The technology relates to an upright tubular fixed-bed reactor body comprising a heat -dissipating pipe, which extends from the reactor tube wall, to ensure that heat is effectively transferred in highly exothermic reactors such as Ficher-Tropsch, which are prone to heat build-up. The heat pipe is

Hydrogen and fuel cell technologies offer zero emissions and are a clean alternative to fossil fuels. HySA Systems, at the University of the Western Cape, have made improvements in the performance, reliability and cost competitiveness of fuel cell components and systems. These have been demonstrated
