Patent number: 5104516Abstract: Several procedures are provided herein which reduce the viscosity and density of heavy oils to make them amenable for transportation by pipeline from the field to refineries for further processing. The procedure involves contacting a water emulsion of a heavy oil with carbon monoxide at a pressure range and a temperature range such that a water gas shift reaction takes place to convert the steam and carbon monoxide to hydrogen and carbon dioxide. Simultaneously, a thermal rearrangement takes place, thereby reducing the viscosity and density of the oil without any significant thermal cracking. Under one scheme, at a low temperature range, e.g. below about 400.degree. C., there is substantailly no cracking and minimal molecular changes. Under another scheme, at a higher temperature range, e.g. up to about 460.degree. C., significant cracking and molecular changes take place.Type: GrantFiled: September 6, 1990Date of Patent: April 14, 1992Assignee: Her Majesty The Queen in right of Canada, as represented by the Minister of Energy, Mines and ResourcesInventors: Theo J.

Patent number: 4558031Abstract: A method is described for producing a catalyst or catalyst support having both high surface area, e.g. greater than 150 m.sup.2 /g, and large pore sizes, e.g. greater than 1.0 ml/g of macropores having diameters between 1 and 50 .mu.m. According to the method, a metal oxide is mixed with water and an acid to form a dilute metal gel, preferably containing at least 70% by weight water and consisting of a loose three dimensional network of oxide containing the water evenly dispersed throughout. This gel is slowly dried at a temperature below the boiling point of water whereby a substantial proportion of the water is removed from the interior of the pore structure, leaving the three dimensional network intact. Thereafter, the dried product is calcined to form a novel catalyst or catalyst support having both high surface area and large pore sizes. The novel catalyst is useful as a component of a catalytic cracking catalyst or a hydrocracking catalyst.Type: GrantFiled: January 24, 1983Date of Patent: December 10, 1985Assignee: Her Majesty the Queen in right of Canada, as represented by the Minister of Energy, Mines and Resources of CanadaInventors: Marten Ternan, Basil I.

Patent number: 4519915Abstract: Hot water is an important component in the recovery or extraction of bitumen and heavy oils. This hot water tends to form emulsions with the oil and when these emulsions are broken by demulsifiers and the oil separates, the remaining water retains a black color and cannot be recycled in the process. The black color has been most difficult to remove, but it has now been found that it can quite easily be removed by certain selected adsorbents. These include high ash coal rejects, fly ash from coking gas and red mud.Type: GrantFiled: June 14, 1984Date of Patent: May 28, 1985Assignee: Her Majesty the Queen in right of Canada, as represented by the Minister of Energy, Mines and ResourcesInventors: Albert E.

Patent number: 4376695Abstract: A process is described for the simultaneous demetalization and hydrocracking of heavy hydrocarbon oils. The process permits the recovery of metals such as vanadium and nickel in an economic manner by passing a slurry of a heavy hydrocarbon oil and carbonaceous additive particles, such as coal, in the presence of hydrogen through a confined vertical hydrocracking zone at high temperatures and pressures. A mixed effluent containing a gaseous phase and a liquid phase is removed from the top of a hydrocracking zone, while there is removed from the bottom of the hydrocracking zone a portion of the hydrocracking zone contents containing carbonaceous remains of the additive particles to which is adsorbed the metal residues from the feedstock. The effluent removed from the top of the hydrocracking zone can be subsequently fed directly to a catalytic hydrocracking unit.Type: GrantFiled: April 23, 1981Date of Patent: March 15, 1983Assignee: Her Majesty the Queen in right of Canada, as represented by the Minister of Energy, Mines and ResourcesInventors: Keith Belinko, David J.

Patent number: 4370221Abstract: An improved process is described for the hydrocracking of heavy hydrocarbon oil, such as oils extracted from tar sands. The charge oil in the presence of an excess of hydrogen is passed through a tubular hydrocracking zone, and the effluent emerging from the top of the zone is separated into a gaseous stream containing a wide boiling range material and a liquid stream containing heavy hydrocarbons. According to the novel feature, the hydrocracking process is carried out in the presence of a catalyst consisting of finely divided coal or other carbonaceous material carrying catalytically active metals from Group VIA and Group VIII of the Periodic Table of Elements, e.g. cobalt and molybdenum. The catalyst is slurried with the charge stock and has been found to greatly reduce coke precursors and thereby prevent the formation of carbonaceous deposits in the reaction zone while also being effective in reducing the sulfur concentration of the product.Type: GrantFiled: March 3, 1981Date of Patent: January 25, 1983Assignee: Her Majesty the Queen in right of Canada, as represented by the Minister of Energy, Mines and ResourcesInventors: David J.
