Abstract: In the preparation of a methane-rich gas, a normally liquid hydrocarbon having an upper boiling limit of 350 C. and containing from 6 to 30 carbon atoms per molecule is heated to 350-400 C. and passed, together with 1À5 to 3 kg. of steam per kg. of hydrocarbon also heated to 350-400 C., into a reactor in which it is cracked at below 450 C. using a catalyst comprising metallic cobalt or nickel on a magnesium silicate carrier, the resulting gas is cooled to 200-250 C., passed over a methanation catalyst and then scrubbed to reduce its carbon dioxide content to not more than 4% by volume. A suitable cracking catalyst contains 5-40% by weight of cobalt or nickel and may contain an activating addition of 0À05 to 3% by weight of platinum. The methanation catalyst may be the same as the cracking catalyst or may be a different catalyst such as an alumina carrier containing nickel.

Title: Control circuit for knitting machine
IPC: D04B15/78
Filed: 1977-08-25
Abstract: A control circuit for a knitting machine with electromagnetic needle selection has a shaft position coder to clear the transmission of instructions from a memory to the machine in synchronism with the presence of consecutive selection elements.
