  • Process for vapor-phase methanol carbonylation to methyl formate, a catalyst used in the process and a method for preparing the catalyst
    Patent number: 9944587
    Abstract: A process for vapor-phase carbonylation of methanol to methyl formate, whereby a feed gas containing methanol, carbon monoxide, hydrogen and oxygen is passed through a reactor loaded with a supported nano-scaled platinum group metal heterogeneous catalyst to produce methyl formate by a vapor-phase carbonylation reaction, under reaction conditions with a space velocity of 500-5000 h?1, a temperature of 50-150° C. and a pressure of 0.01-2 MPa. Supported nano-scaled platinum group metal heterogeneous catalysts are prepared via ultrasonic dispersion and calcination. Methyl formate is produced and isolated under relatively mild conditions.

  • A PROCESS FOR VAPOR-PHASE METHANOL CARBONYLATION TO METHYL FORMATE, A CATALYST USED IN THE PROCESS AND A METHOD FOR PREPARING THE CATALYST
    Publication number: 20160332953
    Abstract: A process for vapor-phase methanol carbonylation to methyl formate, a supported nano-scaled platinum group metal heterogeneous catalyst used in said process and a method for preparing said catalyst are disclosed. A feed gas containing methanol, carbon monoxide, hydrogen and oxygen is passed through a reactor loaded with supported nano-scaled platinum group metal heterogeneous catalyst to produce methyl formate by vapor-phase carbonylation reaction, in the reaction conditions with a space velocity of 500-5000 h?1, a temperature of 50-150° C. and a pressure of 0.01-2 MPa. The active component of the supported nano-scaled platinum group metal heterogeneous catalyst is platinum group metal with a particle size of 0.5-10 nm.
