Simulation of petcoke gasification in slagging moving bed reactors

High-pressure co-gasification of coal with biomass and petroleum coke

“…5 The gas yield, Y, was calculated as the outgoing dry gas flow rate per mass flow rate of dry fuel. The gas high heating value, GHHV, was defined as the gross calorific value of dry gas on a volumetric basis.…”

“…[1][2][3][4][5][6].This originates an increase in gas yield and its HHV, which leads to a higher cold gas efficiency. These results agree with the studies published by other authors who employed different types of gasifiers such as pressurized spouted bed and fluidised bed reactors [13,[17][18][19][20].…”

“…), other than coal can be used as feedstock. Petroleum coke is an important byproduct of petroleum refineries, and it is employed as feedstock in gasification systems, in combination with coal or separately, to produce a syngas that can be used to satisfy the increasing demand for hydrogen by refineries, and other applications [5]. Moreover, the cogasification of biomass with coal, could contribute to the reduction of the fossil fuels dependency and CO 2 emissions, as biomass is known to be neutral as regards CO 2 emissions [6].…”

Gasification characteristics of coke and mixture with coal in an entrained-flow gasifier

“…But some gasification processes have used petroleum coke, the byproduct of coking or refinery processes, as the gasification feedstock in combination with coal or separately to produce syngas that can be used to satisfy the increasing demand for hydrogen by refineries and other applications [4]. Especially the disposal of petroleum coke with high sulfur content has arisen as an urgent problem [5], so the gasification processes using petroleum coke have been developed and used.…”

Dynamic modeling and simulation of shell gasifier in IGCC

“…The environmental performance, feedstock flexibility, capital, and operational costs of different gasifiers were compared by Zheng and Furinsky [19] using ASPEN software. Numerical methods were also employed to solve the steady-state temperature and gas composition distributions in the gasifier [20][21][22]. For instance, Vamvuka and Woodbum [23,24] developed a one-dimensional steady-state model for an entrained flow coal gasifier, and predicted the temperature, reaction rate, and composition profiles in a tubular gasifier.…”
