[ 1 ] - Modeling and Simulation of Alternative Injections of CO2 and Water into Porous Carbonate Formations
Water alternating gas (WAG) technique is used in the petroleum industry to inject carbon dioxide (CO2) into underground formations either for sequestration or enhanced oil recovery (EOR) processes. CO2 injection causes reactions with formation brine or aquifer and produces carbonic acid, the acid dissolves calcite and changes flow behavior significantly. Modeling and investigating effects of CO...
[ 2 ] - Modeling of platinum leaching kinetics in aqua-regia solutions using the Elovich equation
Platinum extraction from different secondary sources has been experimentally tested by many researchers. In this article, dissolution of platinum in aqua-regia solution from two types of spent catalysts (reforming and nitric acid production) was kinetically studied. A variety of kinetic models for heterogeneous solid-liquid reactions, including homogeneous diffusion model, shrinking core model,...
[ 3 ] - سنتز زئولیت ZSM-5 به عنوان کاتالیست فرایند تبدیل متانول به پروپیلن
در این پژوهش، کاتالیست زئولیتی ZSM-5 با نسبت بالای سیلیسیوم به آلومینیم برابر 800 برای فرایند تبدیل متانول به پروپیلن (MTP) سنتز شده است. در سنتز این کاتالیست از قالب آلی تترا پروپیل آمونیوم برمید استفاده شده است که نسبت به تترا پروپیل آمونیوم هیدروکسید که به طور معمول به عنوان قالب آلی استفاده می شود به مراتب ارزان تر است. آزمون راکتو...
[ 4 ] - Platinum Extraction Modeling from Used Catalyst by Iodine Solutions
Platinum extraction from spent reforming catalysts in iodine solutions under atmospheric pressure at different temperatures, acid concentration, and iodine spices concentration, catalyst particle size, and impeller agitation speed have been studied in our group. In this system, platinum is oxidized from spent catalyst with I3¯ that is formed ...
