PCT No. PCT/DE87/00086 Sec. 371 Date Sep. 19, 1988 Sec. 102(e) Date Sep. 19, 1988 PCT Filed Mar. 2, 1987 PCT Pub. No. WO87/05658 PCT Pub. Date Sep. 24, 1987.The process is of special interest to refinieries in the neighborhood of existing oilfields. The crude oil additionally released in the known manner by the introduction of hot water or steam contains also a so-called petroleum gas consisting largely of methane as well as other combustible gases. According to the invention, this gas is converted in hydrogen using a cracking oven heated by a high-temperature reactor, with steam being produced by the heat released by the cracking oven.
