Abstract: The present disclosure relates to a processes and systems for producing fuels from biomass with high carbon conversion efficiency. The processes and systems described herein provide a highly efficient process for producing hydrocarbons from biomass with very low Green House Gas (GHG) emissions using a specific combination of components, process flows, and recycle streams. The processes and systems described herein provide a carbon conversion efficiency greater than 95% with little to no GHG in the flue gas due to the novel arrangement of components and utilizes renewable energy to provide energy to some components. The system reuses water and carbon dioxide produced in the process flows and recycles naphtha and tail gas streams to other units in the system for additional conversion to syngas to produce hydrocarbon-based fuels.

Abstract: A method and a system for drying a biomass, wet pulverized coal or combinations thereof, using heat from a Fischer-Tropsch synthesis in a heat exchanger to heat a nitrogen gas, using a flue gas in a heater to heat the heated nitrogen gas to a higher temperature, passing the twice heated nitrogen gas through apparatus to pulverize the fuel source of coal, biomass or both, forming a gas/particulate stream, filtering the gas/particulate stream in a filter to remove dried fuel feed stocks and using a blower to form a first steam and nitrogen mixture for discharge, and a second steam and nitrogen mixture for mixing with additional dry nitrogen gas for introduction to the first step of the method, at the heat exchanger.

Abstract: A lubricating oil composition for internal combustion engines giving improved soot dispersancy. That lubricating oil composition has a mixture of borated and carbonated polyalkylene succinimides derived from different molecular weight polyalkylenes. The molecular weight of the polyalkylenes from which the carbonated polyalkylene succinimide is derived is at least 300 greater than the molecular weight of the polyalkylenes from which the borated polyalkylene succinimide is derived.
