Characterization of Asphaltenes in Solution and Inside the Pores of Catalysts by 1 H NMR Relaxometry

The upgrading of heavy petroleum fractions needs the development of more and more efficient heterogeneous catalysts. One of the major issues of these processes is the diffusion of asphaltenes to the active site through the porous network of the alumina support. The catalytic efficiency is deeply imp...
