Abstract
The method relates generally to an improved method of the recovery of hydro-carbons from bitumen/oil deposits such as oil sands, tar sands, oil shales and conventional oil deposits. The method charges the silicon particles thus repulsing the oil, at the same time the hydrogen peroxide selectively reacts with metals, metal compounds and the charged silicon particles giving off energy and oxygen which then floats the oil to the surface. By reacting with the organo-metallic compounds it destroys them thus freeing the oil from transition metals producing a much cleaner product.

4 = ' of I3ydro$en Peroxide Capacitor Process for the Recovery Hydrocarbops -~ =
Field of the Invention This invention relates generally to a method of separating hydrocarbons from another rnatcrial and in ptuticul.ar to a process for recovering hydrocarbons from oil type dGposits, such as bitumenlail sands, oil slaales, and conventional.oil deposits.
Back&round of the Invention = :
The physical separation of oil, bitumen and kerogen, from sand or rock has been an ongoing problem with all the deposits throu ;hout the world. Current methods are usually pyrolysis, hot water arad sodium hydroxide, or dilution with sUlvent.y Such xylene or toluene. All of these processe.s have trouble dealing with the iaeavy fraction of the oil which contains the asphstatenes, as well, the colloids and new compounds formed; make the remediation and cfisposal cxf their tailings very dift7cult and expensive.
Also by the very naturc of ctirtent practices there are exceedingly significant losses in product such that only with extremely high capital investments in order to achieve economies of size or by high crude pi7ces caat the eperations be made econoa .ically vitthle.
At present at Fort McMurray, in the Athabasca tar sands, there are huge inventories of byproducts formed, such as oi1 coke and gypsum (NaSO4), which are too large for the available market. Other onguing problcins are the high use of both water and propatte to the point that the Pmvincial government is considering restrictions on their use.
Summary of the Inventao1~
It is the object of ihe inventio.n to provide an improved process for the separation and extraction of bitumen and oil from the tar sands such tbat there romains little, or no, metals, sand and colloids in the bitunien and very little, or no, hydrocarbons in the sand tailings.
It is altio an objeit of the invention to have a very high throuah-put and yet take up YninirA]b1I space so ~hdt capital costs antl ongoing costs may be sllb:St,1lnllally 1r+oducCd.
It is another object of the invcntion to provide very wmich iniPmved recycling of the water used so Lhat both heat and water may be conserved, ft is another object ofthe invention that a,~ the process is exothermic it will provide heat with the consequent reduction in the use of prnpane or other heating sources.
It is an object of the invetttiom that organo-metals are freed from the hydrocarbon rnatrixe It is an object of the invention that because of the s.implicity of the reaction and reagent used there will be very few, if any, by-products.
The process comprises the following steps_ a) imr,nersing the oil type depacit material in a 54lution comprising of water and hydrogen peroxidi:
b) utilizing two large area electrodes apply a high voltage direct current to the solution until all t}te hydrocarbons have floated to the surface_ Assistance by an agitation source may, at tinzes he required.
c) skimming off the liquid hydrocarbons and placino it in a suitable container d) decnnting the solurion througb a filter and thett precipitating unwanted residues c) storing the solution for further recycling use f} sending the cleanecl sand to a tailings disposal site.

and clean oil/bitamen. The process utilizes a s.olution of'hydrogen peroxide and water hetd between two laa-ge carbon e[ectrodes_ A 100 volt DC current is then applied to the two e]ectrcxies. At this time it will be noted that the ammeter shows a current dvaw of one to two amps. The bitumcn sand can be placed nnywhere in the container between the two electrodes but to facilitate the reaction it is placed on a fine pJastic screen such that as the sand is rclcased ,From the oil it automadcatly falls away from the tar sand and because of entrained gases the liquid hydn,)carhons will then automatically float to the lurfacc.
The process utilizes wide, large area carbon clectrodes and a high voltage in order to cfury a heavy charge on eacli plate creating an electromagnetic field within the cootainer_ The beavily charged plates induce a charge both on the silica particles and within the conductivc nWent water that rernains balanced as long as the water temperature remains be1ow a critical temperQture of seventy degrees Celsius. The sand acts as a diclectrfc separating the two solutions.
The combination of exothermic heat from the oxidation reaction of hydrogen peroxide and meta7s within the ashphaltenes and added "make-up" hcat bring the solution above seventy degrecs Celsius at witich point the silica loses its diarnagrnotism and ability to fiold a ehzurge.
