  • Patent number: 11759765
    Abstract: A method of making a composite material for dehydration of gases includes the steps of grinding date palm wood fibers to produce a fiber powder, immersing the fiber powder in an alkali solution, filtering fiber powder from the alkali solution to obtain treated fiber powder, drying the treated fiber powder, mixing the dried treated fiber powder with melted polylactic acid to form a composite material, extruding the composite material, and molding and pressing the extruded composite material. The resultant composite material may then be used to dehydrate gas by contacting the gas with the composite material such that water from the gas is adsorbed onto the surface of the composite material.
