Adsorptive Treatment of Residues on Macroporous Adsorbent for Marine Fuel Production Scheme on Refinery

Journal of Marine Science and Engineering, 2023
Adsorptive treatment using granulated macroporous Al2O3-SiO2 adsorbent is proposed as a preliminary stage for residue pretreatment in refineries. The study evaluates the adsorptive treatment of atmospheric and visbreaking residue at 485–510 °C and 1 h−1 feed rate, resulting in a total liquid product yield of about 73.0–75.0 wt%, coke on the sorbent of ...

Ecosystem uptake and transfer of Sellafield-derived radiocarbon (14C). Part 1. The Irish Sea [PDF]

, 2017
Ecosystem uptake and transfer processes of Sellafield-derived radiocarbon (14C) within the Irish Sea were examined. Highly variable activities in sediment, seawater and biota indicate complex 14C dispersal and uptake dynamics.

Effects of Fuel Injection Mode on Residual Fuel Combustion in High Speed Marine Diesel Engine

JOURNAL OF THE MARINE ENGINEERING SOCIETY IN JAPAN, 1985
To find a basic principle of residual fuel combustion, tests were conducted on heavy fuels of 34.4 cSt and 75.9 cSt at 50°C (200 and 500 sec RW No. 1 at 100°F) using small-sized, high speed diesel engines with a cylinder bore of 110 mm, a stroke of 125 mm and speeds of 2500 and 2600 rpm.
