  • Process of making and using adsorbent to remove heavy metal from waste water
    Patent number: 8211314
    Abstract: The present disclosure describes using the naturally present dissolved chemicals as precipitants from local water sources to form an adsorbent and a process of purifying the water using natural resources. The adsorbent may be processed at the right pH and temperature to purify and remove heavy metals from waste water. Once the heavy metals are removed the concentration of the heavy metals are estimated in the reusable water. The local authority acceptable level heavy metal containing reusable water is reclaimed for non-human consumption. This disclosure enables to conserve water and provide a cheap and an effective method to decontaminate industrial waste water.

  • Separation of methane from higher carbon number hydrocarbons utilizing zeolitic imidazolate framework materials
    Patent number: 8192709
    Abstract: The present invention relates to the selective separation of methane (“CH4”) from higher carbon number hydrocarbons (“HHC”s) in streams containing both methane and higher carbon number hydrocarbons (e.g. ethylene, ethane, propylene, propane, etc.) utilizing a zeolitic imidazolate framework (“ZIF”) material. Preferably, the stream to be separated is fed to the present process in a substantially gaseous phase. In preferred embodiments, the current invention is utilized in a process to separate methane from higher carbon number hydrocarbons in natural gas streams.
