The hydrogenation capacity of an upflow hydrocarbon hydrotreatment reactor is increased by expanding the gas-liquid contact surface.

Hydrotreatment upflow reactors with high hydrogen-hydrocarbon liquid contact surface and improved hydrogenation capacity

In the hydroconversion processes of heavy hydrocarbon oils, in which the hydrogen is introduced at the reactor base by bubbling, the low diffusion rate of hydrogen, from the gas phase to the reaction liquid, limits the degree of conversion. The process circumvents the obstacle of the limited amount of reactant hydrogen by using a slurry bubble column reactor which reduces the formation of light hydrocarbon products, and therefore the hydrogen required for the hydroconversion, allowing to operate at full conversion.

Process for the hydroconversion of heavy hydrocarbon oils with reduced hydrogen consumption operating at full conversion

Process for the complete conversion of heavy oils into distillates, such as the vacuum residues of heavy crude oils, characterized by the simultaneous use of two separate modes of extraction of the conversion products. Alongside the current mode of recovery of the conversion products, based on the treatment of the effluent of the top zone of the reaction, a second mode is added, based on the direct extraction of liquid from the reaction zone, degassing such liquid at the same pressure as the reactor and subjecting it to vacuum extraction. The vacuum residue is recycled in the reaction. The double mode of extraction allows greatly increasing the capacity of the reactor.

Process with improved productivity for the conversion of heavy oils

Provided is a system for the hydroconversion of heavy oils essentially consisting of a solid accumulation reactor and a stripping section of the products of hydroconversion outside or inside the reactor itself.

System and process for the hydroconversion of heavy oils

A process for the conversion of heavy feedstocks selected from heavy crude oils, distillation residues from crude oil or coming from catalytic treatment, visbreaker tars, thermal tars, bitumens from oil sands, liquids from coats of different origins and other high-boiling feedstocks of a hydrocarbon nature known as 'black oils.'

Process for the total conversion of heavy feedstocks to distillates

Process for the conversion of heavy feedstocks selected from heavy crude oils, distillation residues from crude oil or catalytic treatment, 'visbreaker tars', 'thermal tars', bitumens from &#x201c;oil sands&#x201d; liquids from coals of different origins and other high boiling feedstocks of a hydrocarbon origin.
