## Abstract

A process for the coupling of hydrocarbons and utilizing the heat energy produced by the reaction is disclosed. In one embodiment the process can include reacting methane with oxygen to form a product stream containing ethane and further processing the ethane to ethylene in an existing ethylene production facility while using the heat energy produced by the reaction within the facility.

## Claims

### Claim at position 1

1-21. (canceled)

### Claim 22

A process comprising:
an oxidative coupling reaction of hydrocarbons, wherein the oxidative coupling reaction includes the reaction of methane and toluene, isobutylene, t-butyltoluene, or trimethylbenzene;
wherein the oxidative coupling reaction is exothermic and generates heat energy;
wherein at least a portion of the heat energy generated by the oxidative coupling reaction is recovered and utilized in a facility.

### Claim 23 (depends on 22)

The process of claim 22, wherein at least a portion of the heat energy produced by the oxidative coupling reaction is recovered as steam and utilized in the facility.

### Claim 24 (depends on 23)

The process of claim 23, wherein the facility is an ethylene production facility.

### Claim 25 (depends on 22)

The process of claim 22, wherein the facility is an ethylene production facility.
