Patent number: 11948079Abstract: The present disclosure discloses a multi-agent coordination method. The method includes: performing multiple data collections on N agents to collect E sets of data, where N and E are integers greater than 1; and optimizing neural networks of the N agents using reinforcement learning based on the E sets of data. Each data collection includes: randomly selecting a first coordination pattern from multiple predetermined coordination patterns; obtaining N observations after the N agents act on an environment in the first coordination pattern; determining a first probability and a second probability that a current coordination pattern is the first coordination pattern based on the N observations; and determining a pseudo reward based on the first probability and the second probability. The E sets of data include: a first coordination pattern label indicating the first coordination pattern, the N observations, and the pseudo reward.Type: GrantFiled: October 19, 2020Date of Patent: April 2, 2024Inventors: Xiangyang Ji, Shuncheng He

Patent number: 9611437Abstract: The present disclosure relates generally to a method for obtaining synthesis gas from a gasifier that has a low methane content. The synthesis gas is obtained as an extraction gas from the quench section of the gasifier, and can be utilized as feedstock for a variety of chemical production processes without the need for expensive pre-treatment to remove methane.Type: GrantFiled: January 5, 2011Date of Patent: April 4, 2017Assignee: Lummus Technology Inc.Inventors: Shuncheng Ji, Chancelor L. Williams, Ron W. Herbanek

Patent number: 9175847Abstract: A dry feed two stage gasification system and process is disclosed for gasifying feedstock such as carbonaceous materials with improved energy efficiency, along with reductions in feedstock consumption and carbon dioxide emissions. The feedstock is first dried and pretreated with the hot syngas in the upper section of the gasifier to generate a dry char that is low in volatile-matter content. This dry char is sent to the first stage of a two stage gasifier where it reacts with oxygen in the presence of steam to produce a hot syngas stream.Type: GrantFiled: December 13, 2012Date of Patent: November 3, 2015Assignee: Lummus Technology Inc.Inventor: Shuncheng Ji

Patent number: 8309617Abstract: A process for improving the overall carbon conversion efficiency of a gasification process, as well as improving the suitability of a syngas containing 0.5-10% methane for use as a feedstock for chemical production. A gasification reactor converts carbonaceous feedstock to syngas that is, in turn, utilized for a chemical production process in a chemical production reactor. An off-gas from this chemical production reactor is directed to a selective membrane that separates the off-gas into methane-rich and hydrogen-rich fractions. The hydrogen-rich fraction, is re-utilized as feedstock for the chemical production process, while the methane-enriched fraction is returned to the gasification reactor to form additional syngas.Type: GrantFiled: May 21, 2010Date of Patent: November 13, 2012Assignee: Phillips 66 CompanyInventor: Shuncheng Ji

Patent number: 7172686Abstract: Methods of separating components of a mixture, such as crude oil, are disclosed which increase the yield of individual components while decreasing the yield of residue. In one method, a heated mixture is fed to a column, a vapor stream is withdrawn from the column and separated, and a portion of the vapor stream is recycled back to the column. In another method, a mixture is separated into streams composed substantially of components having light, intermediate or heavy molecular weight and/or low, intermediate or high boiling point, respectively, and the streams are fed into the column at different positions. In both methods, individual light, intermediate and/or heavy molecular weight and/or low, intermediate and/or high boiling point component streams are then selectively withdrawn from the column.Type: GrantFiled: March 12, 2003Date of Patent: February 6, 2007Assignee: The Board of Regents of the University of OklahomaInventors: Shuncheng Ji, Miguel J.
