Capturing, utilizing, and storing CO2 is recognized as a vital strategy to combat climate change driven by fossil fuel use. This approach helps reduce greenhouse gas emissions and promotes sustainability by managing CO2 emissions through innovative capture technologies, exploring its conversion into valuable products, and ensuring safe storage to prevent atmospheric re-entry. Several strategies for CO2 capture have been developed, including pre-combustion, post-combustion, and oxyfuel combustion. Pre-combustion methods can be further categorized into chemical looping, gas-liquid absorption, autothermal reforming, and steam methane reforming. Post-combustion capture is divided into techniques such as absorption, adsorption, membrane separation, cryogenic distillation, calcium looping, and direct air capture. Each of these approaches plays a critical role in reducing CO2 emissions and addressing climate change. This study aims to enhance CO2 capture technologies by providing a comprehensive overview of the current state of carbon capture methods. To achieve this, the major strategies and technologies for capturing CO2 from coal gasification processes have been thoroughly reviewed. The review article is structured into three main sections, covering pre-combustion, post-combustion, and oxyfuel combustion techniques. Each of these methods is further divided into various sub-techniques. The article thoroughly examines the impact of these carbon capture methods, comparing them with other available techniques. It provides readers with a clear understanding of the current status of carbon capture technologies and their effectiveness.

对不同碳捕获技术的深入批判性审查：评估它们在减少气候变化排放方面的有效性和作用


捕获、利用和储存 CO2 被认为是应对化石燃料使用驱动的气候变化的重要策略。这种方法通过创新的捕获技术管理二氧化碳排放，探索将其转化为有价值的产品，并确保安全储存以防止再次进入大气层，从而帮助减少温室气体排放并促进可持续发展。已经开发了几种 CO2 捕获策略，包括预燃烧、后燃烧和火焰燃烧。预燃烧方法可以进一步分为化学循环、气液吸收、自热重整和蒸汽甲烷重整。燃烧后捕集分为吸收、吸附、膜分离、低温蒸馏、钙循环和直接空气捕集等技术。这些方法中的每一种在减少 CO2 排放和应对气候变化方面都发挥着关键作用。本研究旨在通过全面概述碳捕获方法的现状来增强 CO2 捕获技术。为了实现这一目标，已经彻底审查了从煤气化过程中捕获 CO2 的主要策略和技术。综述文章分为三个主要部分，涵盖燃烧前、燃烧后和火焰燃烧技术。这些方法中的每一种都进一步分为各种子技术。本文彻底研究了这些碳捕获方法的影响，并将它们与其他可用技术进行了比较。它让读者清楚地了解碳捕获技术的现状及其有效性。
