Abstract
The liquefaction of lignohemicellulosic waste by processing with carbon monoxide and water for 10 minutes at 250/sup 0/-440/sup 0/C and 40 to 70 atm initial pressure in a rocking autoclave produced benzene-soluble heavy oil in yields up to 80%. High conversion and yields were favored by high thermal stress, short reaction times, and sufficient hydrogen to prevent radical recombination in the critical liquefaction stages. The addition of sodium or calcium hydroxide, sodium carbonate, iron oxide, etc. in small amounts gave good oil yields under less severe conditions. Lignins from rice straw, bagasse, and other grasses gave higher yields than the woody lignin obtained from cotton stalks. In products obtained by liquefying black liquor lignohemicellulose from an Eyptian rice straw pulping plant, the hydrogen-carbon atomic ratio was 1.0 to 1.3:1.
