Several organic wastes into energy conversion technologies were successful in addressing global challenges such as fossil fuel dependency, production cost optimization, waste management and emission control issues. The utilization of organic wastes for biofuels production is considered as a plausible approach for achieving better energy security, pollution control, process economics, sustainable production,...
Numerical bifurcation analysis of delayed recycle stream in a continuous stirred tank reactor was studied using DDE-BIFTOOL. A first-order irreversible exothermic reaction s1→k2,1s2 was considered for analyzing effect of delay on the stability of the delayed recycle system. The non-isothermal CSTR was operated at both infinite and finite coolant inlet flowrates. A constant delay was considered in...
A flow graph theory is a method for finding the analytical solution of linear differential equations which arise in chemical kinetics through Cramer's method of determinants. This article presents the applicability of flow graph theory for deriving the analytical solution of kinetic equations which arise in modeling of complex reaction system such as hydrocracking of heavy oils. A discrete lumped...
This article presents a comprehensive kinetic model for thermal cracking of waste cooking oil using monomolecular lumped kinetics. The chemical lumps were classified on the basis of carbon number range of the hydrocarbons and a first order irreversible monomolecular cracking kinetics was considered for finding the product concentration in a reactor. Arrhenius kinetic law was applied for determining...
A discrete lumped kinetic model for thermal cracking of Kuwaiti vacuum residues such as Ratawi–Burgan vacuum residue (RB-VR), Lower-Fars vacuum residue (LF-VR) and Eocene vacuum residue (EC-VR) in the Eureka process is presented. The discrete lumps considered for kinetic modeling of thermal cracking reactions are: (i) off-gases (<423K), (ii) cracked light oil (423–643K), (iii) cracked heavy oil...
