Ethylene is a key building block of the chemical industry and is used in the production of many products including plastics. Over 150 million tonnes of ethylene are produced per annum, more than any other organic compound. Traditionally it is obtained by the highly energy intensive process of oil cracking in ‘naptha crackers’. The environmental lobby is exerting extreme pressure on these plants, calling for their closure. The search is on for new processes.


We are developing technology using methane as a feedstock. This is highly desirable due to the dramatic increase in the availability of methane, driven by the continuous reduction of gas flaring and the exploitation of shale gas by hydraulic fracturing (fracking). Natural gas, whose main component is methane, is an abundant hydrocarbon source compared to crude oil and there is great interest in producing higher value bulk chemicals from it.

The oxidative coupling of methane (OCM) offers an economically viable route for ethylene production. Employing OCM with a new breed of reactor design produces dramatic cost reductions whilst providing an economically viable and environmentally friendly route for the production of ethylene. We use state-of-the-art catalytic membrane reactors, employing hollow fibre oxygen transport membranes. Under operation, oxygen from the air outside the reactor interacts with the membrane surface creating oxygen ions which are transported across the membrane. This delivers a source of pure oxygen to the reactor interior where it meets an incoming stream of methane. The catalyst inside the reactor facilitates the coupling of methane to yield ethylene product.


Finden works with leading companies and research institutions to demonstrate and scale-up this technology. We are are resolving chemical processes taking place within working reactor units and where problems such as deactivation occur, Finden finds solutions to overcome barriers to operation. Results in brief can be found at More details about the project can be found on the Memere website.
