Granted: 2005-04-12
Abstract: A 2-Stage fluidized bed type reducing apparatus and a reducing method for fine iron ore of a wide particle size distribution with increasing the reducing gas utilization degree are disclosed. Fine iron particles dropping through the holes of a gas distributor (102, 202) can be recycled into the fluidized bed type furnace, thereby preventing an impediment of the reducing gas flow due to abnormal defluidizing or channeling. A first fluidized bed type furnace (100) dries, pre-heats and pre-reduces the fine iron ore, and a second fluidized bed type furnace (200) finally reduces the pre-reduced iron ore. Downstream of the respective fuidized beds, there are installed intermediate hoppers (500, 600) and gas/solid sealing valves (501, 503, 601, 603). Thus the fine iron ore particles which drop through the holes of gas distributors (102, 202) during the abnormal operation are recycled to the furnaces (100, 200) Accordingly the gas flow is not impeded.

Title: A process for hydroconverting a heavy hydrocarbon chargestock
Inventor: HAN BAOPING
IPC: C10G47/12
Filed: 2002-01-02
Granted: 2010-03-09
Abstract: The present invention discloses a process for hydroconverting a heavy hydrocarbon chargestock, wherein said chargestock oil is first contacted with a highly active homogeneous hydrogenation catalyst to effect the hydrogenation reaction so that macromolecular radicals of the residue (the precursor of coke) form as less as possible, thereby decreasing the output of coke in the hydrocracking of the residue; when the reaction proceeds to a certain extent, a solid powder is added to adsorb the macromolecular radicals of the residue formed during the reaction and lower their reaction activity, thereby preventing them from further condensing to coke and/or depositing due to polymerization. The synergetic action of the two sorts of substances makes it possible to produce substantively no coke or less coke during the hydrogenation of residue in a suspension bed and prolong the operation lifetime of the unit.
