In the past, there have been a number of semi-industrial trials and even commercial processes to obtain on-purpose petrochemical feedstocks from methane and/or propane (more generally, C1-C4 hydrocarbons). However, their commercial success has been limited due to several reasons: from technical drawbacks (low conversions and selectivity) to economics (high capital investment and high operation costs are often obtained). Furthermore there is a need for lowering the carbon footprint of gas and oil industry, i.e . refining industry, contributing to an evolving scenario of sustainable economy in such field.
