The present disclosure provides methods and apparatus for catalytic cracking of hydrocarbon feed. The apparatus includes a plurality of stages, wherein hydrocarbon feed is introduced into a bottom stage reactor and flows in an overall upward direction. A reaction catalyst stream is introduced into a top stage reactor and flows in an overall downward direction. In each of the stages, the hydrocarbon feed is allowed to come in contact with the reaction catalyst stream received at the particular stage for cracking of the hydrocarbon feed. The final cracked product stream is obtained at an outlet of the top stage reactor and a final spent catalyst stream is obtained at an outlet of the bottom stage reactor.

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.

Method(s) and system(s) for estimation of cold-flow properties of refinery product blends are described. The method may include receiving refinery products to be blended and ratios of the refinery products to be used for producing the refinery product blend, and determining whether the refinery products include at least one heavy product. The cold-flow property of the refinery product blend can be estimated based on a first correlation when the refinery products include the at least one heavy product, and based on a second correlation when the refinery products include no heavy product. The first correlation and the second correlation can differ in at least a sign of a coefficient.

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.
