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 ofstrain IOCX,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 ofstrain IOC5al,strain IOCRl,and a mixture thereof to degrade the released hydrocarbon.

Method for bio-assisted treatment of hydrocarbon contaminated soil

The present invention relates to a process for the conversion of hydrocarbon streams with 95% true boiling point less than 400&#xb0; 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&#xb0; C., pressure range of 2 to 20 kg/cm(g) and weight hourly space velocity in range of 0.1 to 20 hour, 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.

Process for conversion of hydrocarbons to saturated LPG and high octane gasoline

A process for converting undesirable olefinic hydrocarbon streams to hydrogen and petrochemical feedstock e.g. light olefins in C.sub.2 -C.sub.4 range and aromatics especially toluene and xylenes, which comprises simultaneous cracking and reforming at olefin rich hydrocarbons using a catalyst consisting of dehydrogenating metal components, shape selective zeolite components and large pore acidic components in different proportions in a circulating fluidized bed reactor-regenerator system having reactor temperature within 450-750.degree. C. and WHSV of 0.1-60 hour.sup.-1.

Upgradation of undesirable olefinic liquid hydrocarbon streams

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.
