The present invention relates to a system and method for real-time dynamic optimization of crude distillation unit (CDU). The present invention makes use of a combination of CDU and plant data such as crude density, flow, temperature profile and pressure profile of column, other operating conditions, and column heat balance to calculate product yields and product properties. The present invention makes use of real-time CDU or plant measurements, and its non-linear time-dependent functions to represent change in feedstock (product) characteristics, and predict the optimal value of CDU input data to optimize the CDU, and product yields and product properties. This provides a robust optimized solution that significantly reduces the computational time, accounts for dynamic change in crude composition and the unsteady nature of the operation during crude transitions.

A method for modification of pretreated acidic porous material via selective cation exchange using suitable solvent to obtain higher noble metal dispersion is described herein. The solvent system required for cation exchange should have its dielectric constant in the range of 25-45, wherein this solvent property is found to impart significant effect on cation loading and distribution, which in turn defines the stability, dispersion of the noble metals. The catalyst so obtained has higher noble metal dispersion and when used for hydroisomerization reaction, leads to higher selectivity even at significantly high conversion values.

The present invention discloses activated carbon-metal organic framework composite materials (AC@MOF) with enhanced gas adsorption capacity. The present invention also discloses a process for the preparation of carbon-metal organic framework composite materials (AC@MOF). The present invention involves the use of 'void space filling method' in metal organic frameworks (MOFs), which have been accomplished by in-situ addition of selected type and appropriate amount of activated carbon during the synthesis of MOF such as Cu-BTC, in the storage of gases such as methane. The gas adsorption capacity of these AC@MOF composite materials is significantly increased through this method.
