  • Patent number: 8969606
    Abstract: These disclosures relate to preparing nickel metal (Ni(0)) suited for use in catalyst systems, such as nickel complexes with phosphorus-containing ligands, useful to catalyze the hydrocyanation of ethylenically unsaturated compounds. The methods described herein can include use of steam during reduction of nickel.
    Type: Grant

  • Patent number: 8906334
    Abstract: The invention includes an apparatus and process for the catalytic production of HCN from a feed gas of ammonia and a hydrocarbon gas by means of heat tubes supplying heat to the feed gas stream and heat tubes for removal of heat from the products. The invention further includes a process for N2O abatement comprising transferring heat from an exothermic N2O degradation reaction through a heat pipe.

  • Patent number: 5472680
    Abstract: A Process for the conversion of N.sub.2 O to NO by heating a gas stream containing N.sub.2 O by contact with a heated heat exchange surface to a temperature of about 400.degree. to 700 degrees C., and then heating the gas to a temperature of about 850 degrees C. while the gas is not in contact with a heated heat exchange surface, and spontaneously and decomposing the N.sub.2 O and recovering NO.
