壳牌拥有的煤气化技术也可用于包括木屑颗粒在内的生物质气化。

Gasifying coal to produce chemicals emits less carbon dioxide than does burning coal as fuel , but the process still ejects more carbon dioxide into the atmosphere than using natural gas would produce , says eric larson , a research engineer at the princeton environmental institute .

普林斯顿环境研究院（princetonenvironmentalinstitute）的研究工程师埃里克拉森（ericlarson）说，采用煤炭气化技术生产化工产品比直接燃烧煤炭所产生的二氧化碳要少，但仍比燃烧天然气产生的二氧化碳要多。
