摘要:
Provided is a method of treating a hydrocarbon-contaminated soil/gravel with a blend of microbes by adding a first microbe selected from the group consisting of Pseudomonas aeruginosa strain IOCX, Pseudomonas aeruginosa strain IOC DHT and mixtures thereof to a hydrocarbon-contaminated soil/gravel to release the hydrocarbon; and adding a second microbe selected from the group consisting of Pseudomonas putida strain IOC5al, Pseudomonas putida strain IOCRl, Bacillus subtlis and a mixture thereof to degrade the released hydrocarbon.

摘要:
The present invention relates to a process for the conversion of hydrocarbon streams with 95% true boiling point less than 400° C. to very high yield of liquefied petroleum gas in the range of 45-65 wt % of feed and high octane gasoline, the said process comprises catalytic cracking of the hydrocarbons using a solid fluidizable catalyst comprising a medium pore crystalline alumino-silicates with or without Y-zeolite, non crystalline acidic materials or combinations thereof in a fluidized dense bed reactor operating at a temperature range of 400 to 550° C., pressure range of 2 to 20 kg/cm2 (g) and weight hourly space velocity in range of 0.1 to 20 hour−1, wherein the said dense bed reactor is in flow communication to a catalyst stripper and a regenerator for continuous regeneration of the coked catalyst in presence of air and or oxygen containing gases, the catalyst being continuously circulated between the reactor-regenerator system.
摘要:
Disclosed herein is a bio-assisted method for treatment of hydrocarbon contaminated soil employing novel microbes which are capable of decontaminating hydrocarbon contaminated soil having free flowing water or in slurry form or having large amount of gravels. The method comprises adding hydrocarbon releasing microbes followed by adding the microbes capable of degrading the released hydrocarbon to decontaminate the soil, wherein said microbes are grown separately in suitable vessels containing a suitable nutrient medium.
摘要:
A process for preparing benzene containing less than 1 ppm (wt) dioxane from an aromatic stream containing benzene which is contaminated with dioxane, the process including providing an aromatic stream containing benzene which is contaminated with dioxane; subjecting the aromatic stream to liquid phase adsorption by contacting an adsorbent contained in at least one column, which adsorbent comprises at least one substance selected from the group consisting of molecular sieves and clay; and recovering benzene containing less than 1 ppm (wt) dioxane. Preferably, the liquid phase adsorption is carried out at a pressure ranging from atmospheric pressure to 20 kg/cm.sup.2 and at a temperature ranging from ambient temperature to 50.degree. C. Preferably, the molecular sieves have a pore size of 10 .ANG.. The process may further include regenerating the adsorbent by passing a flow of nitrogen gas through the adsorbent at a temperature ranging from 200 to 300.degree. C. Alternatively, the process may further include regenerating the adsorbent by heating the adsorbent at a temperature ranging from 200 to 300.degree. C. for a period of time which is effective to regenerate the adsorbent.
