Introduction to Dry-Feeding Coal Gasification

ability to gasify almost every type of coal in the world, 

high T gasification to increase the coal conversion and to prevent the formation of tar oil and phenol type of organic by-products, 

high syngas productivity from a single gasifier. 

Shell built a 6t/day lab/pilot-scale gasifier to test different types of coal in 1976. It also conducted tests to collect the fundamental data on cleanup of the syngas produced by this gasifier and to assess the technologies to meet environmental regulations. 

At the same time, Shell also built a 150t/day pilot-scale gasifier in one of Shell s refineries at Hamburg, Germany, in 1978. The major task of this pilot plant was to validate the model developed in the Amsterdam lab.
