Disclosed herein is a method for biopile-based bioremediation of hydrocarbon waste with high aromatic content. The method comprises of isolating specific microorganisms and preparing microbial blend, preparing biopile, adding the microbial blend into the biopile, providing nutrient, aeration and watering of biopile.

Method for bioremediation of highly aromatic hydrocarbon wastes

Disclosed herein a process for upgrading the liquid hydrocarbon fuels by reducing aromatic content, sulfur content and nitrogen content wherein the process comprising isolating polycyclic aromatic hydrocarbon (PAH) transforming microbes and preparing biocatalyst by mutagenesis, contacting the biocatalyst with the liquid hydrocarbon fuel in an aqueous medium for transforming the aromatic, sulfur, and nitrogen containing compounds to polar substances, subjecting the mixture of biocatalyst and the liquid hydrocarbon fuel to a process of bioconversion, removing the polar substances by liquid-liquid extraction with a polar solvent to obtain dearomatized, desulphurised and denitrogenated liquid hydrocarbon fuel and recovering the upgraded liquid hydrocarbon fuel.

Process for upgrading of liquid hydrocarbon fuels

The present invention relates to a novel polypouch for packaging of mineral oils. Said polypouch is made up of multilayered polymeric sheet or film of different inventive thicknesses by co-extruded unique combination of low density polyethylene, nylon and adhesive resin resulting in negligible permeation loss of packed mineral oils e.g. kerosene oil.
