Optimized Process for Melt Pyrolysis of Methane to Produce Hydrogen and Carbon Black over Ni Foam/NaCl-KCl Catalyst

Evaluation of process configurations to produce hydrogen from black liquor

Black liquor is the residue from the kraft paper pulp process and consists, mainly, of water, lignin, organic residues from cellulose and hemicelluloses and inorganic matter (mostly sodium, potassium and sulfur). Before any combustion or gasification, the dry content of the black liquor is increased, typically from 14-18% to 75-80%, to permit autogenous combustion and high conversion efficiency...

CO x Free Hydrogen Production by Catalytic Decomposition of Methane Over Porous Ni/Al2O3 Catalysts

pyrolysis of date palm trunks to produce active carbon

active carbon is char derived from pyrolysis of organic materials. it has a high porosity level and is used to filter fluids. many types of agricultural materials are used to produce active carbon. the trunk of the date palm, with its low density and high porosity, has great potential for producing active carbon. in this research, the bark was pyrolyzed at 450°c for 60 min to produce active car...

Preparation of Carbon Molecular Sieves from Pistachio Shell and Walnut Shell for Kinetic Separation of Carbon Monoxide, Hydrogen, and Methane

In this study, two Carbon Molecular Sieves using Pistachio shell (CMS P) and Walnut shell (CMS W) were prepared by a chemical vapor deposition method and used for pressure swing adsorption and separation of CO/H2 and CO/CH4. Adsorption isotherms of gases obtained for both CMS’s. The Dubinin-Radushkevich isotherm model was used for comparing pore volum...

Pseudomorphic Reaction: A New Approach to Produce Bulk Mesoporous Silica as Catalyst Support in Methane Reforming

Pseudomorphism is known as a suitable technique for producing mesoscale pore in silica powders keeping their original morphologies. Herein, silica discs with several millimeter dimensions have been prepared using the same method. This method has been utilized through application of pseudomorphism reaction of preshaped bodies by immersion in a solution containing surfactant and swelling re...
