In this disclosure, a reactor system is described. The reaction system comprises (a) a reaction vessel having an inner wall, wherein said reaction vessel is configured to receive reactants and export products and byproducts; (b) a primary quench device (PQD) configured to receive a coolant and disperse said coolant into said reaction vessel; and (c) a secondary quench device (SQD) configured to receive a coolant and disperse said coolant into said reaction vessel; wherein said PQD comprises an array of spray nozzles fixed on the inner wall of said reaction vessel at a first axial position; and wherein said SQD comprises (1) an axially movable pipe having a coolant entry end and a nozzle end, wherein said pipe is configured to be removably fixed inside said reaction vessel; and (2) a spray nozzle that is fluidly connected to said pipe at its nozzle end via a fluid tight seal connection.

Secondary reaction quench device and method of use

A process for converting natural gas to a hydrocarbon liquid wherein a stream of natural gas at a selected pressure is mixed with a hot gas stream which is at a temperature sufficient to affect a chemical reaction and form an intermediate product stream containing reactive hydrocarbons, the intermediate product stream being quenched and the quenched intermediate product stream being reacted in a catalytic liquification zone to produce a hydrocarbon liquid.

High temperature hydrocarbon cracking

An improved process for the conversion of normally gaseous methane-containing hydrocarbon mixtures, such as natural gas, to a normally liquid hydrocarbon product comprises separating the methane component of the gaseous mixture from the heavier hydrocarbon component, cracking the separated heavier: hydrocarbon component at a relatively low temperature and optionally cracking the methane component at a relatively high temperature. The low temperature cracking product and any high temperature cracking product are separated into a light product of principally hydrogen and a heavy product comprising unsaturated hydrocarbons. This heavy product is reacted with methane in the presence of an acidic alkalization catalyst. The resulting product mixture is separated into a light product, a portion of which is recycled, and the normally liquid hydrocarbon product.
