The present invention relates to a catalyst for preparing hydrocarbons of carbon dioxide and more particularly, the Fe&#x2014;Cu&#x2014;K/&#x3b3;&#x2014;AlOcatalyst prepared by impregnation which enables producing hydrocarbons in high yield for more than 2000 hours due to its excellent activity and stability.

Catalyst for preparing hydrocarbon

A process for preparing supported nickel catalyst consisting of supporting nickel or metal salt of nickel, alkali metal, alkaline earth metal having low melting point on silicon and aluminum-containing support having high surface area such as zeolite, silica and alumina as an oxide by melting effectively nickel or metal salt of nickel, alkali metal and alkaline earth metal having low melting point is disclosed. This process is characterized in that the supported nickel catalyst prepared by the present invention can be used in reforming reaction of hydrocarbons by using carbon dioxide, steam and oxygen as an oxidant. Metal salts used in the preparation of supported nickel catalyst is generally nitrate, chloride, acetate and carbonate having low melting point of 500&deg; C. or less. The contents of nickel, alkali metal and alkaline earth metal of the catalyst are 1 to 20% by weight, 10% by weight or less and 20% by weight or less, respectively. The calcination temperature of the catalyst is in a range of 300&deg; C. to 1200&deg; C.

Process for preparing supported nickel catalyst for reforming hydrocarbons

A method for preparing a high-heat-resistant-epoxy-resin composition which comprises adding, as catalytic curing agent, a pyrazinium salt having a benzyl group to difunctional and multifunctional epoxy resin and thermoset resin having a similar structure. The epoxy-resin composition obtained by the present invention is excellent in its impregnating property, processability, impact resistance, drug resistance, electric-insulating property, and adhesiveness.
