To date, first and second generation processes have been integrated by the adoption of grassroots design methodologies while, in reality, their coupling is far more complex.
Attention is focused on second generation processes starting from lignocellulose as a sustainable feedstock, thus circumventing the food vs fuel dilemma, and on the green features of these new processes.
Consolidation of the second-generation with the first-generation process can potentially reduce the downstream processing cost for the second-generation process as well as providing the first-generation process with energy.
A first-generation process utilized Pd OAc 2/PtBu3·HBF4 catalyst system with a strong base NaOtBu.
Second-generation Process artists don't fade away, they just keep marshalling orderly accumulations of this or that material as if Eva Hesse never existed.
Integration of the first-generation process into the second-generation (2 G) process also increases the ethanol concentration, which will result in a decrease in the cost of distillation, thus improving process economy.
Under this model, second-generation biofuels complement and enhance first-generation processes, rather than replacing them outright.Three plants in America are expected to start producing cellulosic ethanol from waste corn cobs, leaves and husks in 2014: POET-DSM Advanced Biofuels (75m litres) and Dupont (110m litres), both in Iowa, and Abengoa (95m litres) in Kansas.
Mr Klein-Marcuschamer has made his model open-source in an effort to help the industry find ways to make biofuels more competitive.Even if second-generation processes can be economically scaled up, however, that might in turn highlight a further problem.
Integration of first-generation and second-generation processes also increases the ethanol concentration, resulting in a reduction in the cost of the distillation step, thus improving the process economics.
In the first generation of process automation, logistics companies were able to track in-flight deliveries each time they arrived at a key milestone in their journey, the arrival of a parcel at a depot, port, or at the customer's location could all be tracked.
