  • Patent number: 10118824
    Abstract: The invention relates to a process for purifying synthesis gas, comprising at least one stage for separating the crude synthesis gas to be treated into at least two effluents, namely a first part and a complementary part, in which the said first part is subjected to a carbon monoxide conversion stage with steam and the said complementary part is subjected to a COS and HCN catalytic hydrolysis stage, the two gas flows, namely the first part and complementary part, are then each treated separately in two stages intended to remove acid gases such as CO2 and H2S, by washing with aqueous solutions of specific amines, before a recombination stage of the two treated effluents.

  • Publication number: 20130153616
    Abstract: A weight-bearing accessory for a hand-propelled cart having a diagonal chassis includes a frame, which is configured to receive and hold one or more containers within the frame. At least one first quick-connect is configured to removably connect the first end of the frame to an upper part of the diagonal chassis. A first strut is coupled to support the second end of the frame. A second strut is connected to a joint at the lower end of the first strut. At least one second quick-connect is configured to removably connect the distal end of the second strut to a lower part of the diagonal chassis. The accessory is designed to fold easily and conveniently when not in use, while the structure of the accessory and the support that it provides prevent the cart from tipping over, regardless of the distribution of the weight carried by the accessory.
