Abstract: A geothermal system including a heat-driven process system using heat extracted from a magma wellbore for driving a thermal process. The system includes a magma wellbore connected to the heat-driven process system in a closed loop. A heated heat transfer fluid conveys the heat from the magma wellbore to a reactor housing a decomposition reaction. The reactor can be a batch reactor, a continuous reactor, or a through-flow reactor. The heat provides the reaction temperature necessary for driving the decomposition reaction of a polymer to an end product. The heat can be provided directly by the heated heat transfer fluid, by an intermediate heat transfer fluid heated by the heated heat transfer fluid, or by a reaction medium heated by the heated heat transfer fluid.

Abstract: According to the present invention, organic material is converted to biogas through anaerobic digestion and the biogas is purified to yield a combustible fluid feedstock comprising methane. A fuel production facility utilizes or arranges to utilize combustible fluid feedstock to generate renewable hydrogen that is used to hydrogenate crude oil derived hydrocarbons in a process to make transportation or heating fuel. The renewable hydrogen is combined with crude oil derived hydrocarbons that have been desulfurized under conditions to hydrogenate the liquid hydrocarbon with the renewable hydrogen or alternatively, the renewable hydrogen can be added to a reactor operated so as to simultaneously desulfurize and hydrogenate the hydrocarbons. The present invention enables a party to receive a renewable fuel credit for the transportation or heating fuel.

Abstract: Methods for making higher-octane fuel components from a feed stream of C8+ paraffins, including catalytically cracking the C8+ paraffins using a Zeolite catalyst to produce a reaction product of mid-chain paraffins and olefins and short-chain paraffins and olefins. The reaction product comprises liquid phase paraffins having an increased Octane Value over the feed stream paraffins. The reaction product further comprises a gas phase of short-chain paraffins which are separated from the liquid phase. In embodiments, the short chain olefins are hydrogenated to form mid-chain paraffins and a gas phase containing short-chain paraffins.

Abstract: Systems and methods to provide low carbon intensity (CI) hydrogen through one or more targeted reductions of carbon emissions based upon an analysis of carbon emissions associated with a combination of various options for feedstock procurement, feedstock refining, processing, or transformation, and hydrogen distribution pathways to end users. Such options are selected to maintain the total CI (carbon emissions per unit energy) of the hydrogen below a pre-selected threshold that defines an upper limit of CI for the hydrogen.

Abstract: A method for treating a waste plastic based on a persulfate system is provided. The method includes the following steps: mixing the waste plastic, sulfuric acid, sulfate, peroxymonosulfate, and water, and reacting at 80-140° C. for 3-15 h to complete the treatment; where the waste plastic is polyethylene or polyethylene terephthalate; and the sulfate is copper sulfate or ferrous sulfate. The present invention reasonably regulates and controls each parameter in the reaction process while constructing a homogeneous catalysis system of transition metal activated peroxymonosulfate, and finally directionally converts the waste plastic into C7H12 and C10H12 fuels, which realizes high-efficiency recycling of the waste plastic, has a simple and convenient working procedure, and has a wide application prospect.
