Soil contamination by petroleum hydrocarbon (PHC) is a major concern facing the oil and gas industry. Particularly Condensate liquids have been found to contaminate soil at gas production site. The remediation of PHCs is a difficult challenge due to the complex interaction between contaminant and soil. A study has been conducted to enhance degradation of PHCs by Fenton oxidation and using Nanoscale Zero–Valent Iron as catalyst. The various operating condition such as initial H2O2 concentration, nZVI dosage, reaction time and initial contamination dose were investigated. Central composite design was employed to optimize and analyze the effect of operational parameters on the PHC removal efficiency. It was found that optimal molar ratio of H2O2\Fe0 was 58 with maximum TPH removal of 84% and 3hr reaction time and initial contaminant concentration was 15g oil \kg soil. Based on the results combination of Nanoscale ZVI and Fenton has proved to be a promising remedy for contaminated soil.<\div>

In this work, a simulation of a fixed bed reactor for water gas shift reaction, which forms part of a hydrogen production, was carried out. A commercial CuO\ZnO\Al2O3 catalyst was employed and a one–dimensional heterogeneous model was applied for the simulation. The kinetic information has been taken from literature for the above reaction. The distribution of concentration in fluid bulk as well as porous catalyst, rate of reaction, pressure profile and superficial velocity distribution were represented as results of study. gPROMS, a general purpose modeling package, was used for modeling and simulation of the water–gas shift reaction.<\div>
