Title: Hydrogenative reforming of gasoline and other naphtha fractions
IPC: C10G59/02
Filed: 1953-08-24
Abstract: Hydroforming of naphtha or gasoline is effected in several stages in the presence of a platinum catalyst having strong hydrogenatingdehydrogenating activity, in the initial stage there being absent the combination of alumina and gaseous halogen or halide, and in a subsequent stage only there being present with the platinum catalyst an alumina carrier and a minor amount of gaseous halogen or halide mixed with the stream of naphtha and hydrogen, whereby the initial stage is more favourable for hydrogenation than isomerization and the subsequent stage more favourable for isomerization.  Platinum on alumina may be used in the initial stage and halogen added only to the effluent passing to the subsequent stage.  Alternatively, aromatics formed in the initial stage may be separated, and the residual product only passed with halogen to the subsequent stage, the isomerized product then being recycled to the first stage preferably with fresh naphtha.  The amount of halogen is generally at least 0.001 per cent by weight of the naphtha, and preferably 0.005-0.1, using catalysts containing up to 1 per cent Pt on activated alumina.  Pressures may be higher in an initial stage or stages and lower in a subsequent stage or stages.  Thus, with a C6-C8 charge, initial hydrogen partial pressure is not less than 400, e.g. 450-500 p.s.i., and pressure in a final stage is not above 300, e.g. 250 down to 150 p.s.i.  With higher boiling fractions, higher pressures may be used.  With cuts boiling over a range of more than 100 DEG  F., the final stage pressure should be at 25 per cent less than that of the first stage.  Temperatures are in general 850-1050 DEG  F., liquid hourly space velocities 0.5-10, and hydrogen to oil molar ratio 3-10, being the same or different in the stages.  The feed may be fractionated into higher and lower boiling fractions which are treated in separate series of reactors under different reaction conditions or the higher fraction may by-pass the initial stage subsequent stages.  Naphthas of B.R. 180-400 DEG  F. are preferably cut at about 260-300 DEG  F.  In an alternative method of operation, a carrier other than alumina, such as silica gel, activated carbon or other non-acidic carrier having little or no cracking activity is used in the initial stage.  Hydrogen-rich gas from the final reactor may then be recycled to the initial one even if halogen is present.

Title: Improvements in or relating to steam power installations including forced-flow, once-through boilers
IPC: F22B29/10
Filed: 1960-07-04
Abstract: 946,406. Controlling forced flow steam boilers. SIEMENS - SCHUCKERTWERKE A.G. July 4, 1960 [July 3, 1959], No. 23373/60. Heading F4A. In a steam power plant including a forced-flow, once through boiler of which the supply of fuel and air to the boiler furnace and the supply of feedwater are separately controlled, there being automatic means for ensuring that the rate of supply of feedwater corresponds to the rate at which steam is withdrawn from the superheater as required by the load on the boiler, no direct measure of the rate of flow of superheated steam is made but means are provided to give controlling signals dependent on said rate, for example, signals which are derived from outlet superheater pressure, turbine regulating oil pressure or from the electrical output of the turbo-generator. As shown in the drawing, a feed pump 11 forces water through a regulator valve 12 and rate-offlow constriction 13 into the boiler tubing which consists of economizers 14, 15, evaporators 16, 17, and a superheater 18. At a point 52 between the evaporators 16, 17 the pressure is measured and a pressure dependent signal P 1  is obtained. Feedwater is injected into the tubing after the evaporator 17 under the control of a valve 33 the setting of which is controlled by steam temperature signals obtained at points T 1 , T 2  at the inlet and outlet respectively of the superheater 18. The steam pressure is also measured at the superheater outlet at 53 and a signal P 2  is obtained, this signal acting to correct the signal P 1  when load variations occur. The steam passes through a valve 20 to the high-pressure stage 21 of a turbine and then to the low-pressure stage 23 by way of a reheater 20A and the valve 20. The steam exhausts into a condenser 24 whence condensate is pumped into an accumulator 30. A pump 31 draws water from the accumulator and returns it to the boiler through a bled steam heater 25. The valve 20 is controlled by a load dependent signal u derived from the turbine regulator 65 to which is applied a signal representative of turbine speed derived at 67. A signal e derived from changes in the pressure of the oil in the turbine regulating system passes to the boiler load-setting device 35. The load-setting device emits a load-dependent signal a which is passed to a control device 36 controlling the speed of the feed pump 11, the control device also receiving a signal representative of the ratio between the rate of flow of injected water measured at an orifice 61 and the rate of flow of the main feedwater stream measured at 13. The coal feed to the furnace is regulated according to variations in the steam pressure P 1  as corrected by P 2 , the air supply being adjusted either manually or automatically according to measures of O 2  or CO 2 . A load variation limiter 62 is provided to prevent unallowably high temperature changes in the turbine. Specification 896,502 is referred to.
