Improved Charcoal Production System. A low-cost retort kiln for a more environmentally friendly charcoal production from bio mass.
The invention provides a process for purifying crude glycerol such as splitters crude, soaplye crude and methanolysis crude which comprises a microfiltration step over a filter material on a ceramic support preferably comprising alumina. Preferably the filter material comprises zirconia and/or alumina. Preferably the process further comprises the step of distillation and/or treatment with ion exchange resins. Also the process may involve a combination of microfiltration and ultrafiltration.
The present invention generally concerns a process for the purification of crude glycerol obtained as a by-product of industrial processes such as saponification, hydrolysis and transesterification with low chain alcohols of natural oils and fats. The present invention particularly concerns the purification treatment of crude glycerol obtained as a by-product of the biodiesel production from vegetable oils and animal fats, aiming to obtain a concentrated purified product.
In this paper, a new two-step process to enhance the acetic acid yield from cellulosic
biomass is proposed. The first step is to accelerate the formation of lactic acid in a
hydrothermal reaction with the addition of alkali, and the second step is further convert
the lactic acid produced in the first step to acetic acid by oxidation with newly added
oxygen. Results showed that the addition of an alkali promoted the formation of lactic
acid in a hydrothermal reaction of glucose. An acetic acid yield of 27% on the carbon
base was obtained by the two-step process. The purity of the acetic acid on carbon basis
was 90%. Use of Ca(OH)2 as an alkali has the benefit of obtaining calcium acetate as the
final produc
