of the above forms) with swirling flow components. This provides conditions suitable for efficient cracking of hydrocarbons, such as ethane, to form olefins.

The technology relates to a method of producing synthesis gas comprising carbon monoxide (CO) and hydrogen (H.sub.2), wherein the synthesis gas is produced by a reduction reaction of a first flow comprising a carbon source and an excess of hydrogen in contact with an Oxy-flame. The hydrogen comes from a reducing stream, a first portion of which ends up in the first flow, and a second part of which is used to generate the Oxy-flame by combustion of the hydrogen in the presence of a second flow comprising oxygen (O.sub.2), the second flow coming from an oxidizing stream. The first flow and the second flow are at a distance from each other such that the Oxy-flame supports the reaction between the carbon source and the hydrogen. A reactor, which can have different configurations, is also proposed for implementing the method.

A process including preheating a hydrocarbon feed in a first preheat zone of a convection section, recovering a preheated hydrocarbon stream; heating the preheated hydrocarbon stream in a secondary transferline exchanger, recovering a heated hydrocarbon stream; feeding the heated hydrocarbon stream to a second preheat zone of the convection section to vaporize a portion of heated hydrocarbon stream, recovering a cracking feedstream; cracking hydrocarbons in the cracking feedstream in one or more coils in a radiant section, recovering a cracked hydrocarbon product; and cooling the cracked hydrocarbon product in the secondary transferline exchanger in indirect heat exchange with the preheated hydrocarbon stream, recovering a cooled hydrocarbon product stream.

A process for producing hydrocarbons includes providing a component mixture containing hydrocarbons and a feed mixture containing hydrocarbons having two or more carbon atoms and lower boiling compounds using a portion of the component mixture, and forming a heavy fraction and a light fraction using the feed mixture. The heavy fraction contains a portion of the hydrocarbons from the feed mixture and is at least poor in the lower boiling components. The light fraction contains a portion of the lower boiling components from the feed mixture and is at least poor in the hydrocarbons from the feed mixture. The heavy fraction and a first intermediate fraction are formed using some of the feed mixture in low-temperature separation. Some of the first intermediate fraction is subjected to non-cryogenic separation while obtaining the light fraction and a second intermediate fraction. A portion of the second intermediate fraction is recycled to the process.
