Patent ES-342136-A1 (ES)
Title: Steam Reforming Process to make Fuel Gas
IPC: C10G47/00
Filed: 1967-06-21
Abstract: A lean gas, i.e. one consisting essentially of H 2 and CO, is reacted at elevated temperatures in the presence of a nickel-uranium catalyst with steam and a hydrocarbon feedstock under such conditions that the reaction is exothermic or thermally neutral, to produce a gas comprising H 2 , CH 4 , and oxides of carbon. An essential condition of the reaction is that the Operating Ratio (O.R.) is less than 0À06, the O.R. being the Initial Inert Ratio (I.I.R.) divided by the Carbon Ratio (C.R.), the I.I.R. being the proportion, expressed as a fraction, of gases present in the dry lean gas (other than H 2 , CO, CO 2 ), and the C.R. being the ratio of the weight of carbon in the feedstock added to the lean gas to the total weight of carbon content in the lean gas (both referred to a given time). A two-stage process is described, the first stage producing the lean gas by steam reforming a hydrocarbon feed at elevated temperature over a catalyst which may be the same as the nickel-uranium one employed in the second (inventive) stage. The catalyst, which in the second stage may be a fixed or fluidized bed, comprises Ni and/or NiO and U 3 O 8 and/or UO 3 , optionally on a carrier of aluminium oxide or alkaline earth metal oxide, such catalysts being described in Specifications 1,039,206, 1,196,411 and 1,196,412. The final gas may be diluted with lean gas which has by-passed the second stage reactor. Reaction conditions are described in detail for both stages.

Title: Device for collecting solids in a centrifuge
IPC: B04B11/02
Filed: 1969-10-30
Abstract: The discharge end of a pusher centrifuge drum 2 is partly enclosed by a flexible member 6 of circular cross-section on to which solids are thrown from the drum, member 6 being rotated about its longitudinal axis by electric motor 7. The resulting flexing of member 6, which may be rubber, plastics or a covered helical spring, prevents solids sticking thereto. In Fig. 3 (not shown) the flexible member is hollow and there is a motor at each end, whose rotor is connected to the centrifuge housing and whose stator is enclosed in and secured to the end of the member. The two motors rotate in opposite directions, and small speed variations cause additional flexing of the member. The member in Fig. 4 (not shown) is also hollow and is supported by bearings to be rotated about the circular axis of a fixed ring (18) by a motor (21) in one end of the member.

Title: Furnace circuit for variable pressure once-through generator
IPC: F22B37/32
Filed: 1972-12-27
Abstract: A variable pressure vapor generator of the once-through type in which circulation is established at normal loads by the generator feed pump. However, at start-up and loads below about 50 percent, evaporation in the generator furnace enclosure is carried out only to a vapor-liquid mixture. At least a minimum flow, for instance about 10 percent flow, is maintained by the generator feed pump, and circulation in the furnace enclosure is established by natural recirculation of the liquid portion of the vapor-liquid mixture, assisted by the feed pump flow. By the invention, turbine throttle pressure is varied in response to load demand, and fluid pressure within the vapor generator circuit is varied essentially in step with the throttle pressure.
