Abstract: Disclosed is a hydrocarbon conversion process that is less energy intensive than comparable processes. The hydrocarbon conversion process is particularly desirable for converting alkanes, such as methane into C2+ olefins, such as ethylene and propylene, particularly with increasing selectivity to ethylene production. It is also desirable for effectively removing a C2 composition (i.e., ethane, ethylene and/or acetylene) produced from the catalytic conversion of hydrocarbon comprised of C2+ olefins. In addition, the hydrocarbon process is desirable for providing a substantially non-cryogenic separation of the desired C2 compositions from the hydrocarbons (e.g., methane) present in the reaction mixture.

Abstract: The present invention is directed to a combination reactor system for exothermic reactions comprising a trickle-bed reactor and a shell-and-tube reactor. This combination allows the system to efficiently remove heat while also providing the ability to control both the temperature and/or reaction progression. The trickle-bed reactor removes heat efficiently from the system by utilizing latent heat and does not require the use of a cooling or heating medium. The shell-and-tube reactor is used to further progress the reaction and provides a heat exchanger in order to introduce fluid at the desired temperature in the shell-and-tube reactor. Also, additional reactant or reactants and/or other fluids may be introduced to the shell-and-tube section of the reactor under controlled temperature conditions.
