Naptha-cracking process: more propylene with less energy

Article Abstract:

A novel means of increasing the production of propylene from naptha crackers has been developed in Japan. The technique, which is capable of raising the propylene:ethylene ratio to 0.7:1 from the conventional 0.6:1, was developed at the National Institute of Materials and Chemical Research in Tsukuba, Japan in cooperation with four member companies of the Tokyo, Japan-based Japan Chemical Industry Assn. The process utilizes a lanthanum catalyst supported by zeolite in a fixed bed.

How to expand a pipe without busting up the joint

Article Abstract:

Daido Steel Co of Nagoya, Japan, in cooperation with Amsterdam, Netherlands-based Royal Dutch/Shell Group, has developed a new technology that is capable of expanding oil-drilling pipe diameters by as much as 20%. The technology, which is expected to be applied in deep-sea drilling projects, is capable of expanding a 5-in-diameter pipe to a 6-in-diameter pipe. The increase in pipe diameter will increase oil production by 44%.

Gas-generating chemical may put more safety into auto safety bags

Article Abstract:

A consortium led by Japan's New Energy and Industrial Development Organization is developing a substitute for sodium azide, the gas- generating chemical used in air bags but which is suspected of being toxic. Its replacement, BHT diammonium salt, is not new but is expensive. BHT salt would also be activated in air bags by an ignitor but would produce mostly nitrogen gas. The consortium is studying ways of producing BHT salt without the addition of manganese dioxide and the production of manganese carbonate waste.
