  • Patent number: 4670238
    Abstract: An improved process for reducing the sulfur content of a flue gas derived from combination of a sulfur-containing fuel by inserting a dry sulfur sorbent material into the flue gas, then humidifying the sorbent-containing flue gas to enhance sulfur removal. The humidified flue gas is then subjected to electrostatic precipitation separation of solids, the first separated portion containing the highest unreacted sorbent values, which values are reinjected into the flue gas.

  • Patent number: 4408572
    Abstract: In a system including an alcohol fuel container, a first catalyst containing reactor, an internal combustion engine, alcohol is passed from the container through the first reactor which contains dissociation catalyst. The alcohol is dissociated in the first reactor to form a combustible gaseous mixture comprising hydrogen. The hydrogen is then fed to the engine. The improvement includes passing alcohol through a second reactor containing dehydration catalyst to form ether. Then passing that ether to the engine for start-up. Thus, the engine may be started using a mixture of ether formed in the second reactor and alcohol and then operated using hydrogen formed in the first reactor.
