Abstract: A reactor (12, 128, 198) and method for the conversion of hydrocarbon gases utilizes a reactor (12, 128, 198) having a unique feed assembly (58, 136, 200) with an original vortex disk-like inlet flow spaces (72, 74, 76, 80, 146, 148, 150, 152, 208, 216, 218), a converging-diverging vortex mixing chamber (116), and a cylindrical reactor chamber (40). This design creates a small combustion zone and an inwardly swirling fluid flow pattern of the feed gases that passes through a converging conduit (48) with a constricted neck portion (54). This provides conditions suitable for efficient cracking of hydrocarbons, such as ethane, to form olefins.

Abstract: The present invention provides a process for the manufacture of acetylene and other higher hydrocarbons from methane feed using a reverse-flow reactor system, wherein the reactor system includes (i) a first reactor and (ii) a second reactor, the first and second reactors oriented in a series relationship with respect to each other, the process comprising supplying each of first and second reactant through separate channels in the first reactor bed of a reverse-flow reactor such that both of the first and second reactants serve to quench the first reactor bed, without the first and second reactants substantially reacting with each other until reaching the core of the reactor system.

Abstract: A process for the preparation of acetylene and synthesis gas by partial thermal oxidation in a reactor which has a burner having passages, wherein the starting materials to be reacted are rapidly and completely mixed only immediately before the flame reaction zone in the passages of the burner, a mean flow rate which exceeds the flame propagation velocities under the given reaction conditions being established in the mixing zone within the passages.

Abstract: The invention relates to a process for the preparation of acetylene and synthesis gas by thermal treatment of a starting mixture containing one or more hydrocarbons and in addition molecular oxygen and/or one or more compounds containing the element oxygen, in which the starting mixture is heated, brought to reaction in a reactor and subsequently cooled. The process has the special feature that the starting mixture is heated to a maximum of 1400° C. It is then possible to carry out the process with comparatively little expenditure of energy.
