To improve paraffin Houdry� dehydrogenation technology a new Heat Generating Material (HGM) concept was developed for conducting non-oxidative dehydrogenation. This concept takes advantage of the cyclic red-ox operating mode of the technology and combines it with the heat production method known as a chemical-looping combustion. This has been implemented by mixing Al-Cr dehydrogenation catalyst with a Heat Generating Material (HGM), which contains a metal oxide. During the reduction part of the cycle, the metal oxide is reduced producing heat (reaction 1). During the regeneration part of the cycle the metal is re-oxidized by oxygen and provides an additional amount of heat (reaction 2). Extensive study of HGM concept application in non oxidative dehydrogenation showed that it allows significant increase of the production rate by increasing paraffin conversion; significant increase of the olefin selectivity and minimize energy consumption. At this point, the HGM concept has been proven on the commercial scale.
