pyrolysis 指在无氧或缺氧条件下,通过高温加热使有机物质发生化学分解的过程,常用于化工和能源领域。

用法要点

句型搭配

pyrolysis 通常用作名词,在句子中作主语或宾语,描述热解过程或技术。常见于被动语态或与动词如 undergo、involve 搭配。

• The pyrolysis of plastic waste produces fuel.
• Biomass undergoes pyrolysis to create biochar.

介词用法

pyrolysis 常与介词 of 连用,表示被热解的物质,如 pyrolysis of wood;也可用 in 表示在热解过程中,如 in pyrolysis。

• Pyrolysis of tires yields oil and gas.
• Temperatures in pyrolysis can exceed 500°C.

语域说明

pyrolysis 是专业术语,主要用于科学、工程、环境等学术或技术语境,日常对话中较少使用,可替换为更通俗的表达如 thermal decomposition。

• The research focuses on pyrolysis efficiency.
• Industrial pyrolysis plants handle large volumes.

基础例句

In science class, we learned that pyrolysis can turn old plastics into useful fuels.

在科学课上,我们了解到热解可以将旧塑料转化为有用的燃料。

The factory uses pyrolysis to safely dispose of medical waste without burning it.

这家工厂使用热解技术安全处理医疗废物,而无需焚烧。

My friend works on a project that involves pyrolysis of agricultural leftovers to make energy.

我的朋友参与了一个项目,涉及将农业废弃物热解以生产能源。

高级例句

The study investigates the kinetics of biomass pyrolysis under varying pressure conditions to optimize bio-oil yield.

这项研究探讨了在不同压力条件下生物质热解的动力学,以优化生物油的产量。

In the chemical industry, catalytic pyrolysis is employed to enhance the selectivity of hydrocarbon production from waste plastics.

在化学工业中,催化热解被用来提高从废塑料生产碳氢化合物的选择性。

The company's new pyrolysis technology reduces carbon emissions by converting municipal solid waste into syngas for power generation.

该公司的新热解技术通过将城市固体废物转化为合成气用于发电,从而减少碳排放。

常见错误

❌ 错误:The pyrolysis is a burning process.
✓ 正确:Pyrolysis is a thermal decomposition process without combustion.

错误在于将 pyrolysis 等同于燃烧。实际上,pyrolysis 是在无氧或缺氧条件下的热分解,不涉及燃烧;应强调其非燃烧特性以避免误解。

❌ 错误:We do pyrolysis to the plastic.
✓ 正确:We perform pyrolysis on the plastic.

错误在于使用了不地道的介词搭配。在英语中,perform pyrolysis on something 或 subject something to pyrolysis 更常见;应避免直译中文的“对...做热解”。

近义词辨析

thermal decomposition

thermal decomposition 是更广义的术语,指任何通过加热引起的分解,可能包括有氧条件;而 pyrolysis 特指在无氧或缺氧条件下的热分解,常用于专业语境。

Pyrolysis of wood produces charcoal, whereas thermal decomposition might refer to burning in air.

cracking

cracking 通常指在石油化工中,将大分子烃类裂解成小分子的过程,常涉及催化剂;pyrolysis 更通用,可用于各种有机物质,且不一定需要催化剂。

Fluid catalytic cracking is used in refineries, while pyrolysis can be applied to biomass or plastics.
