Abstract: Isopropyl alcohol is a very useful chemical that is widely used in the industry as a solvent. Economical and easy process to make ispopropyl alcohol using novel composite catalyst is described in the instant application. Production of isopropyl alcohol (IPA) from dimehtyl ketone (DMK) and hydrogen (H2) in gas-phase using a ruthenium nano-particle-supported on activated charcoal/nano-zinc oxide composite catalyst is described. Gas phase production of isopropyl alcohol using DMK and hydrogen is also described using optimal time on stream, temperature, catalyst ratio and DMK/H2 ratio. Ruthenium nano-zinc oxide composite catalyst is formulated using different ratios of ruthenium activated charcoal and n-ZnO is described. CAT-IV is shown to be the best performer for the efficient production of isopropyl alcohol.

Abstract: A low-pressure one-step gas-phase process for the production and recovery of methyl isobutyl ketone (MIBK) is disclosed. One-step gas-phase synthesis of MIBK from acetone and hydrogen over nano-Pd/nano-ZnCr2O4 catalyst at atmospheric pressure is used as an example. The said process is designed to recover the additional heat associated with the reactor effluent via heating acetone feed and recycle (mixed acetone) before entering the reactor. A compressor is introduced to the gas-phase process to increase slightly the reactor effluent pressure before this effluent is cooled and fed to a flash drum. The compressed reactor effluent is used to preheat hydrogen feed and recycle (mixed hydrogen) before entering the reactor. The separation scheme of low-pressure one-step gas-phase process comprises of several distillation columns used for MIBK separation and purification.
