Surfactant studies for bench-scale operation (open access)

Surfactant studies for bench-scale operation

A phase II study has been initiated to investigate surfactant-assisted coal liquefaction, with the objective of quantifying the enhancement in liquid yields and product quality. This publication covers the first quarter of work. The major accomplishments were: (1) the refurbishment of the high-pressure, high-temperature reactor autoclave, (2) the completion of four coal liquefaction runs with Pittsburgh [number sign]8 coal, two each with and without sodium lignosulfonate surfactant, and (3) the development of an analysis scheme for the product liquid filtrate and filter cake. Initial results at low reactor temperatures show that the addition of the surfactant produces an improvement in conversion yields and an increase in lighter boiling point fractions for the filtrate.

Direct Methane Conversion to Methanol (open access)

Direct Methane Conversion to Methanol

Objective is to demonstrate the effectiveness of a catalytic membrane reactor (ceramic membrane combined with catalyst) to selectively produce methanol by partial oxidation of methane. None of the membranes tested in a high pressure system could selectively remove methanol, until a cooling tube was inserted inside the membrane reactor to quench the product stream; this effectively increased methanol selectivity 2[times] during methane oxidation. For both conditions, combined selectivity for methanol and CO is constant, 85%. The remaining product is CO[sub 2]. The membranes were broken when removed from the system; this was remedied when a cooling tube with a smaller diameter was used.

The Hawaiian Monk Seal at French Frigate Shoals, 1988-89 (open access)

The Hawaiian Monk Seal at French Frigate Shoals, 1988-89

This report is based on an observational study on the Hawaiian monk seal, located at French Frigate Shoals in the Hawaiian Islands National Wildlife Refuge. Study took place from April 4th to August 31st 1988 and from March 25th to September 4th 1989. Data was made to conduct atoll-wide beach censuses of monk seals to assess productivity, survival, movements between atolls and islands, and population structure and distribution; furthermore, the study was made to monitor reproduction rates, movement between islands, tagging weaned pups, record injuries and deaths, perform necropsies, and catalogue and destroy debris capable of entangling wildlife.
