Treatment of opium alkaloid wastewater is not sufficient using the existing combined methods of aerobic/anaerobic and chemical treatment. Hydrothermal gasification (HTG) is proposed as an alternative treatment in this study. The other aim of this study is to show the ability to manufacture CH<span style="font-size: 12.75px; line-height: 0; position: relative; vertical-align: initial; bottom: -0.25em;">4</span> and H<span style="font-size: 12.75px; line-height: 0; position: relative; vertical-align: initial; bottom: -0.25em;">2</span> as renewable energy sources and to determine to what extent the removal of chemical oxygen demand (<em class="EmphasisTypeItalic ">COD</em>) is. Studies were carried out in batch autoclave reactor systems without catalyst, with original red mud (RM), activated RM, and nickel-impregnated (10, 20, and 30%) forms. Reduction with NaBH<span style="font-size: 12.75px; line-height: 0; position: relative; vertical-align: initial; bottom: -0.25em;">4</span> was done to the nickel-impregnated forms of RM to increase the catalytic activity. Yields of CH<span style="font-size: 12.75px; line-height: 0; position: relative; vertical-align: initial; bottom: -0.25em;">4</span> and H<span style="font-size: 12.75px; line-height: 0; position: relative; vertical-align: initial; bottom: -0.25em;">2</span> increased from 16.8 to 28.6 mol CH<span style="font-size: 12.75px; line-height: 0; position: relative; vertical-align: initial; bottom: -0.25em;">4</span>/kg C in wastewater and from 20.3 to 33.3 mol H<span style="font-size: 12.75px; line-height: 0; position: relative; vertical-align: initial; bottom: -0.25em;">2</span>/kg C in wastewater with 20% impregnated nickel and reduced red mud as the highest at 500 °C. The <em class="EmphasisTypeItalic ">COD</em> of the wastewater was lowered by 81–85% approximately while the <em class="EmphasisTypeItalic ">TOC</em> content decreased by 85–90%.</p></section><div class="KeywordGroup" lang="en" style="margin-bottom: 24px; color: rgb(51, 51, 51); font-family: Georgia, serif; font-size: 17px; letter-spacing: 0.102px; background-color: rgb(252, 252, 252);"><h2 class="Heading" style="line-height: 1.3; font-size: 2.6rem; color: rgb(51, 51, 51); letter-spacing: 0.008em; margin-top: 0.5em; margin-bottom: 0.5em; font-family: Georgia, serif;">Keywords</h2><h2 class="Heading" style="line-height: 1.3; font-size: 2.6rem; color: rgb(51, 51, 51); letter-spacing: 0.008em; margin-top: 0.5em; margin-bottom: 0.5em;"><span class="Keyword" style="display: inline-block; background-color: rgb(242, 242, 242); border-radius: 2px; margin-bottom: 0.3em; margin-right: 0.3em; padding: 0px 0.2em; font-size: 17px; letter-spacing: 0.102px;">Biomass </span><span class="Keyword" style="display: inline-block; background-color: rgb(242, 242, 242); border-radius: 2px; margin-bottom: 0.3em; margin-right: 0.3em; padding: 0px 0.2em; font-size: 17px; letter-spacing: 0.102px;">Wastewater </span><span class="Keyword" style="display: inline-block; background-color: rgb(242, 242, 242); border-radius: 2px; margin-bottom: 0.3em; margin-right: 0.3em; padding: 0px 0.2em; font-size: 17px; letter-spacing: 0.102px;">Supercritical </span><span class="Keyword" style="display: inline-block; background-color: rgb(242, 242, 242); border-radius: 2px; margin-bottom: 0.3em; margin-right: 0.3em; padding: 0px 0.2em; font-size: 17px; letter-spacing: 0.102px;">Gasification </span><span class="Keyword" style="display: inline-block; background-color: rgb(242, 242, 242); border-radius: 2px; margin-bottom: 0.3em; margin-right: 0.3em; padding: 0px 0.2em; font-size: 17px; letter-spacing: 0.102px;">Hydrogen </span><br></h2></div>
