In this article, the authors present the scientific and practical aspects of tar formation and conversion during gasification as a function of various technological and technical parameters and variables, and present a review of the most cumbersome and problematic parameter in any gasification commercialization effort.
Abstract
The main purpose of this review is to update the information on gasification tar, the most cumbersome and problematic parameter in any gasification commercialization effort. The work aims to present to the community the scientific and practical aspects of tar formation and conversion (removal) during gasification as a function of the various technological and technical parameters and variables.
