Abstract: The present invention discloses a catalyst useful in converting carbon monoxide and water to hydrogen and carbon dioxide (water gas shift reaction), which includes a metal oxide carrier and 0.1-10% Pt and 0-5% Re supported on the carrier, based on the weight of the carrier. The carrier contains copper oxide, alumina, and a metal oxide selected from zinc oxide, chromium oxide and magnesium oxide. The present invention also discloses a method for reducing the content of carbon monoxide in a hydrogen-rich reformate gas.

Abstract: Eyeglasses with a one-piece lens rapidly changeable includes a frame pivoted with two temples at both sides and a one-piece lens fitted in the frame. The frame has two nosepieces and each having a flat supporting edge on its outer surface, and a hollow part formed inside a bridge and above the two nosepieces for a waist formed in a middle portion of the lens to be fitted in, letting two upper edges of the lens attached against the outer surfaces of the frame, and two central edges of the lens rested against the two flat supporting edges of the two nosepieces, whereby the frame and the lens can be joined together by correspondingly fastening and positioning to each other both in inside and outside attachments so as to achieve a firm assemblage and allow the lens to be fitted in or taken off the frame with fastness and convenience.
