AM-02-10 A NEW CONTINUOUS CATALYTIC PROCESS FOR DESULFURIZATION OF SYNGAS AND HYDROCARBONS

Description:

Gasification has become a mature technology for conversion of carbonaceous fuels into a COand H2-rich syngas for hydrogen production, chemical processing, or electric power generation. There are now approximately 160 gasification plants worldwide, which use a variety of feedstocks. The use of petroleum-derived feedstocks, such as resid or petroleum coke, is growing as more refineries take advantage of gasification as a method of processing low value and waste materials and generating syngas for production of value-added chemicals, hydrogen, steam, and/or electric power. During the last decade, petroleum derived feedstocks represented approximately 40 percent of all gasifier feeds. Similar to coal, the petroleum-based feedstocks produce syngas contaminated with H2S and COS. For example, petroleum coke can typically generate syngas containing up to 2 vol% H2S and COS. As the interest in gasification increases, a greater need for desulfurization technology is generated
