MODELING STUDIES ON PRODUCTION OF HYDROGEN FROM DRY REFORMING

Abstract

Hydmgcn is clean energy carrier and forecast to become a major energy source in futon. Produetiou of hydrogen from methane, naphtha, heavy oil and coal bas achieved increased importance in recent years. This is because of the incena. d demand for hydrogen, both for petroleum refining pro sans such as hydrotreating and hydeocrecking and for the petroehcm ccat use in the producoou of medrannl, methanol to gasoline (MTG), ammonia and hydrocarbon synthesis via FischeaTropsch (F T)processes. ha the feoaen[ study, a one dimensional ieuthermal model permeable membrane enactor has been developed to simulate the dry reforming of methane to produce hydmgeo. The performance of one coed bed reactors (Ff1R) with argon in feed and two membrane reactors re. Vycor glass membrane reactor (MRt) sod Ceramic membrane (MR2) having argon m shell and tube side have heed studied of various feed conditions and temperatures in order m inv sfigam the effect of these par meters on conversion of methane. loss of hydrogen, s,lccttccty of hydrogen and yield of hydrogen The MR2 feed has been toned to provide better perfonneocc as compared to fixd bed enactor MRI-The model equations have hone solved for mentioned operating and boundory conditions by using ODE solver in MATLAB R20075
