The production of petroleum coke (petcoke) in the refineries is progressively peaking up
because of the trend of processing heavy crudes and in turn, a renewed interest in delayed …

This paper presents modeling of a coal gasification reaction, and prediction of gasification
performance for an entrained flow coal gasifier. The purposes of this study are to develop an …

Computational Fluid Dynamics (CFD) simulation of commercial-scale two-stage upflow and
single-stage downflow entrained-flow gasifiers was conducted to study effects of simulating …

A comprehensive model for entrained flow coal gasifiers was developed. In addition to the
numerical methods and sub-models conventionally used in the modeling of pulverized coal …

The comprehensive entrained flow coal gasification model developed in Part I was used for
parametric studies to provide a better understanding of two-stage air blown entrained flow …

A central composite design of experiments was performed to optimize a free-fall reactor for
the production of bio-oil from red oak biomass. The effects of four experimental variables …

Gasification of a char has so far been mainly studied at low temperatures and low heating
rates with a TGA (thermogravimetric analyzer). Studies on gasification of a char in CO2 at …

The gasification of a char has, so far, been mainly studied at low temperatures and low
heating rates, using thermogravimetric analysis. Studies on the gasification of a char in CO2 …

CFD (RANS based) simulations of REGA-1 experimental campaign concerning gasification
of glycol in an oxygen-nitrogen mixture have been carried out. The reacting flow-field has …

In a unique fluidized-bed reactor, the gasification reactivity with steam of chars derived
under various conditions was investigated at elevated temperatures. It was revealed that …
