The present invention relates to a process for production of anisotropic coke from a hydrocarbon feedstock and a system for producing the same. More particularly, the present invention relates to a thermal cracking of heavy petroleum residue producing petroleum coke and lighter hydrocarbon products. The invented process utilizes a novel scheme for production of a premium quality coke from primarily, a clarified oil feedstock. Clarified oil from fluid catalytic cracking unit is routed through a process scheme comprising a separator column, hydrotreatment section and an aromatic extraction section to create an ad-mix of effluents which form the feedstock to a thermal cracking unit. Premium quality anisotropic coke is produced in the thermal cracker reactor drums under tailor made process conditions employing the said feedstock.

Process for production of anisotropic coke

A distribution unit for distributing a multi-phase fluid mixture is disclosed. The distribution unit includes a distribution body defining a first passage, and a first distal body portion having a plurality of first slots. The distribution body includes a second distal body portion having a plurality of second slots distributed on a side wall of the second distal body portion. Each of the plurality of second slots is adapted to accommodate a baffle plate. The second distal body portion includes at least one aperture formed on a bottom wall of the second distal body portion. The plurality of first slots, the plurality of second slots, and the at least one aperture are in fluid communication with the first passage to discharge the flow of the multi-phase fluid.

This invention relates to a process for hydro cracking of heavy oils. More particularly, this invention relates to a catalytic process for converting heavy oils, such as vacuum gas oil (VGO) and VGO containing a high proportion of vacuum resid (VR) to middle distillate products.

The present invention relates to a hydrocracking reactor system and a process utilizing the same for upgrading heavy hydrocarbonaceous material to value-added products. Accordingly, an aspect of the present invention includes dispersing a liquid feedstock pre-mixed with a catalyst from top of a reactor vessel to obtain dispersed droplets having a predetermined droplet size less than 500 &#x3bc;m, introducing a gaseous feed comprising primarily of hydrogen from bottom of the reactor vessel to form a continuous gaseous phase throughout a cross-section of the reactor vessel, and allowing the dispersed droplets to contact the continuous gaseous phase throughout the cross-section of the reactor vessel to form reaction effluent comprising one or more lighter product hydrocarbons. The method may further include removing at least a top portion and at least a bottom portion of the reaction effluent from the reactor vessel.

Reactor system and process for upgrading heavy hydrocarbonaceous material

The present invention discloses a catalyst and process for hydrocracking of heavy hydrocarbon oils having majority portion boiling above 525&#xb0; C. in the presence of hydrogen. A process comprising first step of converting heavy oil into lighter products in the presence of catalyst and hydrogen in slurry phase is disclosed. The process further comprises recycling of part of liquid products (HVGO) along with fresh heavy oil for improving the product selectivity. This recycled HVGO is having high concentrations of aromatics compounds. The separation of particles generated during the reaction at reactor exit also avoids the chances of choking of downstream sections.
