Supercritical water gasification (SCWG) is a promising waste treatment technology for streams from wine industry, which can eliminate its pollution and produce biofuels simultaneously. In this study, we investigated the influence of catalyst concentration and temperature for efficient SCWG so as to shift the product distribution toward more desirable compounds. Also, experiments have been demonstrated to examine the effect of the group 1A carbonates (Li₂CO₃, Na₂CO₃, K₂CO₃, and Cs₂CO₃). Wine industry wastes have been successfully gasified and the products were identified by using chromatographic methods. As going down from top to bottom in group 1A by increasing reaction temperature, the highest H₂ and CH₄ yields were obtained with Cs₂CO₃ at 600 °C. These results support the development of the reaction conditions by effective catalysts to contribute to the solution of the global bioenergy shortage and effective waste management of the industry.

超临界水气化（SCWG）是一种很有前途的葡萄酒工业废水处理技术，可以消除其污染并同时生产生物燃料。在这项研究中，我们研究了催化剂浓度和温度对高效 SCWG 的影响，以便将产品分布转向更理想的化合物。此外，实验已经证明可以检查 1A 组碳酸盐（Li ₂ CO ₃、Na ₂ CO ₃、K ₂ CO ₃和 Cs ₂ CO ₃）。已成功气化葡萄酒工业废物，并通过色谱方法对产品进行了鉴定。在 1A 组中，随着反应温度的升高，从上到下，在 600°C 下使用 Cs ₂ CO ₃获得最高的 H ₂和 CH ₄产率。这些结果支持通过有效催化剂开发反应条件，为解决全球生物能源短缺和该行业的有效废物管理做出贡献。
