Task 3 -- Bench-scale char upgrading and utilization study

PDF Version Also Available for Download.

Description

This report describes the results of the bench-scale char upgrading study conducted as Task 3 of Development of an Advanced, Continuous Mild Gasification Process for the Production of Coproducts. A process where the char is gasified to produce methane in a first stage reactor was investigated. This methane is then decomposed to produce carbon and hydrogen for recycle in a second stage. The results indicate that both reaction steps are feasible using mild gasification char as the starting feedstock. Conditions for methanation are 700 to 800 C and 200 to 400 psig. Carbon formation conditions are 1,200 to 1,400 C ... continued below

Carbon formation conditions are 1,200 to 1,400 C at atmospheric pressure. The carbon produced has properties similar to those of carbons which are commercially marketed as carbon black.
