The present disclosure relates to a process for producing linear alpha olefins in high yield carried out by oligomerization of ethylene in the presence of a novel catalyst composition. The catalyst composition includes Zirconium compound, an organoaluminum compound, and at least one Lewis base selected from cyclic and acyclic ethers (i.e., di-n-butyl ether and diethyl ether). The process for oligomerization of ethylene is carried out in an inert organic solvent in the presence of said catalyst composition. The process as disclosed herein provides significantly high activity of the said catalyst composition resulting in high yield of the alpha olefins (>95 wt. %) as the product and significantly minimum polymer as by-product. The process provides higher yield of C6-C10 fraction with >60 wt. %.

The present invention relates to a process for preparation of a catalyst for polymerization of olefins. The catalyst has a particle size of between 5 to 30 microns with activity ranging from 3-4 Kg (co)polymer per g of catalyst and excellent hydrogen response. The method for preparation of the catalyst comprises the steps of: a) contacting a liquid magnesium complex, an electron donor, and a titanium halide compound to form a solution; b) obtaining the solid uniform catalyst particles by precipitation; and c) washing the catalyst particles to obtain solid uniform catalyst., for producing (co)polymer of ethylene with other olefins have fines less than 10 wt. %.

The present invention relates to a process for converting the waste plastic along with the petroleum residue feedstock in a Delayed Coker unit employed in refineries. The invented process aims to convert any type of waste plastic including polystyrene, polypropylene, polyethylene etc. including metal additized multilayer plastics along with the petroleum residue material from crude oil refining such as reduced crude oil, vacuum residue etc. Value added light distillate products like motor spirit, LPG, middle distillates etc. are produced upon co-conversion in the invented process and is recovered and treated along with the products of thermal cracking of hydrocarbon residues. The residual metals in the metal additized plastics upon co-conversion in the invented process will be deposited in the solid petroleum coke.

The present invention describes a catalyst composition for use as a catalyst system for an ethylene oligomerization, providing high activity and produce linear oligomer product having broad weight percent distribution i.e. Cto C. The catalyst composition comprises a zirconium amide compound, an organoaluminum compound and an additive. The present invention also provides a process for preparation of the zirconium amide compound comprising reacting a zirconium component having formula ZrX.nTHF, wherein X is halogen atom; m is an integer having value equal or less than 4 and n is a number equal or less than 2, and a substituted amide of formula RCONR'R&#x2033;, wherein R, R&#x2032; and R&#x2033; are saturated or unsaturated aliphatic C-Chydrocarbon or aromatic C-Chydrocarbon, in the presence of an organic solvent.

The present invention relates to a process for production of oligomer products from olefinic C4 feed stocks comprising isobutene, butenes, butanes, butadienes and mixture thereof. Particularly, the present invention relates to a process for the preparation of oligomers using olefinic C4 feed stock in presence of tertiary butyl alcohol (TBA) and iso propyl alcohol (IPA).

Process for simultaneous production of alcohols and oligomer product from hydrocarbon feed stock

The present invention provides a process for deep desulphurization of cracked gasoline with minimum octane loss of about 1-2 units. In this process full range cracked gasoline from FCC, Coker, Visbreaker etc is sent to Diolefin Saturation Reactor for selective saturation of diolefins. After saturation of diolefins, the stream is sent to Splitter for splitting into three cuts i.e Light Cut (IBP-70&#xb0; C.), Intermediate Cut (70-90&#xb0; C.) and Heavy Cut (90-210&#xb0; C.). The Light Cut which contains majority of the high octane olefins and mercaptan sulfur is desulfurized with caustic treatment using Continuous Film Contactor (CFC). The sulfur in the Intermediate Cut is also predominantly mercaptans and the cut can be desulfurized by caustic treatment using CFC along with Light cut or separately desulfurized before being sent for isomerization. The Heavy Cut containing mainly thiophinic sulfur compounds is treated either by using conventional HDS process or reactive adsorption process.
