However gasification is very energy - intensive , requiring high-temperature air , steam or oxygen to react with the organic material .
然而气化过程的能耗是非常高的,需要高温空气、蒸汽或氧气与有机物质进行反应。
A few dozen gasification and pyrolysis plants are up and running in europe and japan , and more are planned .
欧洲和日本,建起了几十个垃圾气化热解厂,并已投入运作,他们计划建造更多。
Purifying oxygen and raising steam , however , both consume energy . And gasification also requires bespoke plants .
但是提纯氧气和制备水蒸气都需要消耗能源,气化还需要在预定的工厂内进行。
Two other techniques , called gasification and oxy-combustion , work by reacting coal with pure oxygen rather than air , and thus produce exhausts that require little treatment before burial .
其他两种叫做气化和富氧燃烧的技术,用纯氧气而不是空气烧煤,这样产生的废气在掩埋之前几乎不用处理。
Scientists have adapted a process called " gasification " which is already used to clean up dirty materials before they are used to generate electricity or to make renewable fuels .
We intend to increase supplies of natural gas , the cleanest-burning fossil fuel , we offer coal and biomass gasification technology and we 're a sizable player in wind .
Shell possesses coal gasification technology which can also be used for gasifying biomass , including wood pellets .
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。
Castaldi 's process reduces the amount of water that needs to be heated in the gasifier , thereby saving energy , and is 10 to 30 % more efficient than standard gasification .
Although it can be used to make fertiliser through a process of gasification , manufacturers find natural gas to be a cheaper alternative .
尽管也可以通过气化无烟煤来制造化肥,但化肥制造商认为天然气是更廉价的选择。
His team calculated that using co 2 during gasification of a biomass fuel such as beechgrass , in order to make enough biofuel for a fifth of the world 's transport demands , would use up 437m tonnes of the greenhouse gas .
