This review provides the recent advances in triglyceride catalytic pyrolysis using heterogeneous dolomite catalysts for upgrading biofuel quality. The production of high-quality renewable biofuels through catalytic cracking pyrolysis has gained significant attention due to their high hydrocarbon and volatile matter content. Unlike conventional applications that require high operational costs, long process times, hazardous material pollution, and enormous energy demand, catalytic cracking pyrolysis has overcome these challenges. The use of CaO, MgO, and activated dolomite catalysts has greatly improved the yield and quality of biofuel, reducing the acid value of bio-oil. Modifications of the activated dolomite surface through bifunctional acid-base properties also positively influenced bio-oil production and quality. Dolomite catalysts have been found to be effective in catalyzing the pyrolysis of triglycerides, which are a major component of vegetable oils and animal fats, to produce biofuels. Recent advances in the field include the use of modified dolomite catalysts to improve the activity and selectivity of the catalytic pyrolysis process. Moreover, there is also research enhancement of the synthesis and modification of dolomite catalysts in improving the performance of biofuel yield conversion. Interestingly, this synergy contribution has significantly improved the physicochemical properties of the catalysts such as the structure, surface area, porosity, stability, and bifunctional acid-base properties, which contribute to the catalytic reaction's performance.
本综述介绍了使用非均相白云石催化剂进行甘油三酯催化热解以提升生物燃料质量方面的最新进展。通过催化裂化热解生产高质量可再生生物燃料因其高碳氢化合物和挥发性物质含量而备受关注。与传统应用相比，催化裂化热解克服了传统应用运营成本高、工艺时间长、有害物质污染以及能源需求巨大等问题。氧化钙、氧化镁和活性白云石催化剂的使用极大地提高了生物燃料的产率和质量，降低了生物油的酸值。通过双功能酸碱性质对活性白云石表面进行改性也对生物油的生产和质量产生了积极影响。已发现白云石催化剂能有效催化甘油三酯（植物油和动物脂肪的主要成分）的热解以生产生物燃料。该领域的最新进展包括使用改性白云石催化剂来提高催化热解过程的活性和选择性。此外，在提高生物燃料产率转化性能方面，对白云石催化剂的合成和改性研究也有所加强。有趣的是，这种协同作用显著改善了催化剂的物理化学性质，如结构、表面积、孔隙率、稳定性和双功能酸碱性质，这些性质有助于催化反应的性能。
