Abstract Supercritical water gasification of weak sulfur-free black liquor (BL) was performed in a batch autoclave at temperatures between 430°C and 470°C, pressure between 24 and 27 MPa and residence time between 2 and 63 min. Results show that the gas produced was a mixture of mainly hydrogen, methane, and carbon dioxide. Maximum conversion was achieved at 470°C and 60 min. Energy recovery (ER, ratio between the energy in the gas and in the initial BL) was 46%. Thirty-four percent of the carbon and 53% of the hydrogen initially present in BL were converted into gases. Nearly 15% of initial organic carbon remains in the liquid phase and consists mainly of phenolic compounds, which are stable under those conditions. A higher temperature is needed to convert all the organic carbon. Thermodynamic equilibrium should be reached at 700°C leading to a complete conversion and a better efficiency. Sodium recovery is close to typical kraft recovery value and compatible with causticizing.

This article seeks to advance conversation on the literary and political agency of fugitive slave narrators and their far-reaching archival footprints by focusing on the evolution of John Brown’s narrative of John Glasgow, a Demerara-born free Black sailor with whom Brown toiled side by side on a Georgian plantation. In British and U.S. abolitionist discourse, Glasgow’s tragic story—he was imprisoned under Georgia’s seamen law upon arriving in Savannah and eventually fell into bondage—made him the symbol of the southern seamen acts’ egregious infringement of British freedom. Brown, a formerly enslaved expatriate resident in England, told this tale in his autobiography Slave Life in Georgia, but the authorship of this story has some ambiguity. It is believed by some scholars that the narrative’s editor, London-based White abolitionist Louis Alexis Chamerovzow, concocted the tale. By drawing on newly discovered documents, this article demonstrates that Brown originally attributed Glasgow’s enslavement to kidnapping by deceit, not to a Black seamen law. Furthermore, an examination of British diplomatic dispatches and the details of the Black seaman law operating in Savannah at that time posits the likelihood that Glasgow became enslaved by deception rather than law. What do we make of these findings? Instead of marshalling them to confirm Chamerovzow as the story’s creator, this article speculates that John Brown himself invented the Glasgow story and imagines a transatlantic Black political circuitry connecting England and Canada.
