The present disclosure provides processes to convert paraffins to corresponding olefins and or heavier hydrocarbons. In at least one embodiment, a process includes introducing, at a temperature of from about 50 C. to about 500 C., a hydrocarbon feed comprising paraffins to a first metal oxide comprising one or more group 1 to group 17 metal and one or more oxygen. The process includes obtaining a product mixture comprising one or more C3-C50 cyclic olefins, one or more C2-050 acyclic olefins, one or more C5-C200 hydrocarbons, such as one or more C5-C100 hydrocarbons, or a mixture thereof. In at least one embodiment, the product mixture is substantially free of H2 (e.g., <500 ppm). The introducing can reduce the first metal oxide to form a second metal oxide. Processes may include introducing the second metal oxide to an oxidizing agent to form the first metal oxide.
