WebBesides hydrothermal synthesis, dry gel conversion (DGC) is another main method to synthesize zeolites, which was first reported by Xu and co-workers in 1990. 95 Unlike the hydrothermal synthesis containing a large amount of water, the DGC method contains only a very limited amount of water, which may moderate the species transportation and thus … WebPyrolysis was carried out at temperatures of 300, 400, 500, and 600 °C with a constant rate of temperature change of 10 °C/min; HTL was carried out at temperatures of 270, 300, and 330 °C. The bio-oil yield obtained by HTL (38.8–45.7%) was significantly higher than that of pyrolysis (up to 21.9%). Webical properties of venting fluid, were taken at Cloud, Clam Bed, and SM vent sites. Vent water samples were collected with titanium major samplers and with the Hydrothermal Fluid and Particle Sampler (HFPS) (But-terfield et al. 2004), and processed and analyzed as described in Lilley et al. (1993) and Butterfield et al. (1994, 2004). capita hartshead ltd v byard 2012
