  • Patent number: 8927797
    Abstract: The method produces a hydrocarbonaceous fluid (a liquid mixture of hydrocarbons, or in other words a mixture of hydrocarbons which is liquid at ambient room temperature and atmospheric pressure), which functionally is a liquid hydrocarbon fuel, from a feed of waste plastic. The method can comprise the steps of: (step 1) melting a feed of substantially solid waste plastic in an aerobic atmosphere (for instance, air) whereby a waste-plastic melt is produced; (step 2) distilling at least a portion of the waste-plastic melt whereby a hydrocarbonaceous distillate is produced; and (step 3) collecting the hydrocarbonaceous distillate. That distillate is generally referred to above as a condensate. The method can include the step of comminuting the feed of substantially solid waste plastic into pieces substantially no greater than about 1.5 cm2 prior to step 1. The method can also include the step of adding an effective amount of a cracking catalyst to the waste plastic prior to step 2.

  • Patent number: 8920609
    Abstract: The device and method are provided to increase anhydrosugars yield during pyrolysis of biomass. This increase is achieved by injection of a liquid or gas into the vapor stream of any pyrolysis reactor prior to the reactor condensers. A second feature of our technology is the utilization of sonication, microwave excitation, or shear mixing of the biomass to increase the acid catalyst rate for demineralization or removal of hemicellulose prior to pyrolysis. The increased reactivity of these treatments reduces reaction time as well as the required amount of catalyst to less than half of that otherwise required. A fractional condensation system employed by our pyrolysis reactor is another feature of our technology. This system condenses bio-oil pyrolysis vapors to various desired fractions by differential temperature manipulation of individual condensers comprising a condenser chain.

    Abstract: Biomass is used as a co-feed for a heavy petroleum oil coking process to improve the operation of the coking process and to utilize biomaterial for the production of transportation fuels. The coking process may be a delayed coking process or a fluidized bed coking process and in each case, the presence of the biomass will decrease the coke drying time so reducing coke handling problems in the unit besides forming a superior coke product. In the case of a fluidized bed coking process using a gasifier for the coke, the addition of an alkali metal salt improves the operation of the gasifier.

  • Patent number: 4511459
    Abstract: Coking of residual oil and devolatization/partial gasification and desulfurization of solid particulate fuel are carried out in a single reactor. The particulate fuel is burned in a combustion zone in the bottom of the reactor. A bed of particulate fuel is fluidized above the combustion zone with gases rising from the combustion zone. The fluidized bed is maintained at a temperature which cokes the residual oil and volatizes the particulate fuel. A high temperature, low velocity zone is maintained between the combustion zone and the fluidized bed for calcination and desulfurization of the solid fuel.

  • Patent number: 4421604
    Abstract: The quality of coke is improved by measuring the width of a plastic zone of a given type of coal, comparing said measured zone with a predetermined zone width known to result in good quality coke, adjusting certain characteristics of said given coal prior to charging it into the coke oven to cause a change in said zone width of the coal that will ultimately result in improved coke quality. Typical adjusting steps include preheating the coal and/or the addition of coal binders, such as, various carbon and petro-based binding agents, for example, pitch.

  • Patent number: 4396396
    Abstract: A method of deashing coal wherein the coal is wetted with hydrocarbon liquid to form agglomerates and the hydrophilic agglomerates are then separated from a water and ash phase to yield deashed coal agglomerates. The hydrocarbon liquid is then recovered from the coal agglomerates by a vacuum stripping in the absence of oxidizing gases with or without use of super heated steam. Where super heated steam is used the removed hydrocarbon liquid is subsequently separated from the steam by cooling.
