The Aquaconversion technology is an extended catalytic visbreaking process in the presence of steam. The old visbreaking technology is limited in conversion level because of the stability of the resulting product.... The Aquaconversion process pushes this maximum conversion level within the stability specification by adding a homogeneous catalyst in the presence of steam. This novel catalytic system allows hydrogen from the water to be transferred to the resid when contacted in a coil-soaker system normally used for the visbreaking process.  2, record 2, English, - aquaconversion

Heterogeneous catalysts, in contrast to homogeneous catalysts, form a separate phase from reactants and products and are usually solids. They have a microporous structure and a very large internal surface area(it may reach 1000 m²/g) but these colloidal catalysts are often inactivated by the presence of small amounts of poisons. Poisons act by combining with an active site in the catalyst surface and rendering it inactive.  2, record 3, English, - homogeneous%20catalyst
