Process with improved productivity for the conversion of heavy oils
09884999 · 2018-02-06 ·

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.

Integrated fuel processing with biomass oil

A gas to liquids process with a reduced CO.sub.2 footprint to convert both natural gas and a renewable feedstock material into fuels or chemicals. In one embodiment of the invention, a natural gas feed is converted into synthesis gas containing hydrogen and carbon monoxide. A minor portion of the hydrogen is thereafter extracted from the synthesis gas. The synthesis gas is converted to hydrocarbons in a Fischer Tropsch reaction. The Fischer Tropsch hydrocarbon product and a renewable feedstock are hydroprocessed with the extracted hydrogen in order to produce fuels and/or chemicals. Waste products from the renewable feed are recycled to produce additional synthesis gas for the Fischer Tropsch reaction.

NANOCATALYST COMPOSITION, METHOD FOR MAKING NANOCATALYST COMPOSITION AND HYDROCONVERSION PROCESS USING SAME

A method for making a nanocatalyst includes the steps of forming a mixture of a catalyst precursor, and a crude oil media, wherein the catalyst precursor is insoluble in the oil media, then heating the mixture in the presence of a stability agent, thereby liberating the catalyst particles from the precursor while the stabilizing agent prevents growth of the catalyst particle so that nanocatalyst particles form and are maintained in the oil media. The resulting catalyst composition as well as a hydroconversion process using the catalyst are also disclosed.
