Abstract: 1,005,133. Reactors. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. June 12, 1964 [July 4, 1963], No. 26641/63. Heading G6C. A liquid moderated reactor has its moderator within a calandria tank which tank has a first group of calandria tubes arranged on a first geometrical lattice for housing pressure tubes containing fuel and coolant, and a second group of calandria tubes defining voids within the moderator and arranged on a second geometrical lattice of the same pitch as the first but displaced therefrom, to provide an overall symmetrical arrangement. The need for such an arrangement of voids in the moderator is economic, and arises as a result of the desirability of using side branch pipes 11 for. coolant connections so as to leave the pressure tube ends 3b free for fuel element changing; it is thus necessary to use a relatively large pitch for the pressure tubes 3. Some of the void tubes 8 may accommodate control and shut-down elements 15, ionization equipment 16 and flux scanning wires 17. The reactor illustrated is moderated by heavy water 14 and cooled by light water, which boils in the pressure tubes 3 containing fuel assemblies 9. The calandria is supported on bearings 13, and the pressure tubes are of three-part construction, having end parts of stainless steel and intermediate core parts of zirconium alloy. The lattices of the pressure and void tubes (Fig. 2, not shown) are each of square form and superimposed to give a composite regular square lattice in which each pressure tube is surrounded by four void tubes and vice-versa. Specification 897,457 is referred to.

Title: Improvements in or relating to a method of producing diphenyl and homologues thereof
IPC: B01J19/24
Filed: 1951-11-16
Abstract: <PICT:0723114/IV (b)/1> Diphenyl and its homologues are produced by passing a monocyclic aryl hydrocarbon through a tubular reactor heated substantially throughout its entire length to a temperature which is constant and lies within the limits of 773 DEG  and 1073 DEG K. thereby converting from 1-30 per cent by weight of said hydrocarbon in a sojourn time of from 0.56-100 seconds.  The reaction temperature and sojourn time are correlated in accordance with the equation <FORM:0723114/IV (b)/1> <FORM:0723114/IV (b)/2> where k is the reaction velocity constant, t is the sojourn time, a is the initial concentration of the hydrocarbon, x is the amount decomposing in time t, A has values of 4x108 and 1.1x109 when E has values of 45738 and 49006 cal./mol.  DEG  K. respectively, e is the base of the natural logarithms, R is the gas constant having the value 1.986, and K is the absolute temperature.  It is also desirable to correlate the diameter of the reactor tube (d), the vapour velocity (u), the vapour density (p), and the vapour viscosity (U), so that the Reynolds' number (d.u.p/U) is from 600-100,000, particularly 3000-70,000.  By recycling unreacted benzene, an overall conversion to diphenyl of about 93 per cent is obtained with 5 per cent conversion per pass or about 65 per cent with 30 per cent conversion per pass.  The pressure may range from 0-100, preferably 0-40, p.s.i.g.  A graph is given wherein conversion is plotted against sojourn time at different temperatures.  Time and temperature having been selected, the conversion (x) is read off when the value of k can be determined from the above equation.  The activation energy E is determined from the equation <FORM:0723114/IV (b)/3> and hence the values of A. Apparatus may comprise coiled preheater tube 1, heated from power lines 12, 15 connected to copper plates 11, 14, and connected to exit tube 13 from which samples of product can be collected via line 20. Tube 13 is connected to reactor tube 24 surrounded by alundum pipe 26 wrapped in nichrome heater ribbon.  Tube 24 terminates in straight section 32 connected to exit pipe 33. Thermocouples 7, 29, 34, 35 are provided.  Product vapours pass to condensers 42, 43, 44.  Tubes 1, 24 may be of nickel steel, mild steel, iron, copper or copper-manganese alloys.
